Question about 2001 GMC Jimmy

2001 GMC Jimmy wont start

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.

Try pouring a little gas into the throttle body and starting. If it runs and dies, most likely a bad fuel pump. I already had to put two of them on my 1998 jimmy. Good luck!

    Thanks Michael, you are correct in that the fuel pump went bad. My fuel gage did not work properly and I have tried to make sure the fuel level never went below a quarter tank. Well, last week, coming home from work, it was raining buckets and I did not want to stop for gas knowing it was getting low. Well you can guess what happend.

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 :)

    If your vehicle is cranking but won't turn over, but everything else is working fine, I'd say check the fuel pump.

    You say your gas gauge isn't working.....how long has it not worked?

    Did it jump sporadically from full to empty before quitting completely?

    Jimmys, and most other vehicles, are notorious for giving the warning signs before a fuel pump goes out; i.e., gas gauge jumping all over the place and/or not working at all, turning the key to the 'on' position and hearing a hum or draw before turning it completely over. These are just a couple signs that the fuel pump is going out.

    If such is the case, a decent fuel pump will run you about $350.00 and, depending on labor rates of mechanics where you live, it could run you about $550 to $600.00 to replace it - Unless you're comfortable with pulling the tank and doing it yourself.

    A bad distributor or control module in the distributor, or even a solenoid issue can cause the same problem.

    But since you said the gas gauge isn't working "Correctly", I'm thinking it's likely a fuel pump issue for the reasons I gave above.



    I only offer this answer as I had the same issue in my 2001 Jimmy. The gas gauge was jumping all over the place, hearing the hum when I'd turn the key on...and one day, it just said, "Nope...not happening anymore." I was hoping to get lucky by it maybe being a fuse issue or something small, but it was my fuel pump.

    I won't complain though, because the original I had in mine lasted for 12 years.....the original AC Delco :)

    Once I replaced it, the gas gauge started working properly again and the hum prior to starting disappeared.

    Have it towed to a mechanic you trust and have them test it.

    It's better to pay for that one hours' labor to have them properly diagnose it than to spend hundreds of dollars on guessing or by going what someone else says they think it might be.



    Hope this helps....

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.

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.

SOURCE: gas gauge not woking properly gas tank only accepts a little gas

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.

My jimmy 2001 wont start it does after a few tries wondering is it my security system


Make sure the transmission gear selector is in the Park position, before attempting to start your Jimmy.
I don't believe the problem lies with in your security system.
Make sure the negative and positive cables are firmly attached to your Jimmy's battery, and also the contact's on the starter motor's solenoid, which you should be able to see by lifting up the splash shield on the passenger side, front of your Jimmy.
If none of the solutions above don't work then the problem is probably due to the battery in your Jimmy not having a very high charge level.

Radio and lights work but wont start


If the engine does not turn over, check fuses, wires, all in the starting system. If that all checks out, check the starter, a lot of parts stores will check starter for you if you take starter off and take it in to them.

2001 GMC Jimmy with a 4.3L V6 auto trans. Will not turn over


The starter relay may have a bad connection, this is where your battery connects, and a power wire runs to the starter, also these have a ignition wire which is approx 14-16 gauge wire. The relay could be cracked or the contacts inside are going bad. But the other is the neutral safety switch that you mention. I would check these first.
