Killed my truck?!
 

Thanks in advance for any advice.
2001 f150 5.4 triton.200k.
Installed a dorman intake this weekend, put everything back together , no extra parts, every hose and wire connected.. No start. Cranks and cranks. Tried four or five times, cranked for maybe ten seconds a shot. Tried a shot of either in the throttle figuring it would pop over a little on the either if it wasn't getting fuel, but no joy.
Help! This is my only ride I need it to get to work.....

Fuel shutoff switch not popped...There is pressure at the fuel rail, I don't have a gauge but I depressed the schrader with the ignition on and there was flow...

Ok, so 35lbs at the rail, I'm getting 12v and signal at the coils, try's to start, first time I try with a fully charged batt, but I don't think it's kicking on all cylenders, kind of like it's flooded..
Anyone have any ideas?

Could a cps fail,and,give me spark at the wrong time?

is there any chance at all that the main wire harness has been tampered with or rattled loose at all? mine had an issue just like that turn over and no fire. main wire harness had a female pin that somehow got rattled back and wasnt connecting after that it started no problem. its located behind the battery on the firewall if u care to check it out. not sending u on a goose chase but thats where mine led me

Ii also would assume since you took the harness plugs apart and put them back together, that something did not get plugged in all the way.......

also, put the key in the ignition and turn "on", but don't crank..... THEFT light should come on for a few seconds, recognize your PATS key, then the THEFT should go out. Right ?

Thanks for the replys. I pulled the fuel pump fuze, it started like that, ran for maybe 20 seconds , died, I replaced the fuse and it fired right up...I guess I flooded it with a couple squirts of carb cleaner on the throttle butterfly..
