This may sound really strange, but about 2 - 3 weeks ago I worked on an Impala that was doing the same exact thing. It had spark, it had fuel, everything but it would just crank all day. Turns out, the cats were absolutely clogged beyond belief. I removed the exhaust from the midpipes back and it fired up no problems. Put them back on and it did nothing but crank. Replaced midpipe and problem solved.

I know it sounds strange, and I'm not saying that this is definately your problem. But it is something to think about.

Of course, I would look at other easier things first. Did you check to make sure every plug is getting a spark? Wouldn't do much if only one or two were sparking. Are the plug wires connected to the right plugs? I've seen that before too. Timing okay? Etc..

From what I've heard,MOST GM carssuffer a problem called Isuckitus.The definition of Isuckitus is anymajor or minor hasslethat occursdue to their****ty built drivetrain's or engine's. From either too little distance from the engine and dashboard,or having pablo and hisfriends from Taco Bell take weekends off to handbuild some cars down at the Chevy/Dodge factory some problems occur in the production process. Usually burritosstuck in the manifold, stock blocks stuck directly to mufflers, orPedro's idea of more hpcoming from the engine if he put's it in thetrunk(not connecting it to anything)liketheGORMEN"S do with their PORCHES. I hope this could help you decide to sell your truck to a junk yard for $10 and help build yoursavings for a nice powerful and strong F-150 or Ranger!
