hi i am having a problem with my 1989 corvette the car seems to start up fine but if you turn it off it turns over but it wont start this happens for about 2 mintues then if i wait and try it again it will start.. after starting it and running the car it feels like it is running on 7 cyinders . i have replaced the plugs wires distribution and distributor cap rotor E.C.M. and the fuel pump... the problem is still happening can any1 help or have any info on this problem it would really help me thank u

 

It could be anything from a bad plug or wire to a dead cylinder, etc. Did the car run okay before you did the tune up? I hate it when a car does this. To save money and blood, sweat, and tears, I would take it to a local Corvette speciality shop and have them diagnose the problem(s) specifically. Cheaper in the long run!

Good luck

 

Hi!!

HOw many miles on this bad boy? I am nt sure how easy it is do do on a Corvette (I am still working on getting my '90) but when it is running, (badly) can you take the plug wires off to see which one DOES NOT make a difference?

I am just thinking a bad injector or something....

 

As a variation to what the above poster said. To find a dead cylinder, I let the car cool down completely. Then, start it up and (carefully) check the exhaust manifold at each cylinder to see if they're all getting warm/hot. If one cylinder isn't firing, it'll be cool for awhile.

 

Check your fuel injectors!
