    No Start after 3 days off

    Due to the fact that he has to wait 3 days between troubleshots, this could last for a while. However, one way to check for lack of fuel or air in fuel is to let it set for the 3 days, then while someone cranks it, have someone else open the schrader valve on the driver's side of the fuel filter...

    Still stumped over '94 PSD

    That's just it Double S. With the IPR diconnected the HPOP pressures were much lower. Plus, I put an oscilloscope on the IPR signal from the PCM and had a valid signal that looked just like Ford's documentation said it should with the exception of amplitude. That was something their...

    Still stumped over '94 PSD

    Well first of all, thanks to all who have tried to help. I really appreciate your time and sharing your experience with me. One of my pet peeves though is not posting a resolution once it was found. So in the spirit of non-hypocrisy, here goes. Got the new CPS and cranked it without the GP...

    97 f350 CLUTCH PROBLEM

    When you talk about bushing relpacement, are you referring to the one inside the cab that connects the pedal assembly to the master cylinder push rod?

    Still stumped over '94 PSD

    Well, I may have just answered my own question. I went back out, unplugged the CPS and cranked it. What do you know but the tach jumped up to the same exact place. Off to the parts store I go. Cross your fingers.

    Still stumped over '94 PSD

    Nope wires are good. I watch the signaling all the way to the PCM. They look the same from end to end. The IPR duty cycle at crank time is only 15%. I'm not sure but I think that only translates to something just over 500psi. I just noticed something else though. I went out and cranked it...

    Still stumped over '94 PSD

    Thanks jfinch, that reminds me of another thing I've left out. Three different IPR's. One of them brand new as well. The '94-95.5 pumps require an IPR with the edge filter. One of those was the new one. The newly installed '02 pump does not have the edge filter in its IPR.

    Still stumped over '94 PSD

    No Mike. No smoke at all. BigRigTech, I capped off the lines to help eliminate injector o-rings as the sole cause of this problem. I figured that if I wasn't seeing sufficient oil pressure with it capped off then I certainly wouldn't with it connected to the heads. Does that thinking seem...

    Still stumped over '94 PSD

    Oh yeah, you reminded me. Yes I've tried another PCM same exact result. Pulled the IDM and slapped it into a '97 and it fired right up. Got a stick shift so selector not an issue. The diesel shop behind our shop told me that if the oil pressure is below 500psi while cranking, the injectors are...

    Still stumped over '94 PSD

    I bought this '94.5 no run and thought I'd simply wave the magical mechanical wand and have it runnning. Well no such luck. After a month and a half, It still isn't runnning and doesn't act like it wants to. I'm not getting sufficient oil pressure while cranking for the PCM to tell the IDM to...

    Fuel Filter

    Well a couple of things that I think I see in your pic. First, it looks like your filter is not rotated so that the red tabs snap into the black lid. May not be an issue for you. As the filter sits, out of the fuel bowl, it will move around. It's not that tight of a fit. Secondly, the gasket in...

    HELP

    Are you talking about blue smoke by any chance? How many miles on your rig. Are there any mods to it?

    Coolant leak

    Sorry Mel. Excursion is what I meant to type but had brain fart. On the Excursion, pull the P.S. battery, remove battery pan, then the 3 or 4 bolts that hold the reservoir in. Pull out the reservoir and then pull the pump out of the reservoir. Install the new one in reverse order. Thirty minutes...

    Coolant leak

    Mel, Which rig are you workin on? If it's the expedition the washer reservoir isn't that bad.

    No Start ... any help truly appreciated

    If you are getting fuel to the injectors, you should be seeing white smoke out of the tailpipe while it's cranking. Especially if you've cranked'em dead. I would say if you have no white smoke, you have a fuel delivery problem. Hope I didn't miss this detail earlier in the post.

    Just a bunch of old women?

    Be sure and grease the radiator sprocket while you're in there.

    HELP! Fuel leak

    Bless your thumpin' gizzard, Mel. Nothing like a little humble pie for your troubles. I've been eating a lot of it this week as well. Sounds like you're on the downhill side now, though.

    New guy with ????? on 99 7.3 ps miss

    Acutally they're not the same test. A buzz test is done KeyOnEngineOff (or KOEO) and tests the electrical side of the injection system possibly revealing wiring continuity problems, IDM problems, or injector problems. It's an audible test to see if an injector is weak or not functioning for...

    7.3 L oil dipstick gasket replacement

    I guess I'l take the bait on this. Not sure what year you've got but the one I attempted didn't turn out as easy as I had hoped. There is a large o-ring in the inside of the dipstick tube connector. The hard part is keeping the inner piece from falling down into the oil pan while removing the...

    Has your truck set any DTC's that might clue us in? Did you use aftermarket CPS or one from Ford or IH?

    HPOP question

    i know that the early model pumps '94-95.5 had the anti-drain back component in the pump itself. Is that component a part of the HPOP resevoir housing on the later ones?

    HPOP question

    Thanks for the help, guys. Are the resevoirs the same as well? That came up as a possible incompatability on another forum. Any thoughts.

    HPOP question

    Does anyone know if a late '99 model HPOP will work in place '94.5 HPOP if the IPR is switched out as well. I'm needing to replace my '94's HPOP so I'm trying to find out what's compatable.
