Just redone the O-rings on fuel rail and injectors, had problem with hpop and replaced it also had air leak the reason for all the o-ring replacement.

Now the question truck starts easy enough and idles good until I rev it up and then it misses, and almost dies when I let up on fuel.

Pulled codes and am getting several

P0046 - turbo circuit range
P0013 - intake temp circuit high input
P0267 - #3 injector circuit low
P0269 - #3 inj contribution/balance fault
P0273 - #5 inj circuit low
P0275 - #5 inj contribution/balance fault

Does this mean the injectors are bad or do I have a wiring problem?

The wiring harness was replaced, but that means nothing as I had send two pumps back before I got a good one.

Any one knows would appreciate an answer.

 

sounds like 3 and 5 are bad, but without the ability to do a balance test, no way of truly knowing....

 

How do I do a balance test? Can it be done with the AE?

 

IDK with the AE... The IDS (integrated diagnostic system) has an option in the self test section to take away the adaptive learning on the ficm so that all injectors are equal... the 6.0 ecm and ficm will (when adaptive learning is enabled) compensate for injectors that are not contributing as much as the others in its throw... it will make another injector over compensate for one that is weak and 90% of the time a driver will never know until the weak injector fails, then typically the injector that has been over compensating is soon to follow.

 

Found a way on the AE. Shows an occasional spike on #3. But the rest run about the same.

Am now having another problem. The truck starts good in any weather (any for south east Texas) the coldest it has been here is 44% so not really cold.

The truck does not idle very well, lopes and misses, does a little better when warmed up, but still not right. Now am having problem with high pressure. The truck starts before low pressure is shown. And the inj control pressure actual runs about the same as desired (649.66 actual to 648.1 desired for up to an hour) Inj regulator is 22.66% Reg volts 0.92.

ficm logic power 13.50 shown in red, ficm main power 48.50 also red, ficm vehicle power 14.00 red, inj sync is 1 red. inj timing -3.28.

It has started again after about an hour of idle and kill it, the highes hpop the ae shows is 270 sometime up to 400.

If I had another hpop leak it would not stay the same at an idle for that long would it?

Bought this truck because no one could get it to start and run.
