1990 Deville - No power to fuel injectors
The car ran and drove fine. It had good fuel pressure. Now it is not getting any power to the fuel injectors.
The noid light will not light on any cylinder. Fuses in the fuse panel are good. Fuse behind passenger kick panel is good. Any ideas? Thanks, John

wiring intact, and not burned or anything right?
did the DeVille have a relay for injector power as well, or just fuel pump? you could try splicing in a jumper and see if the vehicles fires. maybe an ECM issue?

Re: 1990 Deville - No power to fuel injectors
Is there 12v to the injectors, the noid lite doesn't check power it checks pulse generated by the pcm pulsing the injectors. If you have 12v, then it is possible a stated the module is bad but there is a definitive check procedure for this.

Can you pull the codes by simultaneously pressing down OFF and WARMER on the climate control while the key is in the ON position? If codes come up can you find them here?
