Hi guys
I'm normally a 145 guy but I'm helping a friend try & start his 745. We have spark & fuel [will check pressure tom.],the timing belt is intact & It cranks well. The crank sensor wire is cracked[any way to check it?] I get a pulsating signal on my logic probe at the injectors. Checked the maf hose for leaks-Ok I put a little fuel in the maf hose & after a little time to evap. the engine ran momentarily. I disconnected the cts to induce a rich start-made no difference. The ecu has codes 123,121,& 312 in it Any ideas?

Thanks for your help.

Mike M.
