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?

 

maf clean?

blown fuses?

 

do you have a retune for that big of a intake and throttlebody

 

map plugged in?

 

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.

 

i was just shooting in the dark, maybe a pcm fuse or something important was blown, id check them all.

 

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.

 

It's Running!!!!!!!!!!! I swapped the starter & ingnition relays to see if one was bad and cranked right up. Thanks guys!
