Good morning gents. having a bit of an issue with my 91 318is (M42) and from what i gather this seems to be a somewhat common problem with our cars yet, as I searched through older threads on R3V and M42club I havent really found anything that is both a no crank and no fuel prime. most everyone has crank still therefore, here I am. detals below:
I came home late a week ago and there was a brush fire at my apts, Emergency personnel had the street blocked off so i was forced to park up the hill a ways facing down hill (my usual spot is a flat surface). I went the next day to move the car to my apt spot and no go.
1) At first the car cranked as if it was going to turn over then nothing. thought maybe my battery was drained, attempted to jump it and nothing. 2) I get ZERO engine crank and there is NO audible fuel pump prime at this time.
3) I check the relays: pulled the plastic firewall shroud off, switched the 2 orange 4pronge relays with each other and still nothing.
4) I attmepted to jump the fuel relay, front to back with a paperclip. when jumped and i turn the kep to on (KOIO) there is an audible fuel priming noise that is continuous until key is turned to off.
5) talked with some local SOCAL guys via the chat thread and suggested the following: tapping on fuel pump housing with blunt object and possible CPS replacement.
6) went to ecology and pulled a Cam and Crank position sensor from 91 318i donor, unknown condition (visiually looked in good shape) for $20 and yanked the relays as well.
7) tried just the relays, no change. replaced Cam sensor (since its easily reached) no change.
8 ) went to replace the Crank position sensor and came to find the allen head was rounded out (mind you i am now working on the car on the side of a busy street facing down hill, a bit nerve racking i'll admit).
as of this mornign there is still no change. I am utilizing a buddy of mine and my old Disco to pull the car up the hill to my flat parking spot so i can work on it there, and will be trying to hammer in a torx bit to remove the rounded allen and replacing the CPS.
my long winded question would be this: should i be suspecting the CPS or the actual fule pump (possibly in conjuction with the relays) to be the culprit? in my searching most guys have fixed their problem with the CPS, but not without already replacing the fule pump.
lastely, it can be noted that i ahve had the car for about 2 weeks now, and have not driven it often, maybe 5 times, and each time when starting it up, it seemed to crank over slowly... which almost leads me to believe it wasnt getting fuel quick enough (i methodically always turn ignition on to prime to pump and wait for dash lights to illuminate and go off) to ensure there "should be" enough fuel primed in the system. any and all help would be greatly appreciated gents; this issue caused me to miss out on Bimmerfest which was a bit upsetting. thanks again.
