Help....Intermittent No Start

[caschu0]

Over the past week I have had 3 instances where my truck would not start. The truck is a 2003 7.3L with 69K miles. In all 3 cases the wait to start light would not go out (outside temperature has been warm), the check engine light (looks like an engine block) was on, and the fuel pump would not turn on. The truck would just crank over and not start. After I let the truck sit and came back to it an hour or so later the truck would start and run fine (fuel pump would come on when ignition was on and wait to start light would go out after a few seconds like normal). Whatever is going on is causing the wait to start light to not go out and the fuel pump to not kick on. The truck has not died or ran rough after it starts (at least not yet)....its just an intermittent no start. Does anybody have any ideas on what could be causing this? I thought it might be the ICP, but I was told by a Ford mechanic that the ICP has nothing to do with the fuel pump issue. Thanks for your help.

Anyone ever heard of this problem?

Very likely your starter.

check your gpr and fuel pump fuses. and the gpr itself.

Thanks....I have a spare GPR so I'll swap that and check my fuses.

Mfdboy.....did you have a problem like this that was related to your starter? I wouldn't think it would be tied to the fuel pump or wait to start light, but I'm wrong quite often. Can you tell me your experience with this? Thanks.

I changed out my GPR to one of the big Stancor relays......so far the problem hasn't repeated itself with the new GPR. Thanks for all the help.

Correction.....it is not fixed and wouldn't start after work today. Same problem....I guess it wasn't the GPR. Any other suggestions?

sounds like a connectin issue....or bad pcm. but i would trace the wiring down. where to start i dunno.
