Hey r3vers-
Finished the wiring on my S50 swap tonight, stong crank, no sexy engine noisers.
External fuel pump isnt getting any power, according to the multimeter, haven't had a chance to check the internal one under the passenger seat, but there are no priming sounds while cranking, or at all. Also wasnt able to 'jump' the starter via fuel or main relay.
I tapped out with these conclusions tonight, hoping to hit it with a clear head in the morning.
Grounds seem to be good
+12.54v at-
Power block in engine bay
Harness
Fuse box
Starter
Alt
Main/Fuel pump relays -
Harness came from a known running obd1 e34, so they are assumed to be functional, although they arent 'clicking' upon startup.
ECU ground-
Haven't been able to source 318is ecu mounting brackets, or any model at all, so I have it grounded to the frame with some 18 gauge. Probably the first thing I'll check. A good ammount of searching yeilded people arguing that it did, and did not need to be grounded.
OBC lockout-
Previous owner of the e30 said he didnt enter any code or have any lockout issues, and neither have I. A few searches have reported that the obc resets when the battery is disconnected, which it was for the entire swap period.
I know there have been many m/s5x no start threads, but I havent been able to find anything conclusive, and if sounding like a noob is what it takes to get some feedback, sobe it :)
Thanks for your time guys
