Guess I should do a signature, huh? All of the fittings for fuel are tight and dry from the filter to the injectors.

Could be a cracked fuel filter housing. Seen it happen quite a few times now.

NEVER CRACK A COMMON RAIL HP FUEL LINE..Whitmore knows this just didnt say it lol

I would not crack a fuel line on a dmax

when cranking over are you getting any smoke or fuel smell?
is the security light flashing?
do you have a scanner of somesort to check voltage at cranking?

I only have time to work on it at night outside, hard to see smoke. No smell. No light flashing. Have a scanner, but can't check voltage. If you are asking about batteries, I have two new batteries I just got. I will try to get the filter housings changed between pickups here in a day or so. Surely both can't be cracked. And what is wrong with cracking the lines? Or do you think a common rail system could do something with the little bit of pressure?:hurt:

the cr system will bleed it self anyway, ive replaced injectors many times and itl fire up with out bleeding the injector lines, just takes a while.

where you located? maybe some one with a good scanner can see whats goingon. try unplugging the FCA and turning the engine over, this will command 26kpsi. are all the wires connected and snug? check the number 5 and 7 injector harness make sure they are making solid connections, back two on the passenger side)

FCA?? Where/what is that? And i am in tulsa ok, don't know anyone here. I really wish I knew how to check the computer. The guy told me the other day the dealer said both needed changed.:ouch:

2500HeavyDuty 10-30-2009 02:53 PM

FCA / FPR the little electrical connection on the cp3.

Check the fuses in the panel under the hood. I had one blow and it would do the same thing just turn over and not fire. I cant remember if it was an ignition wire or one of those that say Injector fuse. Its something else on the diesel but cant remeber what. Test light or pull one at a time and check.

is it one of the gray square ones (breaker) or a fuse? I thought about that, but I don't know how to check the gray ones.

It was a 10 or 15amp fuse.
