The only thing else i can think of, which i highly doubt is the distributor and the ignition pick up. However i took the distributor...

    Yes i know the computer doesnt control the reverse lights but because the wiring is for a aod transmission that was originally in the car i dont think it uses the same wiring for a t5 tranny,but not sure. I know where the switch is but the previous owner cut the harness off which i couldnt...

    thanks guys, i appreciate the detailed replies! It helps a lot! I am gonna replace the tfi module on the distributor as that was my initial though being the ignition, because it doesnt seem like a fuel problem and it breaks up a little when driving so ignition is my my first thought. I had to...

    I put my new exhaust on and it sounds pretty good but i have a pretty loud leak where the x-pipe meets the header. I have tried numerous times to adjust and correct it but doesnt seem to want to line up properly. Is there a form of a gasket maker i can use to try and seal it up a little better...

    replaced ignition switch..Still no start?

    So the kid who owned before me had the car hooked up to a rocker switch to start the car. The switch went directly to the battery and the starter solenoid, which means you can crank the motor even if the key is not on run. In order to start it you turn the key to the run position and use the...
