Just got done putting an e34 525i M50 into my 86ES (prod. 11/85). Wired it up, and tried to turn it to ON. Nothing. No power to fuel pump, any lights, no blower, anything. Parking lights do come on though.
Checked all the power wires, alternator has the big wire to starter and smaller wire hooked up, starter has 2 bigger gauge wires and two smaller wires both on bottom post, and those go up to the terminal at the passenger side. The fuse box is getting power to all but a few fuses, and of course those are the ones to fuel pump, and windows/etc. I tried flipping wires around on the stater and whatnot, but to no avail, and I suppose its a moot point since the car isn't getting power itself. Fuseable link looks good and un popped. Fuel pump will prime when jumped, and the car did run fine minus some bad vacuum leaks with the m20.
Cliff notes :
Car ran okay before swap, minus the typical dripping oil pan and leaks.
Did M50 swap into the car
Used brand new battery, hooked power wires up
No power to car, no hvac controls, no cluster lights
Did not touch anything in ignition, car does nothing when turned to acc/on/start
Fuel pump
Any ideas? I know this is kind of vauge, and any questions concerning details will be answered. I just don't understand why there's no power to anything. Thanks for any help!
