Will Wd40 start a 7.3 IDI? Start tips cont.

short answer is no for me Wd40 didn't work

[@djpitr]

I remember my granpa would start his old diesel tractor in sub zero temps with a news paper :) .... he would roll them up like torch, light them up with lighter :) .. and hold them burning close to intake while cranking , worked every time

[@ramst3d]

@benz merc diesel runs on heat.... heating up the cylinders quicker by allowing it to take in hot smoke.... cummings still uses air intake heaters to start ( maybe have switched to glow plugs at this rate though.. haven't kept up to date..)

[@DannyWalker1949]

YES, It would work as we did this to. We would start our Heavy Equipment sometime in this manner.

[@AbcXyz-rn2lz]

Did the same with kerosene space heater in the 90s in -14F and took 20 seconds for instantly start. Used Howles to prevent gel

[@Friedrich-Wilhelm-1980]

@benz merc because the hot air make the fuel combust better a diesel engine heats fuel vaper threw compression but when the air is really cold or your compression is too low the ambient air needs to me warmer so when the engine sucks in the already warm air it can make it even hotter and then the fuel can ignite

Love your videos man... I have a 92 f250 non turbo... you are one of the most informative channels i have watched.. very knowledgeable, thanks for taking the time to make the videos.

[@akg8437]

I have two IDI’s, turbo and non-turbo. I have not been able to cold-start either engine with WD40 even when spraying a nice fine mist directly into intake manifold. I have rebuilt my NA and now with good glow plugs and 475 psi in each cylinder, no issue starting in 10 degrees Fahrenheit without plugging in.

I read the formula for wd 40 has changed to be less flammable?

[@C4soulja]

Mix a 50 50 blend of bacon grease and isopropyl alcohol. 60% of the time it works everytime.

[@Rene-up1dl]

Smells like breakfast when it starts 🥓

[@DannyWalker1949]

Back in the '50's & 60's and even in the early 70's Gas Rag's DID work and even WD 40 Worked really well on starting our dozier's and Cat Wagon's and ALL our Diesel Equipment. Now-A-Day's all the Old stuff SUCK❕ I've been try'n to start a '85 6.9 diesel and a '92 6.9 model as well. and hell, Noth'n is work'n except Start'n Fluid. Which I refuse to use, I've seen what it will do to an Diesel engine in the Cylinder's and Piston's and Piston Wall's..............Also, 0ur Diesel Now-A-Days IS Awful also.

i use white gas coleman camping gas on a rag works well

Good to know.

Hey Mike - I have been researching getting my 7.3 IDI NA on my 94 F350 started after sitting for a few months. How are you bumping that starter on the passenger side? I am troubleshooting solo, and climbing in and out of the truck to crank doesn't let me check for fuel/air leaks!

[@groundtogreen1140]

If you cross the two big terminals on the starter relay it'll manually engage the starter

[@matthogue5084]

@@groundtogreen1140 Thanks Mike! After I posted this, I started looking around and figured it out! I get back to the truck this weekend, hoping to solve my no start issue.

[@sethwoot]

I had a Cummins 4bt that had air leak and to start it i would use rag with white gas or Coleman gas fired every time

[@chewy-bu1oy]

Iv used a gas rag before it works but I don't thank it will work on one that has a turbo but iv stuck it over one that is none turbo and it started but it did smoke and knock like hell

Hey man, I need to replace fuel lines on my 7.3 idi, 1992. Do you know what type and size line I can use? I want to just run rubber/ plastic lines. Alot of forums say that if I use the wrong line it will get ate up by diesel. I guess since in 1993 they switched to metal lines there's not alot of info on lines for a 1992

[@groundtogreen1140]

high pressure lines have to be steel low psi ones you can change

[@fordguyaj5581]

@@groundtogreen1140 only high pressure is foward of the injection pump ? Is that right?

[@LMG6989]

High pressure feed lines are from the IP to the injectors and need to be steel. Low pressure return lines come in a kit from most auto parts/ diesel parts stores. I use to buy all my diesel parts from the local diesel shop since they also sold parts as well as work on diesels.

Mike, my truck has been sitting two years without starting, i have fuel at the filter and coming out of the filter but no fuel at the injectors , should i take the top cap off the injection pump and fill it up with diesel like to prime it ? thanks, Mark

[@groundtogreen1140]

shouldn't be necessary to removed that cover. How fresh is the filter? sometimes they can just be a little stubborn.

[@formosa41]

Using wd40 helps when you have fuel issues such as dirty or clogged injectors or a bubble in the fuel lines...etc. It's not really going to help with cold weather or bad glow plugs. To start a diesel in that situation, try blowing hot air down the intake while cranking. Either a heat gun or even a hair dryer will work.

[@groundtogreen1140]

Right on I basically made the video after several heated exchanges where people were swearing wd alone will fire a diesel off

[@theclintified]

I tried the wd40 today after working on my non turbo IDI and it doesn't work even without the intake on a warm day. I'll be trying starting/ether soon.

[@jamespimental6919]

wouldn't work on my 7.3 either starting fluid works every time

[@allanbell4111]

Mine starts off wd40 good but your not even spraying anof to crank it and either the worst thing u can spray in a diesel

[@userwhocantfindaname]

anyone try any other lubes like pb blaster etc.?

[@dravenwoods6704]

Use non-chlorinated brake clean

[@petedebo6906]

It won't work if you have the air filter in the air box which we don't see just the air snorkel removed the filter will catch the wd40

[@alaskanwheeler]

I know I could be opening a can of worms here, but...is there a proven "starter fluid", one that proves any better then the other?

[@groundtogreen1140]

I still don't have a direct answer for that as I have heard of so many methods it's not even funny. The general consensus seems to be one with a cylinder lubricant I think is how it's advertised. It's what I now use as a last resort.

[@supersportimpalass]

@@groundtogreen1140 hand held propane torch with a manual valve head works well. They changed the propellant in WD40 which is why it doesn't work anymore.

How hard is it to remove a turbo off a 94 IDI motor

[@groundtogreen1140]

If you've never done it before it can be a little tricky hardest part is getting the exhaust bolts off at least in the salty northern us. I have pulled quite a few so can get one off in probably about an hr taking my time
