i own a 1994 dodge ram 2500 2x4 with a 5.9 cummins diesel. When the truck is not used it is pluged in.If i let it sit for an hour or even a day or two it is very hard to start.When we do get it started it runs fine for the rest of the day but then at 4 oclock when it is time to go home here we go again it is very hard to start.i have checked the fuel with the right gages and i am getting fuel pressure around 21 psi. It will start if i spray alittle starting fluid in it and i mean alittle just a flick it starts right up and runs fine.Yes it does smoke alitle white no to much but that goes away in about 1 min or so. is it or could it be the fuel heater relay or could it be the fuel shut off solenoid relay.

Minor (very slight) fuel leaks in fittings can cause air to enter the fuel lines causing the fuel injection pump to loose prime. Then when you go to start it, it is sucking air into the line at the leak causing difficulty getting the prime back. Put clean cardboard under the vehickle when you park it for the night and look for fuel spots on it the following morning. You may be able to spot where the fuel is leaking and tighten up a loose fitting or replace an "o" ring. Might just solve your problem.

I have an '06 dodge 2500 with a 5.9-Liter HO Cummins Turbo Diesel Engine. When I turn the key on but before I crank the engine, I notice that the check engine light starts to blink after 10 seconds. The check engine lights turns off once the truck is started however. In the manual, it states that there may be a problem with the emissions testing and may affect my gas mileage. My dealership cannot find a solution to this problem. Any help or suggestions is welcomed.

I had the same occurence in my Ram 2500 cummins once and it never did it again. Ever since I have had the truck since day 1, it has an intermittent problem with cranking and cranking to get it to start not only in cold temps but in the hot as well, once it starts its fine but if it sits for about 5 hours its hard as heck to start. I have taken it in to Dodge 3 times and I am constantly told, "we cant find anything wrong" and that cummins is working on a fix" If anyone has had the same problem and know of a solution could you please email me at michael.francdm.af.mil Thank you

I'm scheduled to take it in to get looked at this Friday. Hopefully I'll find something out. I'll send you an update if anything worthwhile comes of it.

The twelve valve trucks have a problem with aging flexible supply and return fuel lines. They deteriorate and, even though they may seem to be sound, they often bleed air and are subject to losing prime. It is rather simple to replace them but it is not easy to do. The lines are difficult to access. If you are handy you can do it yourself if you don't mind a bunch of skinned patches on your hands caused by reaching into these hard to reach places. One line is 3/8", the other is 5/16". As long as you're doing it use marine grade line. It doesn't cost a terrible bunch but is less subject to the above mentioned loss of prime.
