e30 with M50tu Turbo : No fuel/no spark

[Oz10]

Looks like I need some help from you 24v gurus again!

My m50 turbo recently stopped starting and I'm trying to figure out what is causing it.

Info on the car:
Engine is a 94 m50tu
Fuel pump is a walbro 255
Its a drift car so most non-essential wiring is no longer used.

The Good:

I believe my DME is good, I've tried two and neither made a difference.
My DME is receiving power/ground on all of the right pins
My Crank Position Sensor is brand new
My main relay is receiving power and seems to be working correctly
The ICV buzzes when the car is switched on
My fuel pump is good (It turns on when we give it 12v)

The Bad:
The fuel pump is not priming like it used to.
The fuel pump relay is not receiving power from the DME. Because if this I do not have power at the fuel pump fuse or the fuel pump itself.
I also do not have spark.

I've seen a few threads where the ignition switch seemed to be the issue. However, I no longer have a stock ignition as mine is on an on/off switch.

I really appreciate your help! I've got an event Saturday and I'm running out of ideas!

My Crank Position Sensor is brand new

Brand new CPS's have been known to fail. Especially aftermarket ones. I'd check your fuses and revisit CPS.

I hope that wouldn't be the case, but I'll check the resistance on it. The old one looked like a wire may have frayed so I replaced it with the new one this morning and it didn't seem to make a difference.

I think we have found the issue. I've got about 4-5 harness wires all damaged right near the dme connector.

We're going to replace them and I've got a feeling that will fix our problem!
