I've got an 87 IROC that has an ignition switch issue. i can't get it to start or even crank. anyone have an idea/common problem for these cars? thanks :]

 

Has this just started? If so, you may have a starter wiring problem. Do you have power to things like the radio, lights etc?

 

Check the switch at the bottom of column by the brake pedal

 

I've tried that, it'll turn over and crank now. But won't stay. I'm thinking it could be a fuel system issue.

 

So now that it has a new fuel pump, new fuel filter, new opsu and all new fuses; it still won't start. Ideas?

 

What do you mean by "won't stay"? "Turn over" and "crank" is the same thing, does the engine start? Does it run when you turn the key to the start position, but it kills when you let go of the key? What if you keep the key in the start position once the engine is running, will the engine stay running? Don't worry, you won't harm the starter doing that. If that's what is happening, your ignition switch is either bad, or out of adjustment.

 

Dude, you are throwing parts at this thing.......slow down and find out what the problem is. The engine is cranking but not firing? Firing but not running? Running but stalling?

 

Gotta agree with ScottD slow down and find the exact problem. If not your replacing parts that don't really need replacing.
