I have a 1998 Dodge 3500 , 24 valve cummins. Experiencing a frustrating problem. When parked up hill, and left a few hours it will not start, get it turned downhill, roll it, and it will start. Replaced the overflow valve, and it started fine for a few days, then back to the same. Took it to the injection services that rebuilt the injection pump, just over a year ago, they analyzed it and could not find any codes. They again replaced the overflow valve, and it was OK for a couple of days, and now it won't start again on an incline. The other thting that may be coincidental is when I engage the exhaust brake, now there is a a 2 to 3 second delay, before it will accelarate. Hope someone else has experienced something similar. Thanking you in advance for any suggestions.

 

Go over to the Cummins forum and talk to Drew or any of them, they'll prob know.

 

Yeah, sorry. I don't really know anything about a diesel. Except I wish I had one. Sounds like a fuel problem thought. Fuel pump maybe. Have a good mechanic chech it out.

Where you located?
