My truck will turn over but won't start

remove gas cap put ear close to filler tube and have someone turn on key listen for pump to turn on it will be a buzzing noise if you hear this then try replacing the fuel filter if there is no noise check the fuel pump fuse if the fuse is ok then replace the fuel pump

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.

Since it started with starting fluid, you have a fuel problem. This could be due to a failed fuel pump. When you turn your key to On, listen for your fuel pump. If you open the gas lid you can hear the fuel pump while someone turns the key to On. It should come on and pressurize the system. Once the fuel pressure has built up the pump cuts off. It is also possible that your fuel filter is clogged, your timing belt has failed, your crankshaft position sensor or camshaft position sensor have failed. If you have a Check Engine Light, get it scanned. This will help determine the problem.

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.

it could be ur fuel bump try just turning the key on to the run and wile doing that have someone listen for the fuel pump it should make a noise

prob the fuel pump going bad mine was doin the same thing b4 the pump died completely i changed it and its worked ever sence.to check if it is the pump the next time it dosent start have someone turn the key over dont crank the moter but turn it the hole way just b4 it starts to crank wile your lookin under the car and listen for the fuel pump to click if it dosent then thats the prob.

I would start by spraying starting fluid in the air filter. If it starts then you will know for sure it is a fuel problem. A way you can check the fuel pump is take off the gas cap. Have someone listen where the cap was. Turn the key to the on position and the person listening should hear the fuel pump run for about 5 seconds. If it doesn't run it could be the fuel pump relay which is under the hood on the driver side. You can swap it for the one next to it temporarily. But 98% of the time it is the fuel pump. You have to drop the fuel tank. It is held up by 2 straps. And the fuel pump is in the top of the tank. You have to turn a retainer ring half a turn to get the pump out. Be sure to get the filter on the new one really good. It will ruin the new pump the first time you start the car. It will **** up dirt off of the bottom of the tank.

Hope this helps you! Please vote! Thanks!

I, yes it could be the fuel pump. you should beable to hear it run for a few seconds after the key is turned to the run postion. Have someone listen at the gas cap wile you try to start the vech. Good luck

you need to have someone to be near the back of the van when you turn the key to listen for the sound that should be coming from the gas tank your fuel pump if you do not hear anything you fuel pump is out try these websites www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hands on a Haynes auto repair manual for your van wish you the best of luck Michigan Man.

Turn key forward listen for the fuel pump to pressurize if you don't here anything then your fuel pump needs replaced and it's in the tank.
