Updated---Cutting out on grades?
« on: July 02, 2008, 12:25:52 am »
A friend of mine has a 2001 5.9, 5speed manual, 4x4. He just had a new intake, exhaust, injectors, an edge w/ attitude, and a fass system installed on his truck about a month ago.
He is on his way to Utah with his family and the 5th wheel. He is having issues when going up grades. He says it will just lose power all together. If he lifts his foot off the pedal and then floor it again, all his power will come back. He does not lose anything when driving straight and level!!! Any ideas why?

yeah its his overdrive, the things a PITA. Going up grades power will just disappear unless you release and give it gas to downshift. Tell him to take od off when going up grades and he should be fine.


My lug nuts take more torque than your ricer makes.

man just having OD on with a fifthwheel is gonna be a strain on the motor on a flat road. Rember even though it takes less effort to maintain a hwy speed you still have a lot of extra weight as well as wind resistance.


Just Imagine how many rep points I'd have if I didn't piss off so many people.

Its a 5 speed manual, not an auto, so no overdrive.

A shop did. He did the intake, exhaust, injectors, and the edge first. He threw a code and it had something to do with his fuel pump...or something like that. He took it back to the same shop and they couldn't figure it out, so they installed the FASS pump for him. It goes like a bat out of hell, but while hauling his 5th wheel up hills, it just loses everything until he lets off the gas. And that is the only time it does it!!!!

does it only do it in a certain gear or a certain rpm?
I'm not familiar with standard, if it were an autmatic idhave guessed the torque converter was acting up.

well you can't climb a steep grade in 5th gear, even with no load that would be a strain.

New info:
He got a check engine light while climbing the grade.
When he got back home, he took it in and had it read by the guy that did all his add ons. The code was Injection Pump timing Failure. They are not sure, but they say it could need a new injection pump. They said they will change out his injection pump if he wants, but they aren't positive it will fix the problem.

They also mentioned that he may also want to start using an additive to his fuel because Calif. diesel doesn't have enough lubrication.

Eeeewwwww, injection pump timing failure is the big one.

Time for a new injection pump.......to the tune of $1000 or more.

Yeah, thats what he was telling me!!! He actually got the code before he left for his vacation to Utah. Thats when they put in the FASS pump.
He's on the fence right now about replacing it. They aren't positive it will fix his problem!!! On the bright side, they gave him a new injection pump before he left for his vacation and didn't charge him for it!!!! They simply said....If you need it, then pay us when u get back....If u don't need it, bring it back!!!!! Don't find many companys like that in california!!!!!

He's looking for some input from us:)

If he's getting the timing code, the pump will solve it.

I'd almost guarantee that's his issue.
