Ok, I'm new here. I've been using the H.A.M.B. because I'm more of a hot rodder, but it turns out my 350 TBI is too "nontraditional" for them to help me out.
So, here's my problem. I have a 1990 Chevy 350 TBI engine that I have put into a 1955 Chevy Panel Truck, and I think I'm having trouble with the computer. I have been searching all over google to figure this out, but have had no luck. Here's what's going on:
The engine cranks and has spark. I can force the engine to fire up by dumping fuel into the throttle body. Currently, my injectors are not firing. I have 12+ on one side of each injector, but I do not get the - pulse from the ECM. I can jump the wires at the ECM and force the injectors to fire, so I know there's nothing wrong with them.
So, from what I can tell, either my ECM is bad, or it's not receiving the signal it needs to fire the injectors. I have thought that it may be the pick-up coil, but I don't know how to test for that.
ANY HELP WOULD BE AWESOME!
