    7.3 IDI Cranking but not catching.

    It occurred to me that I could in essence check that the IP is receiving fuel (that the screen isn't blocked) by taking the fuel return off of the IP. I did just that however the batteries (a less than 1 year old pair of Oreilly Super Start Extreme 850 CCA) are dead, even though this thing has...

    7.3 IDI Cranking but not catching.

    I'm reading around 9V or a little lower at the FSS, does anyone know if that is correct?

    7.3 IDI Cranking but not catching.

    Good idea. I'll try that tomorrow.

    7.3 IDI Cranking but not catching.

    That IP has been leaking fuel since I bought it, 2 years ago... been kicking that can down the road fixing bigger issues. It's time I dug into that as it could use a dynamic timing. At any rate I'll give the tow start a go tomorrow if I can convince my neighbor to participate in the...

    7.3 IDI Cranking but not catching.

    I drove the truck Saturday and it started and drove just fine, filled up the diesel tank on the way home. Sunday I went to start it, I warmed the glow plugs until they began cycling, and I cranked it but it didn't catch at all. Gave it a couple cycles. Normally, if its cold (freezing or lower)...

    Crank no start with ignition key, with ignition key on and jumping the starter relay truck starts

    Thanks for the idea, makes sense to me however this is a new issue, it used to have no issues cranking and starting with the key before. I did notice that when cranking the engine with the key it'll catch a little bit as I let the key come back to "on" from "start". This makes sense to me as...

    Frankly IDIBRONCO, you're useless as a help and you're a *****. Stay out of my threads. Merry Christmas.

    Crank no start with ignition key, with ignition key on and jumping the starter relay truck starts

    I made another thread because the hints in a general direction were very unclear and instead of asking and hoping people would dig through that whole thread to help me, I decided it would be simpler and easier to start a second thread. You suggested a theory that I may have a bad DMF but gave...

    Crank no start with ignition key, with ignition key on and jumping the starter relay truck starts

    So that's what it has come to? You need to insult me because I asked you to clarify so I could better understand the system? You want me to return the favor? You must be one of those guys that is of the type of "don't ask me why just do it because I said so!!!".

    Crank no start with ignition key, with ignition key on and jumping the starter relay truck starts

    Thanks for the advice. Hooked up the IP to the battery positive with some wire/alligator clips and cranked it - it started right up. So I'm going to say I'm losing power to the FSS when I turn the key to start. No clue why although the ignition switch seems like a likely culprit.

    Crank no start with ignition key, with ignition key on and jumping the starter relay truck starts

    Yeah. That is the conclusion I have come to I just need an extra set of hands to test it.

    Crank no start with ignition key, with ignition key on and jumping the starter relay truck starts

    Look, I'm just trying to learn here. If you don't mind telling me, I do not understand what is "broken" here. How is that push button any different than what I already have? I have power to the FSS and I am causing the engine to reliably crank when I turn the key? In my mind the key is doing...

    Crank no start with ignition key, with ignition key on and jumping the starter relay truck starts

    Okay, that all makes sense except the engine is turning over just fine with the key. I don't understand how installing a push button start, to turn the engine over, fixes this. What am I not understanding here?

    Crank no start with ignition key, with ignition key on and jumping the starter relay truck starts

    You're referring to the that lever inside the steering column?

    Crank no start with ignition key, with ignition key on and jumping the starter relay truck starts

    Okay, thanks for the advice. Naturally I'm hoping I can avoid that by fixing the issue but if push comes to shove that is what I will do. By using the starter push button what am I bypassing? I ask as I wonder if that may be my issue. The neutral safety switch and the clutch safety switch have...

    Crank no start with ignition key, with ignition key on and jumping the starter relay truck starts

    Correct that it only starts with key on fender solenoid jump. Correct that turning the key to crank means it cranks well and fast but doesn't catch at all. When cranking with the key there are no intermittent or slow cranking issues.

    Crank no start with ignition key, with ignition key on and jumping the starter relay truck starts

    So my '91 is being a little funky. I resurrected an old thread looking for advice when I misdiagnosed the issue and will include that original post down below. Here is what is going on. If I turn the key, let the glow plugs warm, and then crank it just cranks and cranks and doesn't catch at all...

    93 7.3 idi crank no start

    Figure I'm better resurrecting this thread than starting a new topic. Trucks been sitting for a few days as the brake booster went out, replaced that yesterday. Went to start it today and it turns over real well but doesn't catch at all. I found the plug (plastic protector broke off) for the...

    Probably bad DMF?

    I wasn't tired of hearing it, I wasn't clear as to what actually classified as to a bad flywheel. Thank you for clarifying. I appreciate your and everyone else's insight. I am not a mechanic nor have I ever been, I swing hammers. I like those and will make a set. I have looked at a few guides...

    Probably bad DMF?

    Thanks for the help guys. I understand I may be annoying some of you and I respect that it isn't your job to help me although I do appreciate the advice and knowledge. Naturally, even though I'm getting the vibe it might annoy some of y'all, I'm going to throw a wrench in the works. We've...

    Probably bad DMF?

    Thanks. Yeah. I'm debating it... From what I can tell I can probably get a rebuilt transmission from $2200+ plus the Luk kit for under $400. That saves me probably $1000 in labor. If I was to get cocky and go this route, anyone have a recommendation for a good place to get these?

    Probably bad DMF?

    Gentleman, here's what has been done and what the symptoms are, I'm hoping y'all can help me solidify what this issue may be before I go off half cocked and have a new flywheel put in and the tranny replaced (one bad synchro, one on the way out) in the process. I have a '91 F250 with a 7.3 IDI...

    Power steering gearbox

    Yeah I went through one of O'reillys pullers getting my pitman arm off, second, with a lot of heat, was the charm. I don't have actual torches just one of those copper pipe soldering ones... must've stood there for a half an hour or more applying heat all around before it finally popped.

    Finally got around to testing, and then replacing the glow plugs.. 4 stuck.

    Spent so much time on this truck the past month I had to stop for awhile as I was falling behind on work... Pulled off the cross pipes so I could remove that cover on the flywheel today. Asked my neighbor to come over and take a look as he used to work on mining equipment. The mysterious rattle...
