No Start..

[MrJohnWayne]

Ok I need some help with this one. My rig keeps giving me fits.

It is back to the no start crap which last time lead me to the IPR (and I swear if it is the ipr again I will light a stick of dynomight and blow this to pieces.....)

I have a short somewhere and it has something to do with the fuel system. when it goes on this no start spree the fuel pump relay will repetedly click under the dash.

It's not the icp, fuel heater, or IPR (I pray cause it is brand new!) I have checked the fuel pump harness under the truck for loose broken connections etc...

Would the IDM be causing this to happen sporadically? Could a bad alternator short out the fuel system? I don't know what is causing this. Once it finally does start it runs fine. no problems at all, but you have to "play" with it to eventually start it.

any ideas??????

Have you visually checked the wires in the engine compartment for any nicks or scorch marks? Double checked all of the connections and so forth? Sounds like you have checked everything else, and I don't know enough about the IDM to comment on that.

Have you replaced the relay? Also, a bad ground could give you fits, like that.

Hmm any codes?

It's raining down there right? Any chance water / moisture is getting into the PCM?
