Well i got back to try the old chip no luck with that, checked the icp when i took off the connecter there was a very little bit of oil on the prongs, but with that off should the truck try to start? still no smoke at the tailpipe.I did try the fuel selecter switch and that is working.

x703 Unscrewq your fuel filter cap to see if there is any fuel in it. If its not over half way, youll need a new pump. That is unless its been very cold where you are. Then its possible for fuel line gelled.

I just re read what I posted 2 posts up. Its backwards. If its full you need a pump. If its empty you have other problems. Sorry, my fingers got ahead of my brain.

Thanks guys you were right on the fuel being bad, it broke off at the o ring and was stuck in the block.Got it out without to much trouble put it all back together still wont start,getting a little smoke out the t pipe, 36 degrees out, its been pluged in for 4 hrs it doesnt even sound close to starting, bats are on charger when trying, fuel pump filled the bowl went through all other suggestions you guys told me about it still has this new problem when i go to lock it with the remote the running lights stay on.You have to take the neg cables off for them to go out. Any ideas?

still got a short open somewhere. Do the lights stay on when you hit the power lock WITHOUT using the remote?? If not, the remote relay sytem is sticking. If they stay on if you htt he power lock button in the truck, then you need to talk to someone that knows more than me...LOL

On the starting, it may take 4 to 5 cycles of cranking to get some fuel to it. Also check to make sure that your number 22 fuse under the hood is not popped. Thats about all that I can think of off the top of my head, unless your low on oil, that will do it too.........

Check the pressure while cranking. You should see something.. if not try switching to the other tank if you have one.

No electric shut off on the FP but you may have a restriction from the tank(s) to the pump. Blow air through the return line, you should hear bubbling in the tank.

WAG: Are you low on fuel? The fuel pickup tube in the tank have been know to crack. Ususally it surfaces as a bad running engine first (aeration) but if you parked on an incline the crack may be totally exposed....no fuel.

Does the wait to start light come on when you turn on the key? also check the High pressure oil pump reservior


Also you won't get any pressure at the schrader valve until the fuel bowl is full. How long have you cranked the engine over?

It could be the IPR. Make sure it is plugged in for one. Also unplug the ICP (see pic above) sensor and see if it will start then. Also do you have any friends with a scan tool that can read live data? it would be really helpful at this point.
