Odd thing with my Omni fuel pump...
Hey TD, good to be back with a new Omni project. However, I need some help. I already reached out to another TD'r and we both are a little confused.
I have an 86 GLH, T1. I bought it a while back from a guy who bought it from a guy who bought it from a guy. You know the deal, basically, nobody knew anything about the car when I picked it up. I charged the battery and just for giggles tired to start it. She turned over strong but never tried to kick. So I checked the fuel rail and it was dry. With a little starting fluid she started and idled pretty well. Now, fast forward to recently. I finally got around to working on her again. I checked the fuel pump for power and had 11.2 volts at the plug but the fuel pump would never start. So I figured it was a bad pump and replaced it tonight. Verified the pump works by connecting it to the battery and it checks out. Plugged it into the hanger and turned the key and I get nothing. Since the car does run with starting fluid I do not think it could be the ASD relay issue. I checked continuity on the wires in the hanger just in case and they work, in fact, I checked voltage at the pump itself (in hanger, out of tank) and it had the 11 volts mentioned above. However, I had voltage on both red and black wire at the pump? And, I had voltage for longer than the 7 seconds that the car sends voltage to prime the fuel system (I think it is suppose to be 7 seconds, either way, I never lost voltage). I thought it may be a ground but if that is the case, I wouldn't get voltage at the connector, correct?
