I don't know shit about M42's, but if this was a M20 I would think the coolant temp sensor or something that controls the mixture while the engine is cold. It seems like once it warms up and the O2 sensor takes over control of the mixture, everything is good. So you may have open loop issues.

For everyone reading, it was resolved page 11 -- blocked exhaust
It was a bit frustrating to read that you had all these critical components working (i.e. 'fuel is present') when critical tests werent verified (i.e. injectors pulled and verified to be sending fuel). I think you went down so many rabbit holes because of that. You definitely WERENT getting fuel to the spark and thats a critical component. That was figured out at like page 10 lol
Glad its working....
edit: whelp apparently you have a whole other issue. good luck.Last edited by jaredmac11; 09-08-2016, 04:44 PM.

In addition to the clogged cat, the 2 crank position sensors that had been tried were incorrect. So we got an additional known working m42 CPS sensor and it fired right up!
DONE.
Congrats! I've been reading and lurking, but I'm glad that you finally got it. How's the difference from how the engine was before?

I'm wondering if we had the same issue...

The one that made it all run was an OEM BMW sensor from a known running m42 with original equipment.
Do you know the part number? My car wouldn't start with new CPS with the part # 12141721504, which superseded the original.
I also bought a used OEM CPS (off ebay), part number 12141721968, that did work.
