Update- we now have power to EVERYTHING when the key is switched on. The pink wire in the starting/charging harness requires 12v + while the white wire comes from the coil and heads to tach. But, we still have yet to figure out why we don't get signal from distr through ICM to injectors to pulse.

Is the distributor assy for these motors the same as the automotive, with the exception of stainless hardware?

get an efi engine harness and your problems will be fixed :lolhit::funnypost:

Edit: I have an efi dist. if you need one

Lol, I've got the harness figured, I may take you up on that distributor....how much you want for it

pm me an offer

OK the harness, distrubtor, and mefi 3 all came off of a running motor. Intake and everything. The only thing that wasnt purchased was the starter charging system harness but I dont think that has anything to do with the injectors getting pulse. JMO. Any other Ideas?? I am bringing my boat over and maybe we can use mine to get some answers. I dont know. Thank you guys for all your replies so far. Please keep the advice coming.

the dist is a GM EST, but the module is marine specific and the dist is what tell the ECM to fire the injectors
