82 GMC Sierra 92 model no fire to fuel pump


check power and ground at the pump electrical plug, then if one is missing then check at the pump relay under the hood for voltage and ground on the proper terminals.

1994 GMC Topkick not getting power from the fuel pump. Where is the fuel pump relay located?


Before going there, check your INERTIA SWITCH (INTERTIAL CUTOFF SWITCH). A small accident or a sharp bump can cause the cutoff switch to trip. The switch is located adjacent to the passenger side rear shock tower, and there is a pushbutton to reset (on most Topkick tucks). Carbureted Topkick trucks do not have cutoff switches, and some custom trucks have the inertia switch relocated.

1998 gmc c7500 topkick, replaced fuel pump but it's still not cranking and when it does, won't stay cranked. Like it's not getting fuel, any suggestions?


First, use test gauge to check for correct fuel pressure. Bad regulator could be the issue, or badly clogged fuel filter. Next, test ignition module.

Topkick cat 3116 wont start


Check your fusible links; these are small wires molded into the middle of a bigger wire they are usually located up by the battery cables. When they burn they become discolored and softly flexible. Also check your relays too.
