Sounds like either the ignition module or the coil.

2. Are you getting spark when its not starting? If not is could be the coil or the ignition module.
3. Dose it seem not start more often when hot?
4. Have you had it die while driving?


1. I hear it prime when it starts and works. When it doesnt work it doesnt prime. Sometimes when it primes it turns over and starts and the idle slowly falls until it stops (about a 4 second process)
2. Yes.
3. I havent noticed it if it does but am curious to know.
4. No.

Sounds like the fuel pump from what you are describing.

Fuel pump was replaced when this was happening with a 255lph Walbro.

Replaced:

Fuel Pump
ECU (p28 to a 072 both obd-1)
Distributor
Main Relay
Fuel Filter

From what I gather, there is no fuel pump relay or fuse for a 90 hatch. If there is, I am missing it if its not part of what the main relay does.

Never Mind. I dont know what that 4 blade relay is behind the hood release, but there is an even bigger relay in that area and I took it out and it smelt burnt. I am assuming THAT is my main relay...
