I have replaced the fuel pump on my `96 Chevy Blazer T10 4 times now to finally get a Delco from Carquest, after them swapping 3 of the general ones out, and having me put a piggytail wiring harness on.(Waste of time, but hey, they were trying to ehlp me to.Now I have Installed the Delco Pump & fuel filter. Everything seems fine now, maybe a bad run was on the general pump. But now I notice that the RPMS kick up a couple of notches as though the accelerator is being pressed. Literally just idling up and down on it's own as it sits in park. Someone please help. Is this a fuel injector issue? Or am I back to the fuel pump issue?

Second issue... My lights were flickering until I took the drl fuse out of the glove box. This stopped the ticking going on from the glove box, and stopped my headlamps from having a dull flicker go on. I placed a new fuse in the drls place which caused the tick to occur again and the lights to flicker. I have taken the fuse out again for good. No ticking, no headlamp flicking. Will this be okay to leave out?

 

Wow! Sorry to hear about your bad run of fuel pumps. I guess that with the tank being disturbed so many times that a little dirt could have gone through to the injectors. You could always run a can of injector cleaner through the tank. It couldn't hurt....might help.

As far as I can tell, removing the drl fuse should just disable the drl lights and not create any other problems.

 

for a part that important it should be nothing but oem-delco
