86 325es. Got in it one morning and it didn't start. It was really low on fuel so I put about 6 gallons in it, but still nothing.
It cranks over like usual, but that's all it does. No sputtering or anything. I checked spark by grounding a spare plug on the valve cover and didn't see anything. I checked the fuel relay and I can definitely hear the pump running and fuel moving. I've tried replacing the relays with spares, all the fuses are fine.
I took out my performance chip and put the stock one back in. I've replaced the rotor and distributer with new ones I had. I tried a spare coil and that didn't do anything, as well as a spare ignition control module. I tried a spare fuel pressure regulator. I see no point in messing with the transfer fuel pump.
It has done this before during the summer, but after it sat for a couple days (i was too busy to work on it), it just started right up without me even touching anything. But this time I'm at a loss. It was after a pretty cold night, but not super cold. I've had no warning signs, and it always ran really smooth, so I'm at a loss. But I just remembered that I didn't check the CPS, but I doubt it's that. Anything else I'm forgetting?
