Randomly, the truck will fail to start. When it does start, it runs a little rough, but it accelerates and idles without significant issue. There doesn't seem to be any consistent set of conditions when it fails to start - it could be morning, noon, night, wet, dry, hot or cold (weather) or hot or cold (engine).
When this occurs, I do notice that I can't hear the fuel pump "priming" when the key is turned to the start position, but before attempting to crank the engine. I thought it might be a short or bad connection to the fuel pump, but haven't been able to trace it down.
Also, without any understanding of why, the truck will frequently start and run OK again for awhile after it sits for a few hours after trying to start it. To reiterate again though, it doesn't seem to be tied to the engine temperature.
Any thoughts/troubleshooting tips?
have the same problem?
