iam working on a 99 2500 24v. It has about 15-16 psi of fuel pressure with the key on. When cranking engine it drops to about 6 or so. I could only get it started 2 times today, but when it did start it ran fine. I did put in a new fuel filter, bleed all the lines. Now here what i cant figure out, when its running and i drop it in gear it will die. and will not start up again?????. Like i said it ran great for about 15 min, and thats when i droped it in gear. I didnt have the pressure gauge on it then to see what the pressure was when it died. I died just like that. no spitting or sputtering, just like i turned the key off. Alos, i cracked the # 1 line and cranked it , didnt seem to get a whole lot of fuel out of it either, I crackred the # 3 line and got more fuel from that line .......Any ideas at all?? Thanks And does anyone one the web address for cummings. Like to get a price on a lift pump

 

Sounds like you might be chasing an electrical gremlin. ???<br>Cummins website: www.cummins.com<br><br>BTW no &quot;G&quot; in Cummins <br>My local Cummins store shows the lift pump retails for ~$160.<br>I've heard reports of Dodge parts counters asking almost double that price for the exact same part. &gt;

 

Yea thats what ima thinking, so off to the dealer it goes. Ill post what they find out.

 

Well, dealer says there were many codesthey got out of it, all pointing to the injector pump. guy i bought the truck form said he was driving back form a trip when it started running bad. Drove it a while then pulled into a gas station , there they changed the fuel filter, he said it was plugged. The truck has never run the same sence. I was doing some reading on here and came across a post about a plugged fliter causing the inj pump to go bad. Kinda all comes together now. He never had a gauge on it . IT WILL NOW !!. iam thinking about a digital fuel gauge. Anyone have one there using? Good or bad. ????

 

Turned out to be the inj pump

 

COOOOOL, glad they found the trouble. ;D<br>I assume it was replaced under warranty?

 

No, This truck has a rebuilt title, Even thou its a 99 with 67.000 miles the warrenty is VIOD.. .But i did the job myself , so it wasnt too bad about $1000 all said and done . Thanks Again.
