The fuse is actually a Relay Switch and its located in the Fuse Relay Center on the driverside of the engine compartment. The Black Box is labled Fuse Relay Center, the diagram on the cap displays which Relay is the Fuel Pump relay...the Relay switch is usually $8-$15 depending on where you shop

SOURCE: Fuel filter location Sierra

I have been told by a mechanic that the fuel filter is inside the fuel tank. Have to either drop the tank or remove the pickup bed. Access is on the top of the tank. This is poor engineering.

Under the hood in a black box. You sure it's fuel problem? Will it start if you spray carb. cleaner in the throtle body?? If it is a fuel problem, It's probly the pump.(in the tank.)

You might want to start by checking the fuses associated with your headlights. If those are fine, check the headlight relay. You can do a search online to see where the relay is located on your vehicle.

2000 gmc sierra the headlights wont come on unless i hit the steering column how do i fix this


The fuse is a good start. The headlight may also have a relay, which may be in another box similar to the fuse box. Check the fuse before the bulbs - it's more likely that a single fuse would blow, than both headlights blowing at once. the switch. Not sure where this is located on your car (dashboard? blinker column?) but that's another single point of failure that could explain both lights malfunctioning at once. check the fuses for the headlights, and the headlamp relay first. good-day !

My headlights will not come on everything else comes on but my head lights I can not find the fuse for them or could it be the circut breaker on the switch?


Look under the hood for the first fuse box, located on the driver's side. check the headlight relay it may be bad. all the relays are in this fuse box.

2001 GMC Sierra headlights won't come on. Located 3 each 10Amp fuses that were blown and replaced them, however, headlights didn't come on.


what fuses were blown and replaced? Theres a TBC fuse under the hood, along with a Headlamp Relay. Theres a R HDLP and LT HDLP fuses, make sure they are getting power, and are good. If the LT HDLP and RT HDLP fuses are good AND getting power, then the TBC fuse and the relay is good. then I would suspect the Hi-Lo dimmer switch bad. The LOW beam ground wire is YELLOW, the high beam ground is PURPLE. see if high beams work, if they do, then I suspect the dimmer switch is bad.
