Re: engine quit while driving,fuel pump not coming on
This has happend to me before. It could be one of two things:
1) Fuel pump fuse is out.
2) The brushes in the pump motor are becoming weak and have stopped in a spot where they are too worn to conduct.
1) check the fuse.
if that's not it, try this (it's worked for me and I was able to make it to the shop to get a new pump installed.)
2) Turn the ignition to the ON or RUN position, but be sure that the car is in park. Grab a rubber mallet and carefully get under the car (from the rear) and locate the fuel tank. Give the tank a few raps with a rubber mallet. This will jar the tank and hopefully break the brushes free from the 'dead' spot. if it works you will hear the pump begin to hum. Then drive it to the shop.

I think your fuel pump may have quit. To check it... have someone turn the key on until the dash lights come on while you get as close to the fuel tank as possible, Do Not Crank The Engine, Now... when the key is turned on... for about 2 seconds you should hear a whineing sound from your fuel tank. If you do now... your fuel pump has quit.
No. it wouldn't keep it from starting. If the engine cranks but won't start, probably gas or spark (ignition) related. Do you hear the fuel pump in the tank turn on for a couple of seconds, when turning key to on, not start? If you cannot hear the pump, better check if you are getting gas up to the engine. Maybe the fuel pump quit, or the pump circuit needs looked at. The pump should briefly turn on with key on to pressurize the fuel system-the fuel line and the fuel rail where the injectors are. Then the pump will turn off, and only come back on again when the engine is cranking, and stay on when running.
Correct fuel pressure is important for easy starting, and good engine performance. Have the fuel pressure checked against the specification for your vehicle. If fuel pressure is good, check the ignition system-check for spark.
Before starting the engine, the fuel pump should only run for a few seconds when the key is first turned, to pressurize the fuel system. Even though the pump appears to be running, you may either have not enough or too much pressure for the engine to keep running (fuel pump or pressure regulator). I think it may just be a coincidence the engine quit while turning a corner, but the gas in your tank may have been so low it sloshed away from what is likely a very old pump, starving it and causing it to failure.
You're either out of gas or you need a new fuel pump. Roll the keys back to the 'off' position. Have someone sit by the back tire and listen as you roll the key forward until the lights on the dash come on DO NOT CRANK THE ENGINE OVER.
If they hear the pump then you're out of gas, if they don't hear the pump your pump is likely burned up.
Turn the key to the ON position without starting the car You should hear the fuel pump running for 5 seconds to prime the fuel up to the engine so it can start. If no sound is coming from the fuel tank area which can be heard with the drivers door opened in a quite area the oil sending unit on the engine needs to be looked at. If its bad the fuel pump will not prime. If the oil sending unit is good the fuel pump is at fault instead Oil pressure to your engine achieves to close the circuit to this switch which the computer senses. When the oil pressure is up to normal standards the PCM shuts that circuit off and turns on the fuel pump relay
Does engine still crank? If so you have to check for Fuel, spark, compression. when your engine quit ..odds are good you lost one of these. check for fuel since modern electric fuel pumps stop working without any warning.You should be able to hear the pump momentarily when you first turn the key to "ON" If good check for spark, modern "coil pack" spark systems have a few weak links. if engine cranks and you have spark and you don't know how to check for fuel spray some starting fluid in your air inlet and see if it will start momentarily
my first guess would fuel pump have some turn the key in the on pos, while u stand buy fuel door must be quit around you you should hear a light humming sound coming from fuel tank area the humming is the fuel pump also check fuel pump relay in under hood fuse panel hope this helps
I see you say that you have a new fuel filter but did you try replacing the fuel pump??? If not you can check the fuel pump simply by turning the key to the ACC position (thats as far as you can turn the key WITHOUT starting the truck) listen by where you pump the gas in and try to hear a low sounding whine if you cant hear it then it could be your fuel pump is dead and needs a new one....or it might be going dead.
