    Wrecked my injectors/HPOP...

    I have never changed the CPS. Got the truck home today, dealer was saying it was missing on cylinders 4 and 8, I am assuming this is the contribution test they were talking about. Seems to run ok, I will drive it like I stole it and see what happens, at least I'm close to home. Can anyone...

    Wrecked my injectors/HPOP...

    I got word back from the dealer that the tech did some work to it and I might be able to "limp" it home 100 miles... Sometimes it wouldn't start at all and when I say lope I mean that it wasn't slight it was huge! Injectors were replaced just under 100K miles ago by the previous owner...

    Wrecked my injectors/HPOP...

    Guys, Looking for a little help on diagnosing a problem with my truck. I ran my truck low on oil (4 quarts) due to a slight leak from my rusty oil pan. I dont drive the truck much and knew enough to buy some oil for my trip last weekend but was too stupid to not check the oil... I was...

    Brakes locking up

    The pedal does return. However they stay slightly on. If you give it a little throttle to get the truck moving and get off of it the truck will stop. While driving it like this you can hear clicks coming from the pedal area and it feels like the brakes release slightly. I found a reman...

    Brakes locking up

    I found this thread exactly explaining my issue with my brakes locking up: http://www.superdutydiesel.com/forums/911-diesel-down/23790-brakes-locking-up.html It looks like the hydroboost is to blame. What is all involved in changing one and what year trucks will fit mine. I have an...

    No power to fuel pump

    Does anyone have a manual that can look what is between fuse 19 and the fuel pump? What controls the fuel pump, a relay?

    No power to fuel pump

    I have been working on a low fuel pressue issue with my truck. I did verify the pressure with a gauge and it was only 20 psi. I figured that the pump was bad so I replaced it. Still only getting 20 psi. I then looked at the FPR. Found the O-Ring that seals the brass cup was all smashed and...

    Fuel Press gauge install

    Joe, The isolator has a sticker on it indicating "Gauge Side" and it is the side without the Screw. According to the install directions, the isolator is held screw side up and then that screw is supposed to be loosened and the fuel pump cycled until fuel starts coming out and then retighten...

    Fuel Press gauge install

    I bled the fuel line to the point where I had straight fuel in the line and when the fuel pump shuts off I don't have any bubbles going back toward the fuel filter. Pressure on the gauge still reads 23psi or so. The only way to add coolant is to remove the fitting on the isolator, correct...

    Fuel Press gauge install

    With the fuel pump running crack the fitting at the isolator until only fuel comes out? Is this what your saying?

    Fuel Press gauge install

    I finally got around to hooking up my Diprocol Fuel Pressure gauge this morning. I installed it with the supplied Isolator and filled the cavity with antifreeze after I gently pushed down the diaphram in the isolator. I am only getting a little over 20 psi of fuel pressure. Is there a special...

    UVC harness pinout

    Well I got it running. I only had 4 injectors working so I sprayed a little starting fluid in the intake and fired her up and reved it up some. It blew som black smoke and then a couple of dead injectors started working, then they all worked. Maybe I ran low on oil (I was 2 quarts low) and...

    UVC harness pinout

    Everytime it gets above 50 or so I have tried to start it. The way the truck went away slow over a few miles makes me shy away from the blown fuse, but I will check anyway. I will be going into the valve cover this weekend to see if I can figure out what the hell is going on. The truck was...

    UVC harness pinout

    No light came on as power went away. The truck seems to want to start and I have had it start for like a second once since then but would not stay running. I get some nice smoke out the exhaust while cranking so something has to be getting fuel I would think. Will the truck start with only 1...

    UVC harness pinout

    Googled it and found this info for the plug: GGIICIIGG G - Glow Plug I - Injector + C - Injector - Ohms between the G and block Ground should be 0.1 - 2.0 ohms. Ohms between the I and C one at a time if one or more is > 5 ohms, it will point to the side's gasket connector or UVC harness...

    UVC harness pinout

    Just to make sure it was working I used a jumper cable across the relay, still didn't start. I'm pretty sure the relay is working though, i can hear the tone of the fuel pump change slightly when it turns on. I've had this fail enough that I can tell when the tone doesn't change that the relay...

    UVC harness pinout

    I have an old thread in the 7.3 power and performance (accidently put in wrong forum) for my truck that died. Back in December I was towing my snowmobile to a friends house to go play around. Along the way over about 5 miles I was loosing power bad till the truck would barely idle and then...

    99 7.3 Won't start

    Well tried the oil, I was 2 quarts low. Didn't work :( I bought 2 new batteries and will try them tomorrow. If that doesn't work I will investigate the under the valve cover harness. I was in there a year or so ago replacing all 8 glow plugs. I seem to remember an upgrade to the wiring...

    99 7.3 Won't start

    It's been over a year since it's been changed. I haven't checked the level lately. I only put 2000 miles on it since the last change. The truck has been doing Vacation Only duties since Diesel was so expensive. I will check the level and see what it is at. It makes good oil pressure when it...
