Car wont start with out ether runs rough
1991 305 TPI Z28 coupe. Started running rough after warmed up, then died while going down hyway after warmed up. will start again with ether after cooled down. Replaced : throttle position sensor , temp sensor, ignition control modual , fuel filter, ECU, maf sensor. Im going to sell it for parts ifg Ican't get it running.All these things I replaced are from tips on here. does any one know what causes this or is it oen of those things that might be 1 to 1000 different things?

Re: Car wont start with out ether runs rough
You've already sunk some dough and time into this. A little more might do the trick.
The ignition coil is cheap and easy to change. May want to give that a go. They can respond to heat soak when they start to fail.
It can't be that many things.
So just to be clear:
Cold it starts fine and runs fine. Then when it warms up it dies until cooled down again?
Before it did this was it running fine?

If your engine has TPI (Tunes Port Injection), you'll want to post this in a different section, or ask a Mod to move it for you. This section is for TBI (Throttle Body Injection) posts.

Put a scan tool, a compression tester, and a fuel pressure gauge on that thing, and find out what's actually wrong. Fix only the true problem.

Point being, diagnosis before parts replacement.

I'd check fuel pressure at the fuel filter under the car first, then ohm out the injectors if pressure is good. If pressure is not good at the fuel filter, then I'd suspect the fuel pump.
