Is there a breaker or a fuse for the fuel pump and if so where do I locate it?

Inside the fuel tank. Check the fuse,relay, and is the security light on constant. Just things to consider before replacing a $200+ pump.

In the pictures above, I have the fuse layout for the fusebox under the hood of the vehicle (Believe its the same one you have on your video. I have marked with a red arrow the location of the fuse dealing with the fuel pump. Also marked with a yellow arrow is the location of the fuel pump relay. In the other picture I have is the location of the fuel pump cut off switch which is like a circuit breaker and where you see the arrow pointing down in that picture is the reset switch which you have to push down if that has popped in order to reset it. Hope this helps you....

The fuel pump is powered by a relay and a fuse. No circuit breakers.
The relay and fuse should be in the fuse box in the engine compartment.

Hello: It sounds like a fuse or circuit breaker problem.Please check the owners manual under (fuses). Locate Fuse panel(s) check all related fuses and breakers..F/PMP RLY.This is a good place to start.

these trucks came with a mechanical fuel pump located on the firewall in the engine compartment that works off vacume. its a cheap an relativly easy fix

if there is no power to the fuel pump check relays and fuses....UNDERHOOD FUSE & RELAY PANEL IDENTIFICATION Fig. 2: Underhood Fuse & Relay Panel Identification Courtesy of ISUZU MOTOR CO.

Underhood fuse block swap out relay #7 thats the ECM relay.
Ground Circuits Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location.

The electric fuel pump's operation on that vehicle is triggered by the powertrain control module, activated by a relay (likley located under the hood in the power distribution center, if not check the fire wall and underhood near the fenders) and protected by a fuse (the fuse is likely located in the fuse block that is under the dash, if not it will be under the hood in the power distribution center).

There is no internal breaker on your fuel pump. You will want to check your fuse boxes (one under the hood, one under the dash by the driver's legs) for the fuel pump fuse. Consult your manual or the key on the boxes themselves. If none of these resources are at your disposal, then you can buy a tool at the auto parts store that allowas you to test fuses without removing them. It is inexpensive and very well worth the cost.

Hope this helps,

relays are normally in the fuse panel on the left side of dash by knee.
