Well it will start  for about one second if you hold your foot to the floor(leaving th ethrottle body open without flooding it) and then just bog down and stall.

try the asd relay (auto shut down relay) there like 50 bucks from auto zone, its the asd and fuel pump relay together. or crank sensor, or the last thing it could be is the hall effect sensor under the dist. cap under the rotor.

Thanks but if that relay was bad the fuel pump wouldnt kick on right?? Well I can hear the fuel pump kick on and then shut off after the three seconds or whatever. Already replaced the crank sensor. Not sure ont hat hall effect sensor. Lol. Never heard of it.

Throttle Positioning Sensor is worth a try.  Best thing to do is to start a list and start replacing things. It really sounds like the coil pack, or something along those lines cuz it bogs and stalls, but I'm no mechanic. U said u replaced the IAC right?

try the pick up coil, under the rotor in the distibutor. also try http://www.allpar.com/fix/stall.html read that. there talkin about cars there but its the same sense....... if not no hurt feelings here just tryin to help

Been talking on other forums and here is suggested answer, "I'd check the sensor circuits on the cam and crank sensor both, they share ref voltage and ground. Check the asd relay circuits. Primary voltage for the coil--injectors, among other, gets voltage from the asd relay. "

Ok new problem now!! I cut the cat off and the truck will now run and rev up fine but as soon as I let off the throttle the truck will stall. but if I dont hit the gas it will idle fine.  Also at start up I have no oil pressure and then it jumps right up to 40 pounds. Then during Idle it will drop to 0 pounds. But then I give it gas and it jumps back up to 40 pounds na dthen drops to zero again at like 10 seconds later.
