Ford 7.3 Powerstroke no start hot. long crank

With this video I show how a failed injector seal caused a no start hot, long crank. I did do the dual icp test. They were within.1 of a volt at all times. That normal variance between sensors. It fooled me and caused me to replace or warranty out a pump that I did a few months back. I also tried a known good ipr valve and jumped the ipr valve. I was stumped because the dual icp test passed. I removed the valve covers out of desperation and stumbled across the obvious cause.

It is amazing and humbling to think how many people this good man has helped and will continue to help. We still miss you; hope to thank you in heaven.

[@steveroelofs63]

What a fantastic teacher. Even though you left us too soon, you're still here teaching this diesel mechanic a few things. Thank you Sir

This is a fantastic video. You've created something that isn't just a procedural how-to, but actually walked through a diagnostic process. I've worked in several dealership service departments and I've never had a tech explain a diagnosis like this. I wish there were more tech's like you.

[@stitch1960]

I truly miss you Brother ! What a great vid

[@YahFllr]

you've help me in so many ways! your still my number one mechanic teacher today!!

[@mike-yp1uk]

thanks, its a good visual and will help to diagnose seal leaks. showing a shot of the scan data and brief narration helps to make things sink in. your skill and explanations make them great.

Ronald...you are not only good...but share which places you head and shoulders above others...you humble and helpful...THANK YOU!!! MY FRIEND HAS A POWER STROKE DIESEL...BEFORE IT MESSED UP...IT RAN SO WELL(Not sure if it's a 6.0 or 7.0 or 7.3 yet) he took it all apart did something to fix it...but now it takes all day(so it seems) to start...it will start but extremely hard to start...my friend has a very bad back and it killed him to work on it...now we are trying to find a reasonable priced mechanic that will help him out with this truck...we live in So Cal...(land of insanity) THANKS AGAIN FOR THESE VIDEOS !!! GREAT HELPS...

[@norman_sage2528]

What a "God sent" If I needed life saving brain surgery, then I would want Ron to do it.

[@vreference]

I had forgotten about your 5/8 wrench trick but I found the lower bolt is so long winded I was able to get more than a few turns in before it started pulling on the plate - it felt pretty safe to me and I assumed that was why the bolts were so long.

[@macksarf]

I decide to try to do it myself after i saw your video. The seal leak when start on a injector and it work well, forgot to drain so start it with no injector on, (SPILL) (get away) But work well. Thank you very much, you make me save a lot.

[@baddriversdotcom2922]

Excellent video and explanation of everything including tips. Got almost 200k on my 1999 but I think my issue can be solved with a fuel filter replacement (so I hope). Much appreciated!

[@raggedcat3406]

Hello Ron, I'm having a cold start problem. If I plug it in over night or just for 1 1/2hrs in the morning it start up fine. I have learn a lot from your video, I looked at your fix it for a quarter video and when ahead and replaced the valve cover gaskets with wiring assembly, replaced all glow plugs and glow plug relay.now the relay did had power the the valve cover plug on the out side. I did not see that gap on the inside plug, but when I started to unplug the injectors, the connectors was breaking apart. I full charged both batteries, and stills does the same, won't start. I have take in it to ford here in Hutto, txt and I was told I needed all 8 injectors. I have an old snap on scanner and done a buzz test and the sound good. A different shop told me if the injectors were bad it would run rough and be smoking. The truck run great, I just replace the fuel pump, pick up screen and cleaned out the filters on the sending unit. Any other suggestions?

[@robertwinterstein6690]

Great video I’ve had issues with the dt466e injectors. I like the inline 6 there alittle easier to work on than the v.

[@thefordmaniac]

remove the glow plug after injector replacement and then crank engine with it out to purge cylinder of oil and fuel mix.

[@justinsturm993]

First let me say your videos have help me a bunch in the past. But now my truck is doing the same thing the truck in the video does runs perfect when its cold as soon as the engine is warm the ICR is at 65 and won't rev up and no power I've changed hpop ICR ficm cps and a couple other things. Any help would be great.

[@22howards]

Ron, as always, another great video! Thanks for the information. Question, if one is torn would it not be prudent at this time to replace the seals on the other injectors? If you have done this repair on one injector what is the longevity of the other injector seals in your professional opinion? Thank you!

[@cbobcbob100]

excellent...bob

[@JosePerez-ki5zv]

My 2000 250 7.3 overheated and now it's hard to start up, what could it be?? Any help will be thankful

[@jmanwild]

Great video as always! I curious, Is it fairly normal for experienced techs such as yourself to replace an injector without a) cleaning the injector tip, and b) cleaning the injector bore. Personally I have only done a couple powerstroke injectors but with the sensitivity of the HP oil system, I took the utmost care in cleaning everything. Lastly, What is your opinion on oil selection for powerstroke owners. I hear so many differing views.

[@lopezo1313]

Would a bad injector cause pcm shut down crank no start, no fuel pump, no wait to start, no service engine soon, no scanner communication, no nothing... Checked fuses, relays, icp, fuel pressure ,hi pressure pump, valve solenoid... all good tested alone just no pcm communication. Started checking wire hardness. Disconnected 41-pin connection and I got pcm communication glow plug relay fuel pump, but no start disconnected..So I reconnect no pcm no wait to start no nothing. Can someone help I'm about to fix it with a $4 gallon of gas and a match.

[@dvgayle1]

Q: Is there a fuel loss at that one cylinder or multiple cylinders?

[@noname35ify]

I have a 2004 6.0. Can I do the same test with the valve cover off? Will it show a leak around the injectors?

Hi Ron I changed my fuel filter in my f350 03 and after that my truck running rough and lock it of power can u helping me with advice about this problem 😬?

[@jhayward1940]

Sorry to tell you but Ron passed away a while back. He was a good go to guy.

[@jomomma0739]

i have a 7.3 02 130k wont start replaced orings, turbo is leaking and white smoke out of tailpipe, runs 5 secs then dies and wont start any ideas thanks

[@omardinunzio5552]

check out PowerStrokeHelp on KZbin as well. Diesel Tech Ron has great videos and information however he was since past away. Sound like a compression problem to me. however watch the PowerStrokeHelp great stuff.

[@cdmc012599]

I've got an 2000 F350 dually, 7.3L turbo diesel. the only way it'll start is if I pump the throttle, the motor drags like a bad battery until fuel gets down into the cylinders, then it turns over easily(well a lot better). if it's hot I have to do the same thing. even if I start it and turn it back off then try to restart, still have to pump the pedal. I've checked both fuses and they are good, fuel pump on the rail is running. I even unplugged the plug at the top of the pedal and it'll start, but only if I pump the pedal, after starting the throttle has no response. any ideas as what I could check next and if so is there a test for it? thanks for any reply.

[@dancarlin5434]

Ron, Question, wouldn't a leak like that be indicated by diesel in the oil?

[@rickylakey4389]

Dan Carlin at 6.22 he will show you that it is oil in the area where the top o-ring is letting oil bypass and not diesel

[@dancarlin5434]

Ricky Lakey np, found that out when I did my injector cups. RIP Ron.

[@rickconnock7578]

[@ashleycox8465]

Should I remove the valve covers first, and look for the same problem?

[@wesleyrobinson7457]

Ashley Cox yeah probably the easiest way. Don't rev it with the valve covers off only idle
