I don't know much about those trucks with all the extra valves, but I would bet on the problem being the rubber fuel hoses drawing air. You stop, the engine cools a bit, fuel contracts, air enters. Something like that.
Good luck.

<br>i dont think your getting air in the lines i believe its an electrical problem. give me some time and i will try to look it up in one of my manuals

 

Does anyone have any ideas ,tried eveything I can think of on the hard to start,wont start 99 Cummins<br>open to any suggestions,dont want to go to dealer.<br><br> Thanks,<br> modguy

 

I'll take a guess here...<br><br>Have you tried to reset your APPS?<br>I have no idea if this is going to work, just a guess.<br><br>https://www.dieseltruckresource.com/...p;onlynewfaq=1<br><br>May also be your idle speed is too low (in gear), but I will admit that I dont know if your idle speed would affect its ability to start ???<br><br>Good luck.<br>Rich

 

Just returned from &quot;***********&quot; after scratching their heads since about 9:45 this am,it is now <br>5:45 pm ,they decided it is an injector pump computer something or other breaking down when it get's<br>hot. I don't whether or not to buy this assesment or not ,they are saying it's an $1800.00 fix job.Can <br>anyone confirm this or not ????? The reason for the 1800.00 cost is my 100,000 went out about 2 weeks<br>ago,(103,000)now.<br> Thank's<br> modguy<br><br> Thanks to all for the responses so far!!!!
