I bought my 3500 4X4 Ram new in 1999, now has126,000mi. It's been flawless - except yesterday. I stopped in a prkg lot for 10min, came out and it wouldn't fire. It's ALWAYS kicked off in less that 2revs! I bled the fuel filter container, elec fuel filter is working, fuel at top of canister. I just changed the fuel filter3,000mi ago. No blown fuses. Tried spraying WD40 through intake while cranking...nothing. I filled with fuel the day before. My daughter had the ignition ON (not acc) for about 5min before I got back to the truck to start it - that's the only thing out of the ordinary. It cranks well, all gauges working.
ANY IDEAS???

 

Can u hear the fuel pump running,to key to start for a second then listen under hood for fuel pump should run for about 30 sec

 

YUP, the fuel pump runs and clicks off normally.

 

It's just the weirdest thing!!! Like there is a "kill switch" turned off.
I was hoping someone would tell me there's a reset button somewhere
I'll probably go out and put another fuel filter in today and see if that works, but I was told the WD40 would allow it to fire if it's a fuel problem (kinda like ether for a gasoline-carbed engine).
Then have it towed to my local diesel house if it doesn't work.

 

Check 4 codes ign on/off on/off on count the flashes on odometer should flash then pause i.e. 5 flashes pause 8 flashes

 

Disregard my previous post(brain fart)thinking of how the codes flash on my dakota, do the same process with the ignition, the odometer should flash codes in a po#### i.e po1693(which is a ghost code, doesn't relate to any problem followed by other po#### codes) someone posted the codes on this forum under 2gen ram I think, if not a haynes manual lists them

 

PO### codes sorry again

 

Truoble code list posted on this forum by drew

 

Thanks...I'll check that out!
