is this code always gonna be the hpfp? lets hear some experiences with this and how the dealers handled the warranty repair. thanks.

well what do you want to know? the majority of P0088s are caused by a sticking pcv in the high pressure pump. it could also be caused by a bad frp or a problem with the harness. only diagnosis will tell you

My 2008 F450 has been to the dealer now 5 times in 4 weeks, I did as much research as possible and have explained that they should replace the HPFP but no luck yet, they say "A Ford engineer must approve the change" not sure if this is B.S. but I'm really getting tired of getting jerked around. Any advice would be appreciated for those that have been through this, I've gotten stranded with a load now a few times on the way to a job site, starting to really hurt me (my business)...

i've never had one hint of trouble getting prior approval for a high pressure pump. unfortunately your dealership probably isn't familar with the situation

I had the PO87 code show up at 117K miles....08 f250, had ext warranty, Ford sent a rep out to give the truck a look...repair was approved. I was told it a poor design for a HPFP...and was lucky to 117K miles with it.

Thanks for the reply guys, I'll let you know where it goes from here, maybe it'll help the next guy...

[Mr.Big]

Still getting the same run around, after 7 days at the dealer this time, they are still claiming that they are waiting for approval from a Ford engineer to go ahead with the HPFP change... really, REALLY, getting irritated at this point... wow

[sinner6.0L]

that's entirely possible and even more likely with an ESP claim. basically what happens is when you submit a prior approval form to ford for a pump replacement you need to tell them exactly what you did to diagnose the concern. then ford determines if you've provided sufficient evidence for your claim. if they want they'll send out an field service engineer to either verify your diag OR possibly even take a fuel sample.

if the fse takes a fuel sample it'll be even longer

Thanks for the feed back Sinner
