I drove my truck to a photographers house because it was going to be used in a photo shoot with a model. The truck started fine at my house I drove it probably 7 miles shut it off. Went to leave for the photoshoot and it would not start!! Heartbroken. I checked cables, plugs, fuses, checked the pressure in fuel line, and I just can't figure it out. The truck will roll over starter kicks in just fine but its not getting fire even gave just a tad bit spray of breaker cleaner to see if it would even hit on it and it would not. Ive came down to either the computer or cam sensor. But I'm looking for some advice to check more things because I'm stumped. Thanks

Oh yea its a 2003 5.4 with a little over 20,000 miles on it so its not hurt at all

Do not use brake or breaker cleaner to try to start it.

Your saying the engine will crank over, but will not start?

What are the specs on the truck , Engine and what not?

Need to check to see if its firing.

aftermarket intake?
vacuum lines?
clogged injectors?
spark?
battery good?--not enough juice to crank over..
getting fuel?

Cam sensor will not prevent starting. Crank sensor, however, will. I'd check for spark first. If you have spark-crank sensor is ok. Check fuel pressure on fuel rail. Needs to be above 30psi to fire engine.
