m50b25, electricity problems

[Jondezii]

Hey all, first of all i gotta say that im already sorry for my bad english, but i couldnt find answer for my problem in our languange bimmerforums. Here we go.

I have this -90 316i e30, and i've swapped m50b25 with vanos from -94 e34 to there. And im not getting spark and my fuelpump aint starting. But the engine rolls fine when i turn the key.

I've done wiring like this:

Body - Wiring Harness

Black/white - Black/white
Black/white - Black/white
Green/violet - Green/violet
Brown/violet - Brown/violet
Green - Green
Brown - Grey
Blue - Blue
thin White/green - thin White/green
Brown/green - thin green
Black - Black
Black/yellow - Black/yellow
White/green - 2x White/green
Black/green - Black/green

And these i left unplugged

Wiring harness:
-White/violet
-Blue/yellow
-Blue/white
-Blue/black
-White/yellow
-Grey/violet
-Brown/grey
-Yellow/brown
-Red/white

Body:
-Black/white
-Red/yellow

My ecu and relays are fine and working, when i take the fuelpump relay off and put a little piece of a wire to right pins, fuelpump starts running.

My crankshaft sensor is also working, i guess ? tested it like this:


And my ignition coil wires, shows these number, do they seem right ?


There comes 2 black wires to near to the battery, under them are brown wire and brown/orange wire, and they goes to ground, right ?


Im begging for good tips and advices. The summer is coming and im losing my mind with this car:)

Yes brown wires in last pic are ground.

The connectors in the last pic are both part of the engine harness correct?
Pretty sure one of them is your dme power. It should be connected to the small battery post which gets power from the fusible link.

The other should be ground.

I would suggest you find the etm for the car your engine came out of and check all your connectors.

Checked, both of them should be grounded as they are.





Which one of these should be connected to crankshaft sensor connector ?
