Oh, it's that hole?! I have the old one there still, will replace with new one when retiming bank1, see below (bad picture, wasnt made to point that part out):

Thanks a lot guys! Error is likely timing though, just dont want to tear it down until I drove it a bit, see if other issues should be resolved. The engine never sounded this good, it's like classical music! Of course it could still leak coolant or oil, that's why I wanted to drive it a bit.
Decided to redo the whole job, I needed to retime the engine anyway, that's almost halfway there. Mostly because wanted to put in an original chain and an original guide (the big one). I can do this job now in my sleep! Amazing how much faster it goes for the second time.
Retimed the engine, it was probably 1-2mm off, now it's timed to perfection...however: the car now cranks but wont start. No error codes of any kind.
Everything should be functional like fuel pump etc, this car was running fine a week ago. Battery was disconnected during the job, I couldnt shortcut anything.
Any ideas what could be the issue? Perhaps something might got disconnected during the job, but not sure what. Using same camshaft sensors and they are connected.
Has somebody run into this after doing the TCGs?
Thanks!

Seems like something must be disconnected or not quite plugged in all the way somewhere. You must have triple checked everything?
Yeah I hate bending those brittle wiring harnesses up.
It has spark. That's good news I guess.
It could be only fuel/injector related, right? I didnt put back those PITA injector clips but doubt they matter, the two nuts pushing the cover down hard anyway.
Has to be injectors cause I didnt touch anything about the fuel pump.
I think I've identified the issue, not yet sure how to solve it:
The fuel pump not priming when cranking, I dont hear the relay clicking and the usual sound of it the pump. Removed the relay and jumpered it and the pump runs just fine. At this point I would have thought it's the relay, but I have the exact same type of relay for the heated window and switched them over. No luck, still not running. The two fuses (17 & 57) are fine.
So it's not the pump, not the relay...crankshaft sensor perhaps? Probably the only sensor I havent replaced in this car
As long as it's not a wire in a bundle of 300 wires I'm happy with any problems!
Thanks!

Thinking about it loud, I know the followings so far:
- fuel pump running if removed the relay and jumped the pins, so it's not the pump
- swapped relays with the one next to it, chances are low both of them being defective, likely not an issue with the relay
- relay doesn't click as it used to when I put ignition into pos. 2 and also not hearing the 1-2 sec priming sound from pump
- crankshaft sensor likely plays no role at this early on, thus I would rule it out at this point
This start sounding like a DME issue. Like the DME not sending power to the relay. I have no clue how to solve or even test that. Any ideas would be highly appreciated.
I was thinking the same thing and even was looking in my Bentley to see if they had any helpful troubleshooting tips. I couldn’t really discern anything helpful and would have to defer to a sharper mind :-).
That's very kind of you! Where is Timm when we need him?
I guess it is possible that I have two bad relays in the trunk, car was used in CA and probably never used window heating (other relay is for window heating). I hardly used it in winter either, but still unlikely.
Crankshaft sensor: it doesn't make sense that it plays any role in initial priming, but who knows, could be a possibility.
I will figure which pins to measure to see if DME sends signal (85 & 86 perhaps) so I can rule out relay entirely. Not like it matters much, it's a $6 part.
Guess I can start the car,just by jumping the relay and then cranking. Just should install a manual switch on the dashboard and problem solved, screw you DME we are going old school!
This is probably how Cyclops2 started out 5 years ago and just being ready to putting the car on the road. Been working on this car for 6 months now

Thanks Timm, always appreciate your comments!
Main DME relay: yes, checked and it's connected, not sure how to test the relay itself though. Anyway, ordered the followings:
- Main DME Relay
- Fuel Pump Relay
- Crankshaft Position Sensor
Will know more when they got here in a few days. Only DME and DME wiring left if not any of these three.
....and you have also checked all fuses in the fuse carrier as shown above?

EWS DME sync problem? Did you pull the battery with the key in the ignition? There have been issues in the past when people leave keys in the ignition and the battery dies. DME loses sync.

Oh I can't specifically remember what gets cut off. Maybe it's fuel? Someone has to remember. You would need software for that like INPA.

Could be fuel, I cant get INPA running via the 20 PIN connector for an unknown reason. Tried the DME-EWS synchronization with BMW Scanner but only got me an error message. Otherwise no error in DME or EWS modul, also tried an older key and made no difference.
Just got the new Crankshaft Position Sensor...turns out FCP has the wrong one listed for my car. BMW changed it on 2000/03...guess when my car was produced Waiting for the correct type (12141433264), this is the new model. The old one doesnt fit.
Also, the aftermarket relay they sell for the fuel pump has only 4 pins vs the original 5, so I rather returning it. Only thing I could replace so far was the DME main relay, made no difference.
I need to move closer to FCP or ECS to get this project moving faster
Finally got the parts, and now I have no idea how to proceed forward. Quick recap of the situation:
- after timing chain/guide upgrade the engine cranks but does not start
- pulled a spark plug and there is clearly spark
- when key going into pos 2 I dont hear the fuel pump relay clicking anymore and/or the fuel pump priming
- fuel pump starts when removing the relay and connecting the appropriate pins with a wire
Today I have replaced the followings:
- fuel pump relay
- DME main relay
- Crankshaft Position Sensor
Also did the re syncing of the DME-EWS with INPA, it went thru without any error message.
No DME or EWS error message or any other major error in modules
After the replacement of the above parts and resynching the symptom remained the same: crank with no start.
Also tried jumpering the fuel pump (keep it running) and then cranking, still no start.
So it seems I have two issues, somehow related:
- fuel pump relay not switching on
- even when switching on the pump manually, no combustion
And this is all started by something what I did during the TCG job.
I can of course start measuring fuel pressure but what'd be the point? Not like that would help starting the pump.
Any ideas would be highly appreciated cause I run out of them.
Thanks a lot!

I should add that I have a bet going on with colleague that I could get the car working before May 31st without taking it to a mechanic )
George, since it ran before the rework, obviously something occurred during that period.
check the TIS for fuel/DME feed:
https://www.newtis.info/tisv2/a/en/e...ngine2/bowkipk
It looks like the 30 amp fuse that feeds the DME relay and the fuel injectors is at F109, which is under
the passenger seat in the fuse carrier. Seems to be the common denominator in your issue. Let us know
how it works out.

Checked the fuses under the passenger seat, all have 12.6V on both ends, including F109. They are all original with the exception of F107.
I wonder if it's even possible to start the engine after manually starting the pump, got some EWS error message after doing it. Probably detects it as a tampering attempt and blocks the injectors. Cleared the code and didnt came back.
I still dont think the problem is injector related cause pump should be priming for a second or so before cranking and it doesn't do that anymore. At least I think it used to do that after a click of the relay.

Assumption is good fuel level? Had to say it, been there before, lol.
Have you tried fuel misting the intake and cranking, since you have spark? If it lights off, then the possible
loss of initiation is the DME on the DME relay and fuel pump relay circuit, both triggered after unloader relay/ignition/crank signal.
Since you tried firing it off with the pump relay wired, the DME should have cycled the injectors. Provided all fuses are good,
I suspect a DME fault, OR....loss of 12v feed to injectors while cranking, possibly from moving the harness during repair.
Time for some in depth checking of circuitry. You'll win the bet, for sure.
