1981 Chevrolet Corvette - Page 2 - Answered Questions & Fixed issues

Ignition switch,bad fusible links, coil,ignition module. I have replaced several switches for this problem. At the coil, when you turn the switch on, there should be power. There also should be power when trying to start the engine. If there is no power while cranking, replace the switch. The reason it hits a cylinder or two is that the power goes to the coil, just not enough to get the engine running..

There is a pad on the engine passenger side by timing cover sticks out where head meets the block On that pad will be letters and numbers write them down ad you will be able to check in a GOOD shop manual it will tell you what you have. If it is original it is either a 350 or 427

If you are going to attempt this repair and have never done this level of work you had better buy a manual. It's not something that can be described here.

You need to have the choke adjusted so it runs on a fast idle so the engine can warm up or you may need the carb to be rebuild and adjusted properly.

Change the battery. Newer batteries sometimes go all at once, and are so dead even a jump start won't work. It has happened to me twice. Once you put in the new battery check the alt output with a volt meter should read about 14.5 volts at the battery. If it does problem solved just reset the clock, radio etc.

sounds like your on off switch in vichle is not working correctly as it may be stuck in the on position even though you switch it off. I say that only because there seems to be power on the light motor all the time and when you start the car they flip up> find the relay that goes to the motor off the lights it could also be that the relay is stuck in the on position. when you switch your lights on you should hear a click noise come from the relay if you dont then it is possible that it may be burnt inside> easy way to cheack is to start the car and remove one fuse at a time if nothing happens replace the fuse and do the next one until the lights close. all you will be doing is removing power off the relay, when you find the one that is powering that motor remove it and replace the relay

unfortunately vehicle owners refer to vehicle parts using names that they make up as a dolacky or thingabob. If you can explain where this valve is located maybe some can help.

you don't, it either works or does'nt, check all grounds, put power to it (12) volts, sending units are very delicate, care must be taken when replacing, in tank, . a wire diagram would show you the power wire, the ground wire, etc., maybe you can check it ?

your solenoid may be bad or check the coil.

Check vacuum hose from modulator back up to Manifold then check vacuum on the manifold. The slightest leak will cause transmission problems. I replaced those hoses the problem was solved.
