Troubleshooting 99 Chevy C1500 pickup 5.7

Hey all. I am hoping someone can help me without me having to tow my truck to town. My truck for the past few months has been really hard to start.
The fuel pump is working, I have spark and compression (cause one I get it running it stays running and works fine) I have changed the crank sensor, cap and rotor, and put in a new fuel pump relay switch. I am not sure where else to look now. Can anyone give me any direction as to what to look for next. Like I said I am trying not to have to tow it in to town as I live quite a ways from any decent mechanic. Thanks.

I have the same problem with my 93 and I've narrowed it down to the ignition module in the distributor....although I haven't changed it yet. It is stuck in the driveway.
You say you have spark because once it starts it runs....but you need to stick a test plug or timing light on it and watch it when you crank and it won't run. I'll bet you don't have spark (and ignition pulses) regularly. That is what mine is doing. If it can get a few sparks in a row, the injectors will open and it will run and stay running. I would have bet a paycheck I had spark until I put that inductive light on it....now I'm singin' a different tune.

Put a pressure guage on your fuel line by the intake manifold. I had the same problem. Mine would start after a while but kept getting worse. My fuel pump went. Make sure that you are getting between 60 and 66 psi. I replaced alot of sensors before I broke down and replaced the pump.
