got a 2001 ford f450 250k replaced lpop "mellings", hpop "t500" , injectors, icp, ipr, tested harness, no codes no/hard start everything checks out but icp pressure is way high at 1700 psi. when does start runs like **** possible bad new injector, but really concerned about high icp. replaced icp again was good for a day then high again

 

When is it 1700?

 

When it's trying to start

 

When its trying to start or at an idle?

 

when cranking goes to 1700 and above ipr% starts about 15 and goes up to about 40%

 

What does it idle at?

 

when i unplug icp truck starts and if i plug icp back in all the #s are normal runs bad but psi and % are correct

 

tried 2 different icp and same result

 

Do you have tuning?

 

yes have bullydog but does same with it unprogramed
