Sorry I couldnt get back to you sooner. Well no the check engine light doesnt come on and we took it to three machanice and they dont really know what it could be. One thinks it is the computer system and the other thinks it is the alarm wiring.

Hi:
Here is a how to for checking fuel pressure. It contains a video and also discusses checking the fuel pressure regulator which is easy to do.

http://www.2carpros.com/how_to/how_to_check_fuel_pressure.htm

As far as the security system, are you getting spark to the engine? Is it a factory alarm? Finally, is there a secruity light staying on?

NOTE: You will need a fuel pressure gauge. Most parts stores will lend or rent them to you. Let me know what you find.

No I dont think its a factory alarm. Iam pretty sure the owner before us installed it with someone. So this is what we did we checked the fuel pressure and it was ok. Then we took it to pep boys to see it they could find the problem but they couldnt diagnose the problem it passed all test and no codes or fire shoot were found. To them the truck was fine. I dont know what else to do

If I had to guess, I would say you have a bad crank sensor. It should have set an engine light, but it doesn't always happen. When they checked it, it may have been working properly. Thus, they found no problem.

I hate to say it, but this is one of those problems that is either a guessing game, or the vehicle is used until the problem gets bad enough to find. However, based on your discription, it could be a hazard if the engine dies while driving.

You may want to try replacing the crank sensor to see if that fixes the problem, but I am going from experience only. There is nothing indicating that is 100% the problem.

The crank sensor is near the harmonic balancer (bottom front of the engine). Make sure that hasn't already been replcaed. As far as the fuel system, it could be a weak fuel pump, regulator. Have you checked it? I believe I gave the directions in a prior posting.

I reviewed the entire post. Has the vehicle started since it died? If not, have you checked to see if you have spark and fuel to the engine?

Yeah the truck starts but then it dies. We never know when its going to die. It just happen the truck can be parked and turned on or while driving. Sometimes when it dies we need to wait about 5 to 20 min to start again but usually it start right back up like nothing. Everything else stays on like the air conditioning, radio, and lights. I dont know what it could be

It is hard to say without a check engine light. However, a crank sensor usually plays a role in this type of situation. What you need to do is check for spark and fuel to the engine when this happens and it doesn't restart right away. One will be missing. Once we know which one is missing, then we know what system to attack, ignition or fuel. Do you know how to check for both items?
