20 Most Recent 1991 Chevrolet Corvette Questions & Answers

I have a 1991 convertible Vette and I had a simular problem. The top would release from the deck, but only the driver's side latch would release on the deck lid. What I discovered is a small bracket that is held on by a retaining washer clip and the clip had come off. Went to the hardware store and bought a new one for $ .50 and remounted the bracket. The manual release for the deck is located behind each seat, pull towards the center of the car.

If you have good spark at the plugs then it is vacuum or fuel. 1 vac listen for hiss in the few min it runs check lines for damage, splits, unhooked etc. don't forget under car and dash 2 check fuel pressure, check for fuel delivery to the cyl. remove spark plug crank and check small look for fuel. remove coil wire so it won't start on you.

I hope this diagram is correct? At the relay, the relay has two sides, the load side carries voltage to the pump, that is the line that looks like it switches between D and E. The control side of relay is on the right, that side needs voltage and ground. The voltage comes from ecm, usually a green wire with white tracer. Did you check for voltage on that wire, engine cranking? Even though the fuel pump gets voltage through the oil pressure switch, does the vehicle start and run? If more than one problem, I'd have to check rpm signal and where applicable, security system. I was just curious, engine cranking, you have spark at the plugs and fuel injector pulse?

If there is not fuel going thru Fuel injectors, then it won't start. You can buy NOID lights at any auto store to connect to Fuel injectors to see if there is a problem with Fuel injector module. Here how the NOID lights look like:

You plug these into the connectors of Fuel Injectors to check during cranking. If there is light then your Fuel iinjectore Module is Good.
Then there is a problem with the Regulator. Here how it look like.

Try a full cooling system overhaul. completely flush the rad, check all hoses, frewh coolan of the appropriate type and to the correct concentratin. Bleed the system.check the thermostat is opening closig at the appropiate tem[erature and that the fan is running as fast as it should. The temp really should not ne that high I think. Also ensure the system is properly bled. If too much heat is generated your engine will die so it is important to deal with this issue

Your Vette is notorious for clogged fuel filters and or bad fuel pumps. I'm going to link a video to what i believe is the problem.

39 pounds is not enough. Make sure the regulator is good, check for injector resistance

No it won't do this. Vats is only for theft protection. But if you or they cut the wrong wire, that could kill anything. If you or they spliced wires, the A/C should still work.

In the bottom corner bumper area...if so try going in ram air inlet besides it ..I fought one and ended up going that way after wasting time

Very simple use a star key and loosen the two front bolts between the sun visor and windshield insert the key vertically (one on each side) next with same key loosen the back bolts above behind head (one on each side), and it comes right off. Sorry, I don't remember key size.

Take out the air vents first the screws that hold the dash are behind them. Careful to keep track of the screws you will notice they are of different sizes. I'm just giving you what I can recall it's been a while since I removed mine for servicing, Hope it helps.

Does it crank,Turn over? If not it probably is a problem called "heat soak".. the starter is hot just from engine heat and wil not function. If it cranks but will not start i would check to see if it is getting spark.. if not than check the IGN module in the distributer. Do not replace it until you have it checked, costly part, i think Orilly auto parts has a machine to check it.. Could also be a ign coil going bad.. (coil slight chance)
