you will have to drop the fuel tank to get access to the pump.you will have to remove all gas and vapour lines as well as electrical wires(plugs)as you drop the tank.its best to do this job with as little fuel in the tank as possible.you will have to support the tank with a jack and remove the tank straps then lower the tank.remove the sending unit lock ring and remove the unit form the tank,then you can see how to replace the pump.
Yes, there is a Fuel Pump Relay. The Relay is located on the firewall just above the left-hand (even cyclinders) valve cover as viewed from the front of the car. There is also fuel pump test lead attached to the harness at the fuel pump relay. Attach a power wire from the battery to the lead and the fuel pump should come on. If fuel pump comes on, the relay could be bad. Also check the fuel filter located under the passenger side of the truck tucked into the frame rail.
according to advance website your fuel pump is electric and inside the tank. the only pre-filter is thus the screen around the pump inlet. years of detritus can collect around them, but you are going to have to lower the tank and pull it out to see. it is 20 years old and a replacement would be in order anyhow if it has never been changed before.
You need to replace the fuel filter every 30000 miles.The gas stations tanks are full of dirt. Also check the flow of the catalitic converter.Put your hand at the tail pipe while someone is pushing the gas petal down. The farther they push the petal the more exhaust should be coming out.
I hope this helps you
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.)
I'll tell ya what a diesel mechanic told me..."fuel injector pump". It seems that the new low sulfur diesel being sold now wears the seals out on the older pumps. I changed the fuel sending unit and that seemed to help a little, but now while driving it will shut down, and it's hard to start. Going to have the job done now. Part is very expensive! Hope this helps.
buy an aftermarket electric pump from Summit Racing and mount it on the frame rail right near the filter....do not waste time dropping gastanks and paying for ridiculous gm type in the tank pumps, the in the tank pump is a giant fock u to the public from the automakers.....remember the little mechanical cam driven two bolt cuteys? 15 bucks and 15 minutes and you were done.... thanks big three!
