Question about 2001 GMC Sierra Crew Cab

Noisy fuel pump

I recently replaced my fuel pump on my 2001 GMC Seirra 5.3 with a GMC replacement pump. Lately the pump seems to be "whining" rather loudly. My check engine light has been coming on and then going back off semi regular. The truck runs and idles fine until it's been driven for an extended period of time (an hour or more). After it's been driven and hot the pump seems to want to quit. The truck will stall and is very hard to get started again. It starts easily and runs good if the truck is cold, but once it's been driven for more than an hour or so it seems to act up again. Fuel filter was changed at the same time as pump, both have no more than 1000 miles on them. Any ideas???

Sounds like they need replace the pump again becuse if was good pump it would not do this.
This way amercain cars are not selling good all the jeeps have this dam problem to.
They put bad pump tell them do the job correct dig the paper work out man. Look up for better after market pump and make them do the labor becuse this one is trashed allready. Also leting your tank go below half tank shorts out all pumps faster and after market cleaners mess up the pumps and the gas liner inside i read isent that great

On my 2001 GMC jimmy sls,when the fuel guage gets near half full it drops to empty and lately when really full it reads empty until a few gallons are gone. What is the problem and how do I fix it?

you probably have a bad fuel level sensor in the fuel will have to remove the fuel tank to replace the sensor.the contacts on the sensor will break causing the fuel gauge to be can buy the sensor without having to buy the whole fuel pump assembly.

Truck won't start but sounds like it wants to

1. Take the air cleaner off and spray starting fluid in the intake for about two seconds.
2. Attempt to start the vehicle. If it runs on the starting fluid, you have a gas problem, if it doesn't, its spark.
3. Once you have determined which it is, you can repost for more specific information.
4. If its a gas problem, make sure it has good gas (fuel gage may have quit). When you go on the key, you should be able to hear the whining of the fuel pump cycle on, then stop. Have a helper go on the key, while you listen for the whine of the pump underneath. You should be able to locate the fuel pump and hear it if it is working. If the fuel pump is working, try changing the fuel filter.
5. If you have a spark problem, a likely culprit is the distributer, and rotor. These are fairly easy to replace. Its time for new spark plugs, wires, distributer rotor and cap if this wasn't done recently.

When idleling and accelerating my truck makes knocking noises a friend sugested it could be my lifters what do you think. My truck is a 1983 GMC Seirra 1500 just recently replaced radiator had a oil change...

The list your book gives you are all things that will cause a knocking noise. Only way to fix is to open her up. If you were having overheating issues before this happened then it could have damaged any of those except pump.

I have a 99 gmc seirra , we have replaced the starter, crank sensor, new battery, clean oil, and filter. The truck will turn over but will not fire. There seems to be no spark, there is gas at the fuel...

You need to hook a fuel pressure gauge to it. It has to have 55 psi or it won't run. Have you checked for spark at one of the plug wires. I'm guessing low fuel pressure, fuel pump.

A constant whizzing

that whining noise is definately your power steering pump. the earlier models eg 2001-2003 just have noisy ones. so they say, if that noise become really excessive; its an early warning that its gonna fail. the newer pumps are much quiter, but i was quoted approx 1200+ CND for a new pump. I have a 2003 cooper, and the whining noise is loud. only once has the steering been really stiff, but i resolve that problem by restarting the vehicle. watch out tho, the power sttering could fail on you while your driving around a corner, and if you dont have both hands on the wheel, you'll go strait.
