I have a 98 Dodge Cummins 12v thats stock. It has a problem. It is a great running truck, most of the time.
It first happened a few weeks ago. I started it up after letting it sit for 4 days (never sat that long, daily driven usually) and it started right up and ran for about 30 seconds and started running very rough and losing RPMs. I brought the RPMs up for a little while till it cleared out. Then it was fine. Was fine for a week of daily driving, then it hit again after letting it sit for three days in a row. Same thing as before. Then it did it three times this weekend on three consecutive days in a row.
It never had ever done it after the first start of the day either. Only does it the first time its lit off in the morning. You can stop as many times and shut it off and restart it throughout the day and it wont do it, only the first start of the day.
I think its sucking air in somewhere on the fuel lines. This is getting worse. I have heard a few things about cracked fuel lines and an upgraded part form dodge too. Do I need this upgraded line or can I make it myself? What fittings/line size do I need? Is at the frame to engine area? or the frame to take region? or steel lines between? Could it be sucking air at any of the fuel filter junctions?
Whats the common problem I should look at first?
could this be an inj pump on the way out? Or will a bad inj pump just die?
Thanks for the input!
