So Ecu ended up being fine, I think I just didn't have it plugged in all the way. Changed the EFI relay and started right up. So I guess that was my problem all along.
So was checking signal to the ecu... now when I turn it on, then take the key out, the fuel pump stays running, and the cel is dimly lit. Also the cel does not come on anymore with the key on. So I'm thinking it's been a bad ecu all along? Unless I just created another problem lol
so for the past 4 months I've been having intermittent starting problems with my 93 sc400. I'll go to start it sometimes and it just won't fire up, no problem cranking. I can usually wait a day or so and it will fire up like nothing was ever wrong with it. Since last week I have had zero luck...
