I have installed & ran fuel additive, 2 tanks, changed all filter, including servicing inner trans
filter. When I get on it pulling a load in limps out at about 65mph. Please help. Leaving GA on Monday.

can you give us any codes maybe?

 

Chassis Code: C0910

Tried to look it up, but no luck. Trip to the dealer??

 

Duramax hands, a little help please!!

 

I cant even find anything on that code anywhere, not even in my service manuals for 01 dmaxes

You said it will limp when you tow? Is there any other codes?

How does your oil look, does it smell like fuel?

 

TTT

 

Sorry in distress I forgot where I posted my distress call. Well I just replaced the Fuel Pressure regulator, Boost Pressure sensor and all codes went away. Picked up my trailer, about 5K lbs. and started home got on it a couple times noooo problems. Well got on the highway and hit around 65mph and limp mode agian, pulled over turned it off a few times. Got back going and bam, same **** 6 times to go 15 miles. Got home unloaded trailer let truck sit for an hour went to get SOME well needed BEER and CEL goes off. WHAT GIVES!!!! HELP STILL TRYING TO GET TO TEXAS!!!

 

C0910 Ignition-switched power relay #2 circuit low

I don't know what it means, but there it is.

 

Oh by the way the only time this Truck limps out is pulling the trailer. It use to pull a Bobcat & trailer about 8.5K lbs w/o any problems. I can get on it all day long and nothing. I hook the 5K trailer to it and 65mph ....limp mode.

Yes..only limps when I tow. Oil doen't smell like fuel. Limps when I hit 65mph getting on it.
