Question about 2001 GMC Jimmy
The truck attempt to start but will not turn over. The radio comes on and light are working, but the engine will not turnover. I was told my a neighbor that I was out of gas and since my gas gauge does not work correctly, I added gas to the tank and still she won't turnover. I'd like to identify the problem before taking her to a garage.
If your gas gauge isn't working.....and it's cranking but not turning over..... it's probably a fuel pump issue.
Jimmys are notorious for giving warning signs before the fuel pump goes out; i.e., gas gauge jumping sporadically from the top fuel line to below Empty in a split second, hearing a 'hum' sound when you turn the key to the on position but not cranking it over. Oddly enough, if you WERE hearing this before and do not hear it now...it's more than likely a safe bet that it's the fuel pump.
A decent pump is going to cost you about $350.00...and depending on the labor rates for mechanics where you live, you'll probably put about $550.00 into replacing it through a mechanic.
Or ...you could drop the tank and put it in yourself, if you're comfortable with it.
Have it hauled into a mechanic you trust and have it tested.
If it's not the pump....have them test the fuse up under the glove compartment...
Hope this helps.
I only offer this , because ironically enough.....I had the same problem.
I was hoping I'd get off lucky and just have to replace the fuse....
It was, indeed, my fuel pump.
But I couldn't complain.....that original pump lasted 12 years.
And.....the gas gauge worked properly :)

Just because the lights and radio come on does not mean you do not have a weak battery. Try charging your battery or getting a boost.

Testimonial: "Brian, thanks for you input, but it's been determined that the fuel pump went south. Thanks again for your suggestion."
If it is an automatic, It has to be in park before the engine will turn over.
If it is a standard transmission the clutch has to be fully engaged before it will turn over, There may be a clutch over ride switch on the dash.
The engine would still turn over with no gas, If you hear a click when you turn on the key , it is a starter problem. DJ

SOURCE: 2001 gmc jimmy not starting
Did they do a fuel pressure pressure test to determine that its fuel pump? And if so what was the p.s.i.?It should be around 55 to 60 p.s.i. a few pounds under 55 p.s.i. Pump needs replaced, Your shop should have chk. this when it was there the first time. Did they by chance chg. the fuel filter, that can hinder it from starting too.

I had the same problem. My gas gage would read full and as I drove the gage would read empty; even when I had a full tank of gas. All I had to do is buy a new gas cap... yes that is all! $15.00 and a day later the gas gage is fixed.
