will rebuilding the IPR fix sticking issue?

[lariat 7.3]

Ipr is sticking pretty bad. Will rebuilding it fix the sticking issue or should I just buy a new one

Are you noticing it sticking while watching icp VS DC% on a scan tool? Or is the % going out of range? anything above 60-70% will throw the p1211. and honestly if the pump cant do desired ICP below 50% DC then a pump upgrade is due.

Id try the free option before the almost $200 option

Brand new t500 kinda have two threads goingon. I know for sure its sticking. Sudden acceleration when not moving my foot on the pedal, cammed out dragster when started and getting a low icp code

Whats the free option ghouston

If you tear it down to where the little needle comes out be careful putting it back together the little needle can and will break if put in wrong that is a $200 mistake and no fun. Otherwise its not a bad job.

sent from the app I paid for now its free and they have dumbed it down to a free version and want me to buy another paid version even though I have paid for it. Stupid Tapatalk!

You can just pull it apart and clean it.

If you mess up an o-ring, you will need the kit.

How does the pigtail look?

Prefect, same with icp. Keep getting a injection pressure lower than desired. When you first start it there's no cackle or anything.extremely quite. And I keep getting a camshaft bank A or something code

Normally, that is more of an electrical code with the ICP sensor--if you disconnect the sensor it trips. if the sensor starts to freak out, it cannot manage the IPR. When it trips, the system goes right to 725psi default. Either the sensor is going bad, or you may have an wiring/electrical issue in its power supply.

The 3 pin sensor power supply plug should show .16-.28 V at KOEO.

Is this why my truck is loping when its cold out for about three or four seconds? Then smooths out.

Threw in an ICP sensor I had laying around and it seems like she's back to her old self!

After it gets up to temperature, while engine is running, unplug the icp sensor.. if there is no change then the sensor is shot.. if it changes then the sensor is still working... oil in the sensor is bad but I have seen them run fine like that then have a fit for a sec then run normal again...
