hi there, i just finished a m52b28 swap on my 325i 87 and i got a problem on the battery terminal.if i connect the 2 wire from the e34 wiring harness,i got electric spark on the positif(red) connection on the battery.if i just plug the 2 wires from the fuse box(e30) everything is fine.i don't understand why it doesn't work when i connect the 2 wires from the e34 wiring harness(i tried to switch them but also doesn't work).can somebody help me with it please?

i finally finish to connect the wires in the good places.now i got a other problem.the fuel pump look like it doesn't work.when i try to start the car,no fuel come from the feed line hose to the injector.also i don't hear any ''click'' from the relay when i turn the key.sooi'm gonna change the relay and if it doesn't work it's probably the fuel pump -_-'

fine.my fuel pump is working.i have fuel going to the rail,voltage on coils(12-10v) but no fire on sparks plug? i tested if the coils pack making electric spark with a tester and nothing. i don't understand?and someone tell me because the crank position sensor(making 520 ohms) is fitted on the flywheel not on the damper can be a trouble.is that true?Last edited by babine810; 11-25-2014, 08:05 PM.
