    Engine Running Cold

    Thanks for the information! I'm debating pulling this replacement thermostat and checking it. Probably best to do, however, after reading that other thread that's going on right now I'm starting to wondering if my old thermostat was causing my truck to warm up abnormally fast in cold...

    Engine Running Cold

    Okay, I picked up the laser temp gauge today and did a little test. After driving around for about 25 minutes I pulled it into the garage, turned it off, and shot the upper radiator hose. Reading about 140*F. I'm going to guess the thermostat is stuck open. I have a replacement Motorcraft...

    Engine Running Cold

    Apologies, forgot to include the other information on my truck. I do have a pyrometer that came with my turbo kit that is installed. Climbing a medium grade at highway speeds I sit around 600*F on the EGT gauge, cruising is closer to 300*F. Temps on the dash coolant gauge are pretty steady...

    Engine Running Cold

    Will order one, nearest harbor freight is like 2 hours away. I have some semi cheap gauges on order for coolant temp and oil pressure, I will install those once they get here. Also have another thermostat coming in tomorrow, however, I'll probably get the gauges on first and see what they say...

    thanks for the clarification. Yeah, I'm going to get a coolant temp and oil pressure gauge on it.

    Engine Running Cold

    It was usually fine last summer however I think the thermostat was stuck open for about a month as there was a little while there is was running cooler than normal (both on the gauge, by feel, and I think by power). Mind clarifying the whole leaving the radiator cap loose thing for me? Always...

    Engine Running Cold

    1.) Yeah, I'm going to test this thermostat when I pull it out. I'll probably wait for the new one to show up so I don't have the truck in pieces again. 2.) I'm wondering if that cold circulation could be sufficient to keep the engine from reaching temperature?

    Engine Running Cold

    Yeah, I have boost and pyrometer. Could use coolant temp and oil pressure.

    Engine Running Cold

    Thanks. Yeah, I was kinda hoping for the sensor to be bad, but I just took the truck to town and back (15 minutes and about 10 minutes at high idle to warm up). Drove the **** out of it, pulled it in the garage, shut it off, popped the hood, and the upper radiator hose is closer to warm than...

    Engine Running Cold

    My engine was running colder than normal, but erratically. The temp gauge would move around more than normal ranging from the N to the hash mark by cold. It used to sit at N once up to temperature and only go above that if climbing a long grade under load. At any rate I replaced the thermostat...

    Thanks for all the info guys.

    Rebuilt Injection Pumps and Injectors Sourcing

    Thanks for the info! Am I correct in thinking getting pumps and injectors from one shop is best as they are optimized for each other? Am I okay just replacing the pump and the injectors down the line, or should I do the pump and injectors at the same time?

    Rebuilt Injection Pumps and Injectors Sourcing

    I know the big four rebuilders mentioned around here are R&D, Moose, Russ, and Classic Diesel Designs. I've been hoping to pick up a 80CC pump and a set of injectors from R&D for a month or so now but haven't had any luck catching any in stock. R&D is relatively close by so the whole support a...

    Thanks, I'll give that a go.

    Fuel doesn't stay waiting at the injectors?

    Two theories here as I have found a similar starting procedure works best. First, maybe its putting some fuel into the cylinders and preheating that a little bit. Second, you and I may both have a really minor fuel drain back issue, so were bringing the fuel up to the injectors so it's ready...

    7.3 IDI Cranking but not catching.

    The ol PoS is running again. Oreilly's gave me 2 new batteries for free, they wouldn't give me my money back so I could go for something better. Put the batteries in and cracked two injection lines at the injectors, one on each bank. Had my neighbor Bryan come over, he's a good dude. He stood by...

    7.3 IDI Cranking but not catching.

    I'll run the test and see if any fuel comes out of the IP fuel return fitting once I can. I don't think that's the issue though, fuel filter looked clean, for all that's worth. It has less than 5k miles on the filter.

    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...

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

    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...
