I just wana give a shout out to that starter for staying in the game.😆

[@RevampMotors]

Still hanging in there, to date, she fires right up now. No more starter workouts

[@MrPoolman951]

Thank you for making this video. I’m having same problem with my 6.9 and I have ordered an IP. I was so happy to hear Red running.

[@RevampMotors]

Glad I could help!

[@blako4702]

Thank you for making this, like you said there are really no tutorials on how to do this. I just got a 86 350 6.9l with a bad pump so thanks for making this and showing how to do this properly.

[@RevampMotors]

Thanks for watching!

[@Depressed_Nightfury]

Damn you're cranking on that thing like it's slave lake 😂

[@RevampMotors]

Yeah, it was suggested I should have held the throttle open to help prime it. It starts right up ever since then though! 😀

[@Depressed_Nightfury]

@@RevampMotors yeah that would probably have helped. Just got my first IDI this week, pretty stoked sister learning about those since I came from a powerstroke

[@christianfrome5437]

@@Depressed_Nightfury just got my idi about the same time you did, yours a 6.9 or 7.3?

[@Depressed_Nightfury]

@@christianfrome5437 6.9 with a 4 speed, 84 F-350.

[@christianfrome5437]

@@Depressed_Nightfury Nice! I got an 85 4 speed F350 with the 6.9. White crew cab dually long bed

[@guychapman7735]

Overall very helpful. Thanks! A couple of things I learned the hard way: After having the ip out take it to a shop that has the tools and skills to time a mechanical injection system. Only 1 or 2 degrees will cause high temperature, heard start, smoke and loss of power. May even sound ok the a trained tech. NEVER HOSE DOWN A DIESEL WITH EITHER!!! 20:1 compression is not the same as a Gasser. The glow plugs will light either in the prechambers blowing them down into the block! A great video showing damage is: Why we don't use either in our diesel. With a 6.9. Also broken piston rings, and damaged timing gears. When loosening the nuts on the injector lines, hold the fittings on the ip with a wrench. If your ac is working, put caps on the high and low side Schrader fittings. The gas can leak out of a good valve if left uncapped. Good luck with your ride.

[@guychapman7735]

Having said that, if you feel you must use either, only a short sniff will do the trick. Be sure to DISCONNECT the glow plug circuit first! I've heard that WD-40 will work with out damage .

[@RevampMotors]

This is EXCELLENT info, thank you for taking the time and writing this! I will be sure to be more careful from now on.

[@psd28]

@@guychapman7735the information you gave, is generally a load of shit.

[@christopherkoa9512]

Cool thanks for the info and video

[@hailefire8087]

Just watched your video, man I was on the edge of my seat saying "c'mon Big Red" you can do it!!!

[@RevampMotors]

Still going strong, you can see how much better red runs in the clutch replacement video.

[@lenBrill1971]

Excellent video my friend. You are so much like me. 100% effort in showing us how too git er dun. Thanks

[@RevampMotors]

Thank you for the kind words, trying to improve all the time.

[@zclubofamerica]

Super CONTENT RJ ! Thanks for the video !

[@christianfrome5437]

Damn, I thought you were joking when you said low compression. I used that much ether on mine it would probably run away

[@RevampMotors]

After running it for a few mins, it runs a lot better now. It has been starting right up every time. I think I have it in my snowy days video.

[@MeltingRubberZ28]

I have pretty much the same truck. 85 F350 6.9 IDI Dump. It's been stalling when I push in the clutch and the revs fall. I've about had it with this truck though and ~$1000 for an injection pump may be the straw that breaks the camels back.

[@RevampMotors]

Check your inlet pressure before you replace the pump.

[@MeltingRubberZ28]

@Revamp Motors by R.J. what would be the issue if that was low? Pretty sure the tank pump was replaced not that long ago.

[@RevampMotors]

@@MeltingRubberZ28 the lower the pressure will pull back timing, on that diesel, there shouldn't be a tank pump.

[@MeltingRubberZ28]

@Revamp Motors by R.J. seems like it was likely dirty injectors. Put 1.5 cans seafoam in the tank, warmed the engine up, drained the fuel filter and filled with with pure seafoam. Ran the truck for about 90s and shut it off for 20 mins. Started it back up and it ran great, drove it for about a half hour around town. That's seafoams "standard procedure" for diesels. Worked wonders on my truck. Figured I'd share.

[@RevampMotors]

@@MeltingRubberZ28 That's great! I should do that at least once a year.

[@michaelbenoit248]

When priming the lines you should’ve just held it at wide open.

[@RevampMotors]

I will try that next time, hopefully it won't be for a long time. It's been starting right up ever since!

[@crlrealty1]

Can you ad in the description the size of wrenches and sockets needed for the job.

[@jakesjunkyard9892]

Did you eventually get it running better? And if so how?

[@RevampMotors]

The air worked itself out after about 5 mins. Still starts everytime with ease to this day.

[@christopherkoa9512]

nice work, how long did it take to do the entire job?

[@RevampMotors]

2 or 3 hours I think.

[@DannyWalker1949]

I see you're in Texas as am I. I'm in East Texas over close to Lufkin area. Are you gonna sale it or part it out by any chance I'd be interested in it for parts for mine.

[@RevampMotors]

It won't be for sale until I take the bed off and that will probably be a year from now. Right now it's the most useful truck I have.

[@adinadavenport20]

poor red

[@RevampMotors]

Still running strong

[@BGWenterprises]

Thats a hole lot of Devil juice to start. Glow plugs are far better for the life of the engine.

[@RevampMotors]

Red runs MUCH better now, I haven't used the juice to start it since.

[@sterlingwitherspoon5709]

I find it quite lame how u skipped over how to remove the passenger side Injection pump bolt. How do you expect the viewers to learn. Smh. Rookie.

[@RevampMotors]

Guess I will just have to make another video.

[@fordnut4914]

How you call someone a rookie if you don't know youself.😂
