$2000 HPOP

Hello, I have a 2002 F350 7.3 ambulance. Was driving great the other day, then suddenly check engine light came on and loss of power. This is a daily work truck and it is my busy season. I made it to my next two jobs, then had vitually 0 power. It would crank, no bad noises, but RPMs would not crawl up at all. Had it towed to the dealership and they are saying I need a new High Pressure Oil Pump for a total of $2000. Seems steep for the job, but it's costing me money not having it on the road. Are there any other questions I should be asking such as what else they are replacing, etc?
Thanks!

I'd ask how they diagnosed the HPOP. That's a little abrupt given it is one of the most reliable components in the system. The IPR valve is more often the culprit when you can't build pressure. It could also be a downstream leak (like a ruptured injector o-ring) or an upstream feed issue (like a bad low pressure pump or cracked pick up tube).

To condemn the HPOP, they would need to have done a block off pressure test on both sides of the pump with a known good IPR- ask for those values.

2000 dollars hpop cosy round 500 so 1500 in labor that's high. To be honest anyone can change the hpop it's not the biggest job out there. But I do agree with @RT I would ask for the diagnostic sheet with numbers of everything. On 7.3 the hpop is usually not the problem unless you have long overdue oil changes that what kill a fleet truck that I took maintenance on they got a fleet of 10 and all get 15w40 (4 are gas burners rest diesel) and all get a 7k to 8k oil change

Could even be a failed Icp. Unplug it and try and start
I agree with other guys. I doubt it just failed.

This is exactly why I bought a scanguage II. I monitor my vitals while driving including the ICP pressures, IPR duty cycle and many other items. If some thing is wrong with the IPOP it will show so If I get caught on the road and have to be towed at least I will have a pretty good idea of the problem before they give an estimate. Does not take much room on the dash.

I wouldn't doubt a quote of $2000 for replacing an HPOP. Autonation WBL sells a reman for $644, with a list of $837, and what dealer gives you a discount on parts they install? I just R&R'd mine to fix a blown out "non-serviceable" plug o-ring (replaced all the o-rings on the HPOP except the rear cover, just to be sure). I think I was at it for at least 8 hours, but again, I'm getting old and decrepit , so take that with a grain of salt. But at the prevailing dealer labor rates, I wouldn't doubt the $2000 quote.

But like everyone else said, it's VERY LIKELY NOT the HPOP, but some other component causing your problem.

Happy to hear that some other forum members are old and decrepit like me.
