Increase the compression ratio and the starter isn't happy. Increase the temperature and it gets grumpy. Mix high temperature engine and ambient with a higher-than-normal static compression ratio and the starter becomes downright cantankerous. To make matters worse, whenever the thermometer really rises, you too can personally approach the boiling point, particularly if you have a Corvette that refuses to crank over, let alone start.
Sound familiar? If it is, then you need to check out the following pages. It's a look at modern starting systems, aimed directly at modified Corvettes that, appropriately, have added heat under the hood as you know it's an all too familiar saga--adding horsepower adds heat.
And it's jammed with real cures for hot starting headaches. Take a look. You won't be sorry. The latest mini-starters deliver a whopping 50 percent more torque to the flywheel or flex plate than a conventional original equipment Delco starter. Internally, the starter features a number of special features, including heavy-duty bearings. This design not only allows for long service life, it is also less susceptible to heat or cold problems. Geared Reduction Why is it that starters give up at the worst possible moment--such as when you're at a car show or cruise night and you jump into your Corvette to profile and for the lack of a better term, to show off?
Those are tough questions, and they've been addressed in countless magazine pages by way of a plethora of quick fixes rewired starters, Ford solenoids, heat shields, header wraps, etc. But the real answer is the starter that's bolted to the side of the block. Let's back up a bit: Decades ago, racers discovered the gear reduction starter--a design that was initially popularized by the old Chrysler Corporation.
Those Mopar-based gear reduction drive starters worked. But the trouble with the Mopar system was and still is weight. That starter was a very hefty piece--try bench-pressing one a few times and you'll know exactly what we're talking about.
And to add to the troubles with the Chrysler-configuration starter is the inherent complexity of the unit. Sure it will start a hot, large displacement engine with ease, but if you use one, the considerable superfluous mass is on the wrong end of the Corvette.
Then racers and manufacturers noticed something: Many Japanese vehicles are also fitted with gear reduction starters. In-line four cylinder engines power many of those cars. It's been said that the firing order arrangement of an in-line engine can actually create more difficult starting problems than those associated with V8 power plants. Just as important, those "off shore" starters proved small, light and durable.
Lights went off. In terms of overall size, a mini-starter such as this model from McLeod is considerably smaller than something like a stock Corvette Delco starter. Overall weight is approximately 10 pounds less than a conventional starter and yes, it's almost 40 percent smaller.
When compared to an iron nose HD Delco Corvette starter, the weight savings are even more impressive. Increasing Starter Torque What was really needed was a lightweight, simple gear reduction starter that combined the best of the vintage Mopar designs and the later Japanese configurations.
Given this situation, several aftermarket companies came up with a new starter design such as the McLeod "Mini Hy-Tork" starter shown in the accompanying photos. Why is this important? Typically, a starter motor will draw higher electrical energy loads at low turning speeds. The gear reduction format solves that problem. Loads are decreased, windings are not as likely to become overheated and far less current is demanded from the battery. In the end, a starter such as the McLeod only requires roughly amps of current to function that could be as much as half of the draw found with a conventional starter under this condition.It soon became apparent that good deals on C5s and early C6s could be found, but C4s were even better values.
In fact, C4 prices were so low that I shifted the focus of my car-searching attention to that generation. Make that re-grew on me.
C4 Corvettes are unique animals, and I began to do my homework on the problems that plague these cars. Generally speaking, the later the model year, the better in terms of reliability, performance and desirability. Eventually, as my online searching continued, I stumbled upon a standout candidate.
It was a Competition Yellow coupe with the ZF six-speed manual transmission and a black leather interior. I knew yellow was a rare color for the year. However, the sparsely worded Craigslist ad from the private seller offered few details, which can be a warning sign. If you look beyond your immediate area, limit your search to areas where you know someone who can perform an inspection. I spoke to the seller prior to sending Bruce out to view the Corvette, and his answers were sufficient to warrant the inspection.
I also asked about the status of the brakes, tires and clutch; the owner reported they were all in excellent condition. I was up front about my long-distance situation and told him Bruce would make arrangements to inspect the car. Bruce crawled inside and under the car, starting it and letting it idle long enough to ensure the cooling fans kicked on, and then he took it for a test drive. His unbiased inspection report delivered the bad with the good.
That was a telltale sign of a worn tilt-steering knuckle. This common problem is usually caused by drivers who use the steering wheel to help hoist themselves out of the car. The black leather upholstery, while showing some wear, was still in very good condition, with no splits or major cracks.
There were no apparent issues with the dashboard, either. On the test drive, Bruce reported excellent performance from the horsepower L98 Tuned Port Injection engine.C4 Corvette: Starter, Ignition Control dswdworsted.pwg Update
The car started, drove and stopped as expected, with no vibrations, noises or unwelcome surprises. It had been fitted with an aftermarket short-throw shifter and aftermarket radio, but the seller would include the originals with the sale of the car.
Before proceeding with the purchase, however, I researched the issues Bruce reported. After crunching the numbers, the cost of repairing them seemed reasonable, especially since I could do some of the work myself. I was more swayed by the recent brakes, tires and clutch. All are expensive items on their own, which could add up to several thousand dollars if they needed attention after the purchase, potentially flipping the low price of entry for the C4 on its roof.
Before giving the green light, I performed a CarFax background check on the Corvette. In the end, it was an easy and straightforward transaction that went off without a hiccup. Then I made arrangements to fly out and pick up my Corvette. The wisdom of the purchase would be put to the test in a nearly 2,mile road trip, including several mountain ranges, between Seattle and Detroit.Produced from tothe C4 is one of the most popular Corvettes ever made.
Chevrolet made many C4s over the years, and their relatively low price made them a good entry-level, or starter, sports car. The model did change over the decade-plus that it was in production, and some have held their value in the collectors' market better than others. Chevrolet designed an all-new Corvette in the early s, but the prototypes—about 40 in all—produced for the model year had serious quality issues.
Not only were those not sold to the public, but these quality issues also delayed the subsequent production of fourth-generation Corvettes until the model year. Despite the setback, was the second-largest production run in Corvette historywith over 51, cars produced. Overall, C4 Corvettes make up the second-largest group after the C3, of which aboutcars were built in that generation's year period. The design of the new generation Corvette was distinctively different from previous models.
Once you see a C4—with its futuristic, slightly squared off front and back-end—you'll never mistake this generation for any that came before or since. Also worth noting is that the convertible Corvette returned in after an year absence.
Both major and minor changes were made to the C4 during its production run, and a few special editions were also produced. The standard engine power in the C4 Corvettes ranges from horsepower in a model up to horsepower in one built in A engine can put out horsepower.
Base Corvettes have a horsepower LT1 engine. Certain special editions such as the Callaway twin-turbo models can generate up to horsepower. These are naturally more expensive and hard to find. The — Corvettes are by far the lowest-priced 'Vettes on the market. As such, base-model C4 Corvettes are not generally considered collectible, and it's doubtful they ever will be. Essentially, a C4 from the '80s makes a good starting point for an enthusiast's ride, but it is a poor investment for resale.
The C4 body and frame debuted in after the quality issues of delayed the Corvette's release. The second-largest number of Corvettes produced in any year were produced in —51, cars in total. The suspension for this year was softened 25 percent from This was also the first year that Bosch fuel injection was used.
Total production for this year was 39, The Corvette convertible reappeared this year, after an year absence. All 7, of these convertibles were built as Indy pace car replicas. The engine and horsepower remained the same as the previous year. Total production for this year was 30, cars, 10, of those convertibles.

