No crank after manual swap

Hey guys, I've been chasing this problem on my 2000 360 for a bit now and could really use a hand. I am stocked up on food, cigars, and alcohol and will have most of the weekend to work on sorting this out and would like some additional ideas to try. For the past year and a half I pieced together/fabricated a manual conversion. When that was complete, I attempted to start the car and I got a no crank condition. Just silence. 360trev has been really helpful as we went through this and we tried multiple ecu flashes to make sure that is not the problem. As of now, the immobilizer is completely bypassed. The puzzling part is I really didn't do much with wiring. I know the car won't start as F1 if it doesn't register that the system is pressurized. I figured pulling the system and the TCU would bypass this with the manual ECU flash. Am I missing something? I'm led to believe that the no crank and no fuel pressure issue is connected.

Here is what I know:
- The brake switch is working
- The gas pedal and throttle bodies are working
- There is no fuel pressure
- Sometimes the check ok will illuminate on the dash, sometimes it won't
- There are no error codes in the ecus
- Everything in the swap appears to be working
- I checked almost all of the fuses and they are good
- I swapped the starter relay with a different relay
- The inertia switch is in place
- The clutch engages and disengages properly according to the diagnostic tool
- The rear grill and bumper are removed
- There was an issue where the decklid wouldn't register as closed on the cluster screen, but it appears to be working now
- I did not remove the F1 wiring harness, just the components
- I broke a small ground on the top rear of the engine. I soldered and heatshrunk a new one in
- The acceleration sensors got a little banged up as I forgot to remove them before attempting to pull the transmission

Things I did since the car last ran:
- Pulled the transmission to reseal the TOB for the swap
- Removed the front bumper to put in challenge grills
- Disassembled steering column to put in gated column trim and remove paddles
- Install a cat back exhaust
- Remove a couple extra speakers from the fast and furious stereo install



Things to try:
-Testing fuel pump with diagnostic tool if possible
-Different battery
-Checking the few fuses I haven't
-Changing important fuses regardless of how they look
-Break down in a drunken sobbing mess and plead with it
-Double check brake switch
-Sacrifice small animals to old pagan gods in hopes the car runs again
-Reinstall F1 power unit
-Check for power from starter

Anything else I should add to my list?

 

Immobilizer was the initial suspect and is completely bypassed

 

Thanks guys! I'll give that a shot in a few hours here

 

I did not. I did nothing with bypassing the TCU. Will jumping that connection have the same effect as grounding pin #42 on the large TCU harness?

 

No worries on the delay! I'm still at work anxiously awaiting going home and trying to start my car! [emoji28]

 

Well ****


I'll still try it anyways.

 

Much appreciated! At this point I'll try just about anything lol.

 

IT WORKED!!!!!!!! THANK YOU GUYS SO MUCH!

I grounded out pin #2!

 

It's easy enough to make one. I made a wire for it in 5 minutes. I'll create a better solution in the near future. Thanks again. I am beyond ecstatic the car is running again after a year and a half. Everything else worked perfectly.
