Humm, please describe what you did on this. The ECU provides the ground for the injectors. You can not re-ground them.

Did you replace the injector O-rings, and upper and lower grommits???

Anytime you pull the injectors you must replace the grommits.

Have you adjusted the TPS, and checked th BAC valve yet?

 

I found a ground wire under the uim two black wires on a brass ring bolted to the engine.I ran a ground wire from where the black wires bolt down to the engine to the fire wall.Yes I replaced all the seals and grommits on the injectors.I adjusted the tps with my two light tester.I checked the bac with a battery to make shure I heard a click.I also cleaned it with some carb and choke cleaner.
