Did your check to make sure your battery is getting as full charge??? If your voltage drops under 10 volts, your PCM will shut down your engine via fuel injectors and weak fuel pressure from low voltage to the fuel pump.:eek:

Post back and keep up the great work.

had the truck towed to my mechanic shop and its not the fuel pump nor is the fuel filter clogged. he said its a electrical problem, since its been raining nonstop. me and my dad checked the fuses the day after, we noticed one of the fuses was jumpy and making noise so we replaced it and still nothing. Mechanic said might need to replace whole fuse box, from excess rain in the fuse box.

I have heard of other owners having fuse block problems, corrosion if I recall.

What often works is a product that displaces moisture, CRC makes a product you can spray on the electrical components and it will displace moisture, so does AMSOIL MP. Had a Furd truck once at work that was very difficult to start when damp out. Someone at the Furd dealer suggested spraying the spark plugs etc with the CRC stuff and see what happened. So I bought a can of the CRC spray, sprayed everything under the hood and the truck started right up and ran like new.
