How do I fix my truck not starting?

FUEL PUMP ONLY HUM'S FOR 2 SECONDS WHEN YOU TURN KEY TO ON, NOT START, POSITION. YOU CANNOT HEAR PUMP RUN WHEN CAR IS RUNNING ! THIS 2 SEC., IS THE PUMP PRIMING ITSELF TO START ENGINE. YOU MIGHT BE HEARING EITHER THE POWER STEERING OR WHATEVER, NOT THE FUEL PUMP!!!!!! GIVEN THE YEAR OF THIS CAR, YOUR FUEL PUMP COULD BE BAD, CHECK FUSES, RELAY, GROUND WIRES, TO PUMP, ALSO CHANGE YOUR FUEL FILTER !!!!! AIR FILTER ALSO !!!!!!! SPARK PLUG WIRES SHOULD ALSO BE REPLACED !!!!

Try start the car again when it is completely dry, if it starts the rain may be short circuiting something on the loom in the engine bay.

If it still wont start,

will it turn over? (car tries to start)
- If it wont turn over the battery would be dead

- If it turns over but wont burst into life then we can go from there ^_^

You need 3 things for your vehicle to start and run.. Fuel, spark and air. If you've recently replaced the fuel filter I'd have the fuel pumps electrical connections checked out. It could possibly be on its way out. Also check all spark plugs, wires and coil pack to make sure nothing is damaged on the "spark system". Then of course make sure the filter is clean and that all of your sensors monitoring the air flow into the throttle body are connected. From personal experience though, I'd say it sound like the fuel pump isn't always doing what it should upon initial start up and that's where I'd direct my attention.

your truck is running too rich with fuel if you have a carburator have it check

If this is a sudden occurrence and nothing suspicious happened prior, you most likely lost either gas or spark to the engine. You need to check for both.

Do you hear the fuel pump in the gas tank buzz on for a couple of seconds when you turn the ignition key to ON? Unless the fuel pump turns on and puts gas under high pressure at the fuel injectors, the engine cylinders won't get gas to start. Correct fuel pressure is crucial to know if you have a fuel pump (or fuel filter) problem. If the pressure is correct, it is probably not a fuel problem but a spark problem, although there are less common instances where a fuel injector circuit may malfunction.

The ignition system not producing spark at the spark plugs is the other common problem of no starts. Buy a cheap spark tester at a parts store, plug it into one of your spark plug wires, then crank the engine over and watch for a strong blue spark. You might need a helper to do this. If you see a consistent spark, the ignition system is probably good, although you should probably check more than just one plug wire-sometimes one bad ignition coil in a coil pack will cause no starting. Good luck.

Are the plugs wet with fuel?
Check for spark. No spark? it may be the ignition module.

Plugs dry and spark present? No fuel?Spray a little starting fluid and see if it will run on that.
Then check pump fuses and for fuel pump noise.

Have you checked for spark first? Sometimes a car won't start due to no spark. This condition is usually caused by: Security system, bad ignition module, crankshaft sensor, camshaft sensor. You check it by pulling a plug wire and putting a screwdriver in the wire to see if it arcs. If it is getting fire look for the fuel pressure release valve usually located on the fuel rail, looks like a tire valve stem. If it shoots out gas, and you hear the fuel pump prime, check the fuel pressure regulator. It could also be the timing. There are four things needed for a car to start: fuel, spark, timing, compression. As for your question, as far as I know there is one fuel pump, you have to drop the tank to fix it. Hope this helps.

Have you checked the fuel pump and fuel filter? The filter might clogged not allowing gas into the engine. The pump might be bad so you're engine won't be getting any gas there either. Both of those are cheap and easy home fixes as well.

the filter on fuel pump might be clogged as well or fuel pump needs replaced

Sounds like bad distributor cap or rotor. If ones bad, might as well change both. Take off the cap and if there is a black color on the ends of the prongs, or on the end of the rotor, time to replace. Is it getting fuel into motor?
