02 powerstroke starting problems

[pugsley88]

I have an 02 powerstroke, I have changed the glow plugs,, glow plug relay, valve cover gaskets, batteries, starter and the cam position sensor. Still won't fire unless I plug it in. a friend told me it might be the intake air heater element, he said it works with the glow plug relay, if one is out they act like both are out. any suggestions?

This time of year, you don't need glowplugs at ALL to start and the AIH ("air heater") has nothing to do with starting any time of year...

No, you've got other issues... What you really need to do now is to monitor the sensors (ICP & IPR) to see what going on with HiPres oil that drives the injectors, as well as a history of any codes set. Sounds like you're doing the right stuff (CPS, UVCH, Starter (you've got good cranking speed right?, the batteries are all they should be?))

Current with things like Fuel Filter & Oil changes?

Find somebody with the right equipment to diagnose stuff, unfortunately the "Free Scans" offered by the parts houses aren't any help as our engines are Not, strictly, OBD-II. You need professional equipment or an AutoEnginuity...

Yes oil changes frequently, fuel filter every other oil change, batteries are interstate 850 cold cranking each, only a year and a half old. Starter speed is normal, although I am on my 5th starter in 2 years (AutoZone).


Other issues engine light comes on when I pull a load, usually at higher rpms. With some turbo chatter, also truck has an exhaust leak ( still looking for that leak)

Truck has 145,000 miles on it.

Are you "chipped"?

If so, a CEL with full throttle, under load / hi rpm, is probably normal.

If not, maybe a sign the HiPres oil is Not what it should be (either because the pump isn't capable of producing it, or it's leaking away) and could be the whole problem you now see.

Either way, getting it on the right scanner will let you know...

Yes bully dog programmer power pup 3 stage, I keep it at the 50HP setting.

Thank you,
I will take it to ford and have them run their scanner

Ya know,,,, for the future maybe, you could actually Own an AutoEnginuity for around $350. I don't know what it costs you to take it to the dealer for a diagnosis, but might be something to consider...

[pugsley88]

I think it is about 200 or so to do a full diagnostic, not just the computer check, they check for oil leaks, front end ect, I am just tired of plugging the truck in year round to start it , well for the last year i should say.

Thank you
