6.7L Cummins Forum

I just got the new computer flash and my truck keeps setting trouble codes

000f and
p-1011

one is fuel rail pressure low and the other is fuel pressure too high relief valve triped the deal is letting it set overnight because he could not get codes to reset. It seems the codes set when im in 4x4 and floor it all the way up to 70mph. will not set codes as easy in 4x2 but will set them. I was wondering if it would have somthing to do with injector pump?

Thanks

Your profile does not tell us what you are driving. Take it back...depending on the truck year and flash, it can be really tricky to do the flash correctly.

I did take it back they could not duplicate code but as soon as i drove it the code comes up when i floor it from like 0-70mph. I was woundering if the fuel lift pump could be going bad. I have 2500 6.7l swa

oh and i am getting a code p0087 p000f and p1011 all at the same time

I'll look the codes up and get them posted but I suggest you take the service advisor or manager for a ride and reproduce it for them.

I took it back to dealer they talked to cummings which put the tech through a 7 steps of tests and have him replacing the fuel rail pressure relief valve and putting a factory fuel filter on it. There telling me the parts and time to put parts on the truck are covered under warrenty but not time to diagnose the problem which is already over $300 and if not fixed after this will be more money. The parts and labor are over $700.00 so its over $1000.00 so far and truck only has 73,000 miles on it.

What kind of fuel filter did you have if they replaced the old one with stock?

I had used a fram fuel filter but come to find out the pressure relief valve that sends fuel back to tank was poping and not letting all the fuel to go to injectors so they replaced fuel filter and relief valve and seems better now. The odd thing that they charged me like $300 to diagnose the problem and said cummings will not pay for that just parts and labor.
