thanks jlevie, i couldnt find out where they went for the life of me.

but i did get it to crank, turned out it was a bad starter ground to the battery.

but my new problem is i have no fuel so im going to figure out if my fuel pump is bad or not today.

The sensors in the bell housing are not needed with an M20B25 engine. There will be two 3 pin connectors that branch off the engine harness a bit forward of the middle of the engine. One goes to the CPS and the other goes to the Cylinder ID sensor that comes from the #6 plug wire.

found out that the two plugs coming from my tranny are the crank position sensors for the 325e, i didnt know they changes the sensor to the front of the engine for the 325 i.

does this mean i can ignore the sensors on the trans?

ok so iv narrowed my problems down to the starter, the crank position sensor, and a plug that comes off my spark plug wiring.

1) starter. i have done a bunch of searching and looking through pics and im pretty sure i have everything hooked up correctly. it is a early (86 325e) starter, bolted to my single mass 1987 325i engine/fly wheel.

i have the main power cable from the battery distribution block connected to my starter on the large lug. then i have the thick red wire from my engine harness connected to the same lug. finally i have the black and yellow wire from right near the thick red wire plugged to the bottom tab of my starter. like so

and yes my large engine ground is grounded!

2) crank position sensor. this is pretty confusing. to make it simple WHERE DOES IT PLUG INTO?? it is a three prong plug that it needs to mate with and i have 2 on the engine harness. one branching from where my icv plug is and one branching from the little vacuum hose that goes to under my throttle ( looks like a J). i tryed both and nothing. pics would be great for this one

3) plug from spark plug harness. pretty simple, it comes from where all the plugs go onto my distributor. it is long and is also a three pronged plug, i just have no idea where it goes.


and on top of this all i have 2 plugs that are on my tranny ( i think one is a speed sensor or fly wheel sensor?) i have no place for these to go on my wiring harness.


i know its alot to read and understand but i just want my car to start :(

thanks guys
