Re: HELP 1991 GMC Jimmy Lost electrical power to fuel pump
I would do a fuse check. Stuff that was working and now isn't but tests good points to open circuit somewhere. Fuse panel is a good start place. Fairly common for fuses to protect more things then what the panel label suggests. i.e. a blown headlight fuse might also supply the fuel pump relay control side.
Another thing to check is any fusible links. |
