newb question...ipr replacement

[the549]

hey all, i have a whole slew of questions that would be REALLY GREAT if someone could help me out with, since i need this truck ASAP! check here:
95 7.3t f250 quit running...cranks, and i'm stuck!

ANYways i'm at the point where i think i should check the ipr...i'd replace it soon as yesterday if i could diagnose that as being the problem, but random shots in the dark are pushing component costs over 1k$ quick, money i don't have.

WHERE the heck is it? Do i have to remove the fuel filter housing to get at it?

IPR will run you 180 for a new one give or take.Do you have a scan tool or AE available

The IPR is right under the fuel filter in the back of the HPOP.It will be on your right side and have two wires coming from it.There is a brass barrel on the back of it and stamped brass nut that holds the barrel on.You need a Super deep socket to get the IPR out I am not sure on the size.

Where do you live?

Well, i thought i had a scan tool, but it's an $80 one from autozone, so maybe it doesn't work...i can buy components, i just cant buy EVERY component...

I did find the thing, i'll try to rebuild it with rings etc. No idea if that's the problem. Not getting fuel. Runs on starter fluid (only run it for a second like that). Originally died on a long drive after switching to the rear tank with water in fuel light. Check that link above for more info.

edit to add: i can measure fuel pressure at the shrader valve right? around 40 pounds when cranking or something?

I'm in northern CA.

Those AZ scan tools will not work on a PSD

I am not sure on the FP on an OBS truck

IF there is no fuel then it is not an IPR issue.

bad injector harness?

I'm VERY new to this but I thought the ipr could stick open and not let the hpop pressurize the injectors?

I replaced both valve cover gaskets and under valve cover harnesses. More info in the link above. Gonna try gasoline rag and wd40 today. Appreciate the responses.

sorry i havent read all of hte link yet, did you try pulling the fuel bowl and cleanign it out? maybe its clogged somewhere... did you say 250 rpm for crank speed? thats borderline iirc. do you know any psd owners whos starter you can borrow for a few hours? bad computer?

The crank speed is fine. I heard around here that 200rpm shown on the tach is normal. Has to breach 600 to start, right? When i did drain the fuel bowl, i let it out all the way...dunno if that's bad. There was so much crap in there, looked like someone was making a vinaigrette.

[ridiculously_necessary]

thats a lot of crap. at this point i would think it couldnt hurt to pull the bowl out and clean it...

when the engine is cranking over...does the fuel bowl fill up?
