HELP!! 2005 5.9 cummins won't pull hill with empty trailer

[coolinit]

Idles ok but will not run right when fuel demand is needed or when pulling a trailer, Had new injectors installed and new turbo but the truck acts like a gas engine with a faulty plug. Doesn't smoke and normal fuel mileage is 18 mpg and its getting 13 mpg. No faulty codes come up. Anyone know what the problem could be? Thanks

Your obviously not getting any fuel. Im by no means an expert but Im thinking that your lift pump is bad or maybe a clogged fuel filter. Does it miss at all? Did it happen all of a sudden or gradually?

Your lift pump or injector is bad. If its injector you may have white smoke when you start truck.

Air leak on intercooler connections some say to use shaving cream it will show where the leak is

sounds like a cp3 problem

Are you 100% sure the transmission is not stuck in some gear like 3rd or 4th? mine did that once and I found that I had blown the transmission fuse while installing a fuse box mounted accessory.

post more info on how your engine is running. RPMS, temps, different noises, increase in crankcase oil level, etc.



It will help the others in the TDR help you. Good luck.

If your truck was running o. k. before the injector and turbo upgrades I would suspect them first. Bad injector or turbo not spooling up.

Did you check for codes?

Ditto that theory!!!!!!



Only seen it once, hard to detect, and will fall on it's face big time due to no boost.
