    I just changed out the power steering pump and did the water pump with everything off. I also did the LIM as I had a small leak out of the sides. I put everything back together and now it will crank and start for a second but then die right away. I had the ignition control module checked which was fine, I have 55 psi at the fuel rail. I then unplugged the MAF and it started fine but then revved super high seemingly out of control. I figured it might be a bad MAF so I swapped it out and the same thing occurred. It would crank start and then die. I unplugged the new MAF and then it revved super high.

    I'm at a loss. Is it my throttle body or TPS, perhaps a bad PCM. Please let me know I'm completely stuck.

    check to see if the maf fuse blew, its marked ign. you can also make sure the maf's pig tail wires are in good shape.

    also make sure all your vac lines are back on and not broken. they get crappy and dont like to be messed with later in life.
