Question about 2001 GMC Yukon

1 Answer

I think that the fuel pump for my 2001 yukon xl has failed. Should I take a chance on pulling one out of a junk yard car and is there a video on how to change or instructions? Is there a way to tell for sure that this is what is wrong and is there a way test a used one to see if it works without installing it?

The only true way to tell if its a fuel pump or not is with a fuel pressure test, you can rent the testing unit at auto zone, as far as getting one out of a salvage yard is, you get what you pay for and if it don't work your out your time and money for a junk yard part, on something like that you go new not used you stand a better chance of it working, as far as changing it, you know it in the tank right? Thats why you want to go new because you only want to do it once.

2001 Yukon XL. Went nose first into water filled ditch, up to the windshield. Changed the oil and purged water from cylinders. Electronics are all out of whack now. Also cant hear fuel pump when I turn the...

use a carpet blower and let it blow under the dash for a few days. this should have been the first thing done while doing the other repairs. it might need a ECM,BCM and some relays.
The faster you can them dried out the better the chance of getting it running. hope the ditch didn't have salt water in it, if so chances are grimm of getting it running again without major electrical repair ! carpet blower Google Search these work great for getting stuff dry in a hurry.

My GMC yukon XL 2001 engine runs after 4 times of cranking.

Try turning key to on only, not start, 2 or 3 times first then try to start. If it starts good first try, then I'd change my fuel filter & then have fuel pressure tested if fuel filter didn't help. You may be looking at a new pump, but lets do filter & test fuel pressure first.
