What is IM mode and why am I getting these
LT FTRM1 stuck at 24.9 volts they do not go up and down like the other banks
LT FTRM2 stuck at 24.9 volts
Any ideas Thanks

 

huh?
whats the code..p0171 or what?

 

yep system lean banks 1 and 2 you got it

 

ok..p0171 and 72...the fuel trim numbers are way high...its either starving for fuel or has a big vacuum leak

 

I think I found the major Problem Checked fuel pressure and its only 21 lbs with engine running
it was almost 0 at key on engine off KOEO and then started only went to 21 lbs Fuel filter is new
so its either the fuel pickup is clogged at pump or pump is very weak and on its way out.
Anyone think this could also be a badly worn ground Im goning check that 1st I haer its behind the drivers
front tire on the frame.
Thanks all

 

doubt it...sounds like pump time

 

I changed my pump a while back. If you have a garage and a helper then it is wayyyyyy faster and easier to pull the bed rather than drop the tank.
Im working on the same problem. p0171 and p0174, cleaned the maf sensor, checked fuel pressure 52psi. It should be 55 to 62psi. No fuel line leaks cuz the guage held the fuel pressure for about 15 mins and did not drop. Checked the maf readings and it appears to be working (grams per second and my code reader does pounds per minute so I had to do a little conversion) but it appears to be within parameters at about 7 to 8 grams per second at idle.
Im just gonna change the fuel filter today and keep my fingers crossed that it is not the regulator cuz what a pain that is too check. Fuel shut off valve on the return line, I couldnt find one yesterday online with the little fancy disconnects and such so I am changing the filter and hope. If not then is there a okie way to shut off the return line to see if the pressure increases?
