1981 Corvette will not start unless ECM is un plugged from distributer.

My 1981 corvette occasionally will not start. If you unplug the computer, it will start and run. Replaced several ECM's, distributer terminal board, HEI module. Problem has been on going for over 1 year.

    my 81 sits in the garage practical all the time, when summer hits i take it out a few times, well the battery usually is dead so i replaced it with a new one and then i noticed my battery dash light is staying on after i turn the car off.Now the car just cranks over and will not start, first time this ever happened. Its a 350 engine with a 4 barrel quad jet carb. I put new plugs and wires on about 4 years ago but probably only put 600 miles on the car.I have no clue way now it wont start?

My 1981 corvette tach quite working how do I get working again?


1981 Corvette has an electical tachometer that is driven by impulses from the distributor. First, check for blown fuses, next make sure the tach wire is plugged into the distributor. Next bypass silver tach filter or capacitor located by manifold to see if the tach moves at all. If these steps do not reveal a change in tach operation, then the most obvious next step is to remove the tachometer and get a new board for the tachometer. Unscrew and remove cluster lens and then unscrew tach bezel, and gently pull out the tach noting position of insulators. I believe these boards are available still at local autoparts locations. Replace board, note position of insulators and reinstall tach, bezel and lens. Old corvette are cool and are pretty easy to work on! Should be fixed, enjoy!

1981 corvette when i turn my head lights on the knob starts getting hot?


Its either a short or the switch is defective. Remove switch from electrical connector and use an ohm meter to test their resistance.
If resistance is high replace switch.

1981 Corvette glass T-Top repair


Sure not a problem! I have a '76 Corvette. I use Mid America Motorworks. You may also want to search Ebay. I have purchased a lot of parts from both places, and have never been dissatisfied.

(I was a little skeptical about Ebay at first, but I dealt with those that have Ebay stores, checked their Seller rating, their Feedback score, and posted questions to them. Always got the part I wanted, and pretty darn fast!)

I bought my carpet set, and various steering components from Mid America Motorworks. They send me a catalog about two to three times a year. They have those T-Top gaskets sets for an '81 Corvette. Your Corvette is a C3 like mine.