It took a few time to start and gradually become worse. No fluid leaks what so ever. Some of them, such as "washed out" LCD gauge-cluster displays and electrical gremlins, are fairly well-known, while others, including worn tilt-steering knuckles, required deeper, more specific dives into the C4 ownership realm to uncover.

It will crank over for an extended amount of time before it will fire up.Once started, everything works perfectly—until I shut it off. I would like to repair the car myself to save some money.
Is it possible that I just need a good tune-up? A: It sounds like your Corvette is an ether junkie, but I think with a little rehab we can get it back on the right track. Faulty fuel pump Restricted fuel filter Faulty fuel-pressure regulator Leaking fuel injectors Faulty oil-pressure sending unit Faulty pickup coil located inside the distributor Throttle-position-sensor TPS voltage too high Faulty mass-airflow sensor MAF Faulty coolant-temperature Sensor Faulty engine controller.
When the key is turned to the Run position, the fuel pump will activate for two seconds, pressurizing the fuel rails and giving a reading of between 40 and 42 psi of pressure. The reading should jump to psi once the engine is started. If no fuel pressure is present, use a test light to verify that all of the fuses are working.
Fortunately this is fairly easy on C4 Corvettes. Just remove the cover under the gas-door lid to reveal the pump. Next, have someone turn the key to the Run position and see if the pump activates. If not, tap on the pump while someone cranks the engine. If the vehicle starts, the pump has an internal failure and will need to be replaced. If the vehicle does not start, check for battery voltage and ground at the fuel pump using a Digital Volt Ohm Meter DVOM while someone cranks the vehicle.
If voltage and ground are present, the fuel pump has an internal failure and will need to be replaced. If voltage and ground are not present while the vehicle is being cranked, check to see if the fuel-pump relay is being energized. A great way to test a circuit is to remove the top of a relay and simply look inside. You can also manually close the contact on the test relay by pressing the points closed with your finger.
If the fuel pump comes on and functions properly, the fault is neither the pump nor the wiring from the relay to the pump.

At this stage, possible faults include the battery voltage being supplied to the coil of the relay or any circuit controlling this voltagethe ground being supplied to the coil of the relay from the engine controllerand the relay itself.
For the fuel-pump relay to become energized, oil pressure must reach 4 psi. At that point the switch will close, allowing the fuel pump to run.
An abnormally long crank time or a no-start could indicate a faulty oil-pressure switch Image C. Note: GM had a run of bad oil-pressure switches controlling the fuel pump. These defective switches can cause a long crank time. There are two oil-pressure switches on C4 Corvettes; one controls the gauge and normally has one tan wire, while the other switch is longer and has two wires. As a result, changing fuel filters regularly is more important than ever.
Remember, the fuel pump is cooled by fuel flowing through it. If the fuel filter becomes restricted, there will be less volume passing through the pump, which could cause it to overheat and fail. Next, check for a leaking fuel-pressure regulator. A leaking regulator usually caused by a ruptured internal diaphragm can allow raw fuel to be drawn through the vacuum line and into the intake. This often results in a rich fuel mixture or even flooding. The next step is to check for leaking fuel injectors.
Install the fuel-pressure gauge, pressurize the system, turn the key off, and note the time it takes for a pressure drop of 20 psi to occur. If the time exceeds 20 minutes, you likely you have a faulty fuel-pump check valve or pressure regulator, or a leaking injector. To locate which part has failed, turn the key on for a few seconds to pressurize the fuel system and clamp the rubber portion of the supply line closed using a pair of clamping pliers.
Turn the key off and again note the time it takes for a reduction of 20 psi in fuel pressure to occur. If it takes longer than your previous measurement, the fuel-pump check valve has failed, and the pump will need to be replaced. If the times are similar, pressurize the fuel system again, but this time clamp the return line instead of the supply line.
