You're using an adjustable regulator instead of a plain traditional one?
Main harness finished, MS3X harness partially installed. Communicated with ecu and datalogged while turning over the engine. Discovered I wired the TPS incorrectly. Will fix that tomorrow and start on the ignition coil wiring.
The dragstip is a personal challenge for me. Of course I am always interested in how I measure up but there are now enemies at the dragstrip. I am keenly interested in fast street cars of all makes and models.
Finished the wiring but no dice. Battery is dead and even with a charger the engine/starter draws too many amps. Voltage drops to 10.5 or lower. May not be enough to effectively fire the coils. Did verify that I have spark and fuel though.
So, buying a new battery Sunday and installing a fuel pressure gauge before trying again.
I beg to differ. While you were cobbling together a bunch of mismatched parts on your M car, I installed stand alone on the boosted E24. It lit right off and idled.
maybe its a e24 thing, my frankeninjection system worked on the first try, only bug was a starter relay that barfed right when it was time to try but a jumper wire got past that
for those that don't know its a red label 413 (3.3.1) from a m50tu on a modified 93-95 525 harness, completely hand built tone system for cam sensor and m30b35 balancer with the teeth shuffled around all installed on a m88/3

Installed a fuel pressure gauge which indicated no fuel pressure. Disconnected the return line at the regulator and switch the fuel pump on. Sure enough fuel poured out of the return line.
Smashed my thumb installing the new battery earlier so decided to call it a day. Will swap the lines at the fuel pump tomorrow. I think it might actually start.

One big thing Todd has going for him is the sensor check before start attempt and not having to stab a distributor trying to get the right the first time.
Having pulled my engine several times now to fix leaks (still absolutely leak free BTW) and install the distro....this last time I got it right the first time and it started right up.
