    Have you ensured that the intake is torqued down to the proper spec and there are no large vacuum leaks? There was another member here who just ran into a similar problem and went through days and days of headaches trying to figure out what his issue was, and when he tore it down again he found a 8mm socket in there

    I just dont think im geting fuel because i can undo my number 1 plug wire and turn the truck over for about 30 secs and there wont be a drop of gas or cant even smell gas on the plug

    have you looked inside the intake to see if that spider is leaking? The intake will be washed down with fuel if it is. What engine is this....5.7? It sounds like you've already done my first thought. I had a 98 4.3L that was doing the same thing.....ended up being the fuel pump. It was only off 2-3lb's but it was enough to keep it from starting. Did you go back over your install and make sure everything is hooked up correctly and there are no issues with the install? 9 out of 10 times if something was running prior to working on it then it's a mistake made when putting it back together.
