Hi there, I am Cam. Can you tell me if the security light is flashing? "
Did you happen to check for the actual fuel pressure?

Customer: replied 1 year ago.
Fuel pressure was 52 psi. The only flashing light is the red one on radio Dan

Ok Dan, do you have have a test light? If so can you see if there is power to the injectors?

Customer: replied 1 year ago.
No power to injectors. Fuse is good
Expert:  GM Tech (Cam) replied 1 year ago.

Does the fuse get power?

Customer: replied 1 year ago.
12 volts measured at fuse block
Expert:  GM Tech (Cam) replied 1 year ago.

Ok, so that means the wiring is bad. Can you jump 12V to the pink wire at one injector and see if that makes it run?

Customer: replied 1 year ago.
Will try first thing tomorrow. It's dark and cold here in St. Louis.
