OBD1 S52 swap, has spark no injector pulse/fuel pump

[klodkrawler05]

Hey guys!

I'm having a bit of an issue sorting out the finishing touches on my e30 swap.

when cranking the car I get spark, however the fuel pump never primes or pumps and the injectors don't pulse.

I can manually relay/jump the fuel pump and get fuel to squirt out my lines and verify they are hooked up in the correct direction but when I hooked a scope up to the injectors I get no pulse.

Relevant specs:

87 325e
OBD1 harness from a 94 325is mtx car
OBD1 red lable 413 DME
TRM OBD1 S52 Chip
Wire 66 clipped at ecu to disable drive away signal.
S52 from a 97 m3 atx
obd1 intake manifold
obd1 sensors
brand new oem obd1 crank position sensor (scoped and verified it sends signal when cranking car)

I'm pretty stuck on this, originally I thought I was having the dreaded no start due to bad CPS however a new and verified good crank sensor didn't fix the issue and now I'm really running out of ideas.

Any help is greatly appreciated!

Thanks in advance,
Brad

bunch of views so far but no guesses as to a possible culprit?

For anyone who may be experiencing similar issues we finally got it fired up!

Turns out I did have spark and injector pulse but I was using the noid light wrong on the injectors.

The culprit was my e30 was supposed to have a low and high pressure fuel pump but it only had the low pressure pump, we seemed to be getting normal fuel pump operation but the car wouldn't run, hooking up a fuel psi gauge revealed 1-2psi of fuel at best, wired in a Holley Billet fuel pump and boom! 50psi and the car fired right up!
