Question about 1998 GMC Sierra

1 Answer

Fuel pump? maybe

1998 1500 Sierra 4x4
Truck was sluggish at times, now it won't start at all.I would listen for the noise in the fuel tank, however I have no muffler per say. I have dual straight pipes and well, as you can well imagine I can't hear much over that noise, to verify a sight whirring noise in my gas tank.
Any suggestions?
Also, I know I have to replace the ignition, the key is hard to turn and I have to push down on the key, in order for it to turn at all. Sometimes when I try to start the truck, I get absolutely nothing, I try it again and it starts.... well it used to. When I turn the key, and the starter has a miss.. should I check the starter or the timing?

    Thanks, will try that. I'm kinda hoping it's nothing more than a case of bad gas. My 08 Caliber SRT now has the check engine light on... filled up at the same gas station. Odd that the truck would not start at all though...

    It's not a spark problem, already verified. All spark plugs and wires were changed, maybe 3 months ago, long before this problem started. Battery is fine I had a short, but fixed that already.



    Thanks for the quick response!

    Alrighty, well it's not the fuel pump, nor is it the relay..... whirring confirmed and clicking in check....

    here's where it gets interesting, the positive battery terminal was shorting out, so while trying to troubleshoot that problem, seems now there is further damage to either the flywheel or starter motor.... ugh. Not a happy day. So I am done, its off to the mechanic with this beast. and if it's lucky I won't sell it for scrap!!

    Thank you very much, I guess it's what I get for asking for assistance from an over zealous person. Just refused to let up on the starter when it wouldn't go.... ugh!

    If it's just the starter than yaaaa!...... if not, well I'll deal with that when I get there.

    Again thank you for your comments!

Just turn key as far as run, and you should hear it. If no luck, spray WD-40 in throttle body intake, and try starting.If it fires up, it's a fuel problem, if not, check for spark.

    Not much consolation now, but I'm guessing just starter drive worn. Here's to hoping, Good Luck

GMC 2000 sierra pick up 1500 sounds like it wants to start but won't turn over. Battery sounds good so I guess battery and alternator are ok. For several years fuel gauge doesn't work and...


It sure could be. But, first...by "won't turn over" you do mean it cranks at normal speed but won't start?
A simple test of the fuel pump is to stand by tank and listen as someone turns key to on. When first turned to on, your pump will activate for 2 or 3 seconds, pressurizing the fuel system, and then shut off if the engine computer doesn't get a cranking signal. Do you hear it come on? If not, then something's not turning your pump on. If you can hear it buzz on briefly, then maybe it's your filter. Another test: Spray a little starting fluid into your intake manifold (remove the big hose going into intake manifold) while someone tries starting it.If it doesn't fire and try to stay running, then it's probably an ignition problem. But if it does fire off, then you know it's a fuel problem-likely your pump or filter. good luck.

Truck won't start but turns over. Gave the fuel tank two whacks with a hammer and it started right up. Do I need a new fuel pump? This is the second time this has happened, but four months in...


it might be the fuel pump, have someone turn the key on but not start it while you're under the gas tank and listen for the pump to pressurize, if you don't hear anything, you'll need a new fuel pump for sure, but the whacking it with a hammer is most likely a sign that some of the windings in the pump have gone bad.

My dodge dakota truck will not start. It has power we tried to pop the clutch too.


do you mean the truck won`t start and run or do you mean it won`t turn over with the key.if it won`t turn over with the key the you may have a starter problem.if you mean won`t start then it could be the fuel pump not working.with someone cranking the motor you should hear the fuel pump running with the gas cap off and listening at the filler neck.or hear it running listening under the truck at the gas tank.if you don`t hear it then you can hit the tack sharply with your hand or a rubber hammer,it hear the pump start to run then the fuel pump needs replacing.if not check the fuses under the dash and under the hood.if they are good then it may be the pump relay in the relay box under the hood and it should be marked on the box or lid.

REPLACE FUEL PUMP GMC 2002 SIERRa


the pump is in the gas tank siphon the gas out and remove the straps holding the tank(you will also need to remove the three screws holding the filler neck to the truck box under the filler door.)as you drop the tank you will also need to unplug the wiring to the top of the tank and the fuel lines they are usually plastic clips,but if this has been done before and the clips got broken from the first time they could have put clamps in place of the clips.I have found it much faster to remove the truck box itself and that way you don't have to drain the tank and it stays stationary while you RandR the pump with less chance of breaking anything.
Also did you double check the fuel pump relay under the hood in the relay box,I would start there first.
Hope this helps good luck.

Our 2002 gmc sierra 4x4 truck stopped while we were driving. Is there a fuel shut off switch somewhere that might have been engaged?


If its fuel related, it is most likely the fuel pump inside your tank. You can listen for it by having someone turn the key to on (not start) while you listen by the fuel tank. You should hear a buzzing sound for about 5 seconds. That means the pump is turning but is not really a good indication of pump pressure.
If you don't hear the pump run, I would check power to the pump first before you buy one. I think the whole tank unit is about $150.
Good luck

Truck just died need help!!!


Need to turn the key to the on position, and at the same time listen at the gas tank area for a hum sound for 3 seconds.. if you dont have that noise then you need to replace the fuel pump... in the future always keep your fuel level about 1/4 tank, that is what keeps the pump cooled...
