Default Help truck not cranking!

I just did the 90mm F.A.S.T. Intake swap. Everything is connected, checked like 5 times including the grounds.

Let the fuel pressure build up about 7-8 times before cranking it. Cranked it, it idled below 500rpms surging and died. Hasn't cranked since. At first I thought it was the VATS. Did the system relearn = nothing. The security light didn't even come on when doing it. Thought it was the battery, tried jumping it = nothing. I pulled most of the plugs out and most of them had a bunch of carbon on them, replacing them right now.

Any idea of what this could be?

I got my tune adjusted through the mail from futral. The MAP sensor is plugged in, but the fast intake doesn't have any clips, but it's in there. What fuses should I check and where?

I took my alternator to the auto store. The charged my battery as well. It was low, but not too low. Fixing to go install the alt. & battery and see if the charge made a difference.

look at the fuses in the fuse block under the hood to see if it's blown. it's one of those big ones. this sounds the problem.
