Suspicious sporadic start
I don't know why it would start one time and not the next. Is it possible that it being immobilized? I don't know at this point. Can I get some of yous to help? I would really appreciate it. Thanks. And I have videos of it idling and pictures of the codes I pulled if that would help ya. |

Crank fuel no spark hints at EWS so scan for EWS.
No start intermittent suggests crank position sensor. (and may also inhibit spark).

Can you clarify what EWS is? And with CPS? It never showed up on the scan. Could it still be a possible culprit? And which CPS should I change or check? There's two of them.

CPS is cam position sensor and I'm not sure that will prevent a start, the car I think has a workaround for the CPS not working.
Crank sensor is CPK for some reason. I'm pretty sure the car won't allow spark until it knows where the crank is. EWS stands for D rive A way P rotection. (Whatever the three words in German). Aka immobilizer. The "catch22" is that you won't get a code until you get a start from my understanding. But look into immobilizer, because it comes up on the forum regularly the EWS gets out of sync and allows crank but no start (why allows crank the world may never know)

Can we check fuel pressure? How many miles on it? How much fuel is in the tank?
No spark is a biggie. Remove and clean the cam position sensors. Check the wiring harness. Wiggle the harness while someone cranks it.

Yes there's fuel in the tank. I have 15X,XXX miles on it. I just replaced the tb and maf sensor.

Cam sensors are right on the front of the engine. The crank sensor is usually near the bell housing for the transmission. I've never changed on M62 not sure exactly where it is.
