'87 325is. I started having some issues last fall; the car would run fine & suddenly die at random, then restart no problem until November or so. Then one day leaving a g/f's place the car started, died, took forever to start again, and died 2 more times as I limped it home, where it has sat & has not started since. I have a winter beater so no biggie, but spring has sprung & I need to get my beloved e30 back on DD duty.
The car will turn over no problem, usually will catch for a few revs, then die and will not catch or start again. New battery, plugs, cap, rotor, coil, fuel pump relay, Fuel filter, main relay, CPS tested within spec, voltage to dme is good at the harness, continuity on all dme grounds is good as well. I do not hear the fuel pump(s?) running when the key is in the on position, or during the test in the bentley. Can someone tell me if I have 1 or 2 pumps? Build date 3/87. It's a weird car though, mid switch from early to late stuff I think. I used to be able to stomp test but my light for the check engine light burnt out, on the days off to fix list for now. The car also did not pass the tps switch test, particularly the wot switch portion of the test. The car used to throw a wot switch code when the cel
light was not burnt out but the car still ran & drove fairly well. I'm goin' to re-adjust it, but I don't see why the wot switch should have anything to do with just start & idle conditions. Side note, the car was pretty low on gas when I really had issues the last day I drove it in the fall, is it posssible that the fuel pump overheated or sucked some shit up from the bottom of the tank & burnt out? Anyone have some bright ideas where to continue my testing & troubleshooting?
