  1. 94-98 7.3L General Powerstroke Discussion
    I recently purchased an amazing 1997 Ford F-350 diesel. There is a "switch" on the dashboard, and I have no idea what it is for. I have looked online, looked in the manual, and reviewed 15 years of maintenance logs; all with no indication as to what it is and what it does. It definitely appears...

    Hi, Like the title says, 2002 w/7.3 misses unless I turn on key for 20 min before start. If I just attemp to start it normally, it will fire right up but runs crappy like it’s missing on a couple cylinders. It’s lost a bunch of power because of this so I cannot drive it into town safely (Austin...
  4. E-Series Van Discussion
    Hi folks, I talked to Dennis @ strictly diesel about doing the hutch mod to my 2002 e350 7.3. He said "there is a pan surrounding the pickup that prevents the extended return from fitting. We also don’t list this kit as fitting the van because the van fuel tank has a liner that is notorious...

    I have an early model 99, has a TS6, 360 thrust bearing, straight pipe, the usual. What turbo would be a good recommendation that doesn't include endless fabrication, I do metal fabricating but it's my daily and I can't afford to have it off the road for too long. Looked at an H2E and other...
  8. 99-03 7.3L Powerstroke Problems
    Howdy Guys. Me and a friend installed a set of stage 1.5 sticks last week and i cannot get the truck to start. I'd say we cranked for about 1 hour, the batteries ended up dying. We put a jump pack on it and realized we didn't hear the fuel pump. We then tested the leads at the pump and didn't...

    While I was on a backup drive looking for some 2002 wiring diagrams, I ran across this 1999 Workshop Manual. I am going to post up here for anyone who is interested. There are 12 files. That means three posts of attachments - including this one. Anyone having a need to respond should wait a few...

It does always start but I went on a trip for about a week and came back and it took a few tries. it sounds like its dead but on about the 3rd try it comes to life and...
  11. 94-98 7.3L General Powerstroke Discussion
    Hello everyone!! I'm thinking this could be helpful to people thinking about becoming the proud owner of an OBS powerstroke, who aren't total pro's when it comes to the ins and outs of these engines/trucks. Hopefully this can become a safe place to ask some questions specific to these trucks...

    Until 2 weeks ago everything was good, but now if I drive the truck & park it, I can turn if off & it will restart immediately. If I wait 15 minutes it will crank but won’t start again for hours. Only one time has it stopped running while I was driving, only to restart after the rollback ride...

    First post for me, I'm planning on buying a hydra chip here soon. I currently have a six gun. I like the gauge the 6gun offers but im not a fan of the chip. Is it possible to run a hyrda chip with the banks 6gun gauging hooked up? IF so let me know how. THANKS!
  15. 94-98 7.3L General Powerstroke Discussion
    Good morning all! I am in the process of checking my oil pressure on my 95 7.3. Plugging my gauge into one of the ports by the valve covers, I'm getting about 6-650 psi at idle and when I floor it, it goes up to 2,500 psi for a few seconds and then drops to 1,500 psi. Is this normal? Thanks!

    Hey, i'm looking to buy my first truck and was wanting some input from people who know a bit more about these trucks. I am looking at a 2001 F250 XLT 7.3 powerstroke with a dumping flatbed. It has 250k miles. It is listed for $6000. I have asked some people and one said no way, that is way...
