no spark or fuel on obd2 swap

[717bimmerboym3]

put an s50 in my 87is and have the harness hooked up, all relays have power, fuel pump runs, motor cranks but does not fire.i checked all my grounds and everything looks good. Dme is getting power as well. EWS is flashed out already as well. Wondering if the euro crank sensor is bad, is this tested the same as a obd1 in ohms? Any help is appreciated. thanks

Only sensor that car needs to start is crank sensor. All others can be bad, did you perhaps switch plugs or something?

On the OBD2 swap on an s50 you need a euro crank sensor that mounts on the front toothed wheel. I never had my harness off the motor so i didnt misplug it.

Im going to switch some relays off my m3 since its the same harness and see what happens and post what the outcome is.

Luckily the timing case has a spot for crank sensor

Ok so I checked some more things out and sprayed starter fluid in and it fired. So now i guess i need to check fuel pressure and see if one of the pumps is bad.

there you go;

now you know you have = spark

if swapping out one pump its a good time to do both

Ok so my pump outside the tank is bad. ordered both new pumps and a filter. While i was under the car I noticed my fuel hard lines were pretty rusty at some spots. Does anyone know where i can order some new lines? I was at my local u pull its a week ago and there were no e30's.

I think new ones come straight. And need to be bent
