pleese help urgent

try changing the coil

how about instead of bump, you post the results of what people are suggesting, and/ or what you have already tried? you'll only get as much help as you provide.

check the air sensor off the intake, i had problems with that

we checked all your suggestions and sofar nothin but thanx for all you help well keep working on it

sounds like either the mass air sensor or a big vaccuum leak

Master problem with this may be the Computer. See if you can get one from a junk yard and swap it. Just my shot at it with all of the other suggestions. Just remember it takes fuel fire and air to begin combustion. If you dont get one of these elements, and get them on time, the cycle is broken and the chain stops.

check fuel pump pressure
and or make sure the ground on the rear end of the frame is on it grounds the pump. its always something stupid if it ran before it was taken apart it should run back together ECU problems are not very common so check the siple stuff first

problems ive had in the past to check on yours....
fuel pump , is it pumping fuel ?
spark, are your plugs good and have good connections ?
coil, is it grounded good and tight ?
cold start injector, is it opening to allow fuel into the intake ?
mass air flow sensor, is it mounted right and plugged in ?
vaccum hoses, they look gay but they almost all HAVE to be plugged in or it WILL NOT idle
ECU, i actually had my computer go bad on me, put a used one in and works perfectly, if its none of those... good luck, cuz it almost cant be anything else, try all the big fuses in the box under the hood, or the main engine fuse, good luck !

check the fuel pump relay. it might kick the pump on to build up pressure but the part that keeps it running when the truck is started might be bad. i know mine does not kick on when i turn the key but when i crank it, it builds up pressure and stays on. i had all kinds of problems with my fuel pump in my fuel cell. but def check the relay.

My bet would be on the fuel pressure, if it's fuel injected (i don't know if it is?) put a fuel pressure guage on the fuel rail and see if it's got enough fuel pressure?
