No power at fuel pump chev.S-10 looking for fuel pump relay and fuse

You have to take off the passenger side knee bolster for the relay. From the trans tunnel to the door- Fog lamp relay-Courtesy Lamp Relay----Fuel Pump #1 Relay-Horn Relay-Rear Defogger Relay. Fuse is located in the Main Fuse Block Located on the right side of the dash (small panel pops off the far right side) passenger door needs to be open to do this. The fuse is labeled FP 1 and is the furthest fuse left on the second row from the bottom Red 10 amp. Fuel pump is located under the fuel door in the back of the car- you just need to take the door off and you can check for voltages or even replace the pump from there- no need to drop the tank or anything .

fuel pump fuse is located under the dash on the driver's side. Look for THIS -



The fuel pump relay is located underneath the dash, driver's side, up behind the metal panel (behind the plastic kick panel). It is NOT plugged into the fuse panel.




See #18 in this diagram -

It is under the Hood, in the Fuse Box. Go to this web site and put in your information and you will see the diagram

Which fuel pump relay fuse are you looking for? The primary relay fuse or the secondary relay fuse?
The Primary fuse is fuse #13 (10 Amp) located in the junction block.
The secondary fuse is fuse "G" (40 Amp) in the underhood fuse and relay center.

BOTH of these fuses can be checked by checking for power at the relay. If the relay has power where it is supposed to have power, then the fuses are not blown - there would be no need in this case to actually locate the fuses.

Where's The Fuse?

What Else Could Be Wrong?

check all ur fuses for continuity first, then u can also try to swap out ur fuel pump relay with another relay that looks jus like it, be sure to use a relay like for ur horn or ac relay something that wont affect necessary or direct engine circuits like for ex. an ecm fuse or bcm fuse. if fuses r good an swappin relays wont work, next is to trace bak from fuel pump ur wires an possibly keep back probing to see if u have a broken wire from relay box to pump . good luck hope this was helpful . in ur fusebox ur fuelpump fuse should b labeled or easily found in fuse box legend, most likely on bak of fusebox cover....

The fuse you are looking for is behind the plastic cover on the firewall on the right side. It may be a little disguised in a fuse holder. It is very near the battery junction box pins and fuse links. It's a 10 amp fuse and it supplies power to the relay for the fuel pump.

Got to figure why you have no power at that relay. Has to be an open wire or blown fuse to the fuel pump or something preventing it from getting power. Have to trace it back to where you find the problem. Check fuses first.

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 fuel pump is located in the fuel tank. On these GM cars, the fuel tank must be dropped in order to change the pump. It is alos recomended that the fuel filter be changed at the same time which is on the frame of the vehicle, left side. the pump at autozone runs about $75 and don't forget the strainer for about $10. The filter runs about$10 also.

The fuel pump relay is located under the hood in the "other" fuse box that has the more engine related fuses & relays in it. Look at the back side of the cover for the locations of these items. Sometimes you can temporarily swap 2 of the same relays to verify or /find and fix the faulty part.

Good Luck!
