So I bought a 1992 vert the first of Jan. It ran great and very strong. It has a Stage 1 cam, heads and intake. So about a month ago a started it up and back out the garage. I let it idle in the drive for a few minutes while I cleaned the garage up and it shut off on its own. When I went to start it again it was VERY hard to start and was missing really bad.
I'm not a mechanic but I can hold my own and I'm trying to keep costs down. So I started doing some research on line and talking to friends.
Found out the computer was fired (fuel pump wouldn't cycle off) so replaced it. Did some more research and checked for a bad ground. I also installed a fire wall ground and ran a separate ground from the negative of the battery to the computer just to be safe. No change.
So I started replacing the usual suspects.
TFI module
Ignition switch
New distributor and have timing at 14 degrees
Cap and rotor
Wires and plugs
No change. When the car starts its missing like crazy and once it gets warm it wont start unless it cools completely down.
So back to the drawing board. I found a "No start check" list on line and just ran through it. Everything checked good. So at this point I'm lost. I really don't wont to take this thing to a shop just to find out its something simple. Now I'm just pissed and don't know where to check next.
