Home Page is where I took it.
I can only imagine the guy knows what he is doing. He came well-recommended in my area.
But I really don't want to pay him $1500 to do it, especially if I can do it myself, my real concern is that I replace the HPOP and it doesn't fix the problem.

I just asked him more about it.
He did not do a leak down.
he told me "we see three or four of these a month... it's always the pump"

and the $750 is a reman'd pump.

if I bought my own parts he still wants $500 to install them.

 

I have over 1.5 million miles driving and owning the 7.3 powerstroke...

In all that time I have replaced 0 hpop's that have failed. They are not problematic at all.

If he wants $500 to R&R a HPOP then tell him to kiss your ****. Thats 6 hours or more of shop time for a job that takes less then 3... And thats if your slow.

More then likely everytime he has a no start powerstroke come in he throws a new HPOP and IPR at it and it runs... Wow... Now you dont know if it was just a bad IPR, or a weak pump or a weak pump with a bad injector...

I hate parts changers...

 

so what would you recommend?

 

Tell him if he wants to be a big bad diesel tech to get the proper tools and do a leak down test.

Or pull the damn thing out of the shop, get yourself Autoenginuity

Riffraff Diesel: AutoEnginuity Total Ford Enhanced Bundle

And start testing...

If its the HPOP you can also get one for RiffRaff and still be money ahead of dickweed diselmechic...

UGH... I hate parts changers.

LOL

but replacing the HPOP will solve my no start issue?

 

HPOP"s get weak but dont go bad my mech said, he also said 99% of the time the hpop is not a a culpirt in a no start. I had a identical problem as you ounce and it ended up being the fuel bowl heater shrted out and blew the fuse but you said they werent blown.

 

so if I'm reading correctly... the injectors require 500psi from the HPOP to enable.
The pressure is measured at the ICP sensor. If that sensor is unplugged, then the truck "assumes" the pressure is 725psi, which should enable the injectors.

 

If I said yes, that would make me a parts changer...

I would disconnect the HPO lines, test the pump with the lines dead headed.

If you still get low or no pressure, then your problem is your HPOP.

If you get pressure then reconnect one line and plug the other and test again. If you get pressure then reverse.

That way you could isolate what head has an injector problem.

Mechanics dont change parts, or at least they used to not.

 

So I just went up and talked to the guy.
I asked him to show me how tested the oil pump.
so he plugs the high pressure lines with adapters, and hooks his NGS up, cranks the engine, and shows me 197psi from the ICP.
fair enough.

as far as the price of the parts. He explained to me that he gets all his parts from the Ford dealer up the road, that way, if there is an issue with them, he can just pick up another one.

I can give him my own parts, but he won't guarantee them.
