7.3L no start no glow plug light

[@cindelmason8842]

For me it was a corroded diode in the fuse panel under the hood, number 37. Only part of the diode had continuity, which was why I missed it and why it checked good without actually pulling it out. Try pulling it out and then cleaning off corrosion off all of the diode metal surface. All fuses checked out, and plugs tight. Started right up. Hope this helps someone.

Thanks man you saved me, it’s currently 5am and I’m already late for work but for me I had the wait to start light but the heater was completely unplugged even came off the plate! I had no issues the day prior again thanks man you saved me

[@rvidernvtion9898]

thank you sir! after my 01 sat for 3 years all I had to do was replace the batteries and the 30A fuse you point out and it fired right up!!

Good deal

[@Davidlinsay64]

I have this exact problem I have a 1999 F-power stroke 7.3 and the trunk worked fine I parked it for about a week and went to start it and the light on my dash did not come on! I thought it was the relay but after watching this I am sure that is my problem! This video is a true gift to me Thank you so much! I love KZbin there isn't anything I can't fix because of videos like this! Have a great week! Just subbed Saved me lots of time!

[@krichards8472]

Thank you so much for your Video. you saved me a tow truck and a ford gouging. and thank you Doug for the tool you gave him, I will make one too. Great video of show and tell. could not have been any better . right to the point NO BS added .Mine is a 99 7.3. mine acted up from just putting a new filter in . once you told me about the fuse I put the new filter in 3 times and blew 3 fuses. put the old filter back in and ordered a new filter from some one else. so far all I had to do was change fuses. but now I know what to do when the element goes. Thank you so much for your free info. you made it easy to find the right fuse rather quickly. and I am going on a 2000 mile trip next week and didn't want any repair issues. I beleive in the old truck fix too, very good point. Thank you Chris for your teaching on this video I am #370 thumbs up

[@andyskarda5220]

Thanks for this video this also saved me a lot of time and money. Easy fix and I was thinking the worst. The only issue was a bad fuel bowl heat and I never new it existed.

[@stanwalls6434]

Nice tool but I just use my channel locks opened wide, never had an issue, had that same fuse go out on mine at 400K miles, I was driving 1st time it ever left me on the side of the road. Thanks for taking the time to make this video👍

[@pesb18champ11]

Thank you so much for your video man because of you I’m able to get my truck back on the road and working making money again today. Thank you so much.

[@squirrelymann6545]

Bro, thank you so much for making this video - My 99 had the same issue. I replaced my Glow Plug solenoid relay 1st , no fix - then changed out my oil temp sensor, no fix. I was at a lost then found your video - The fuse was blown - replaced it and now it’s fixed.

[@michaelgriswold1156]

Thank you very much for the video. I had just replaced the fuel filter for the first time after purchasing a 99 F350. All the sudden that night I started it and it shut off abruptly. Your video helped tremendously. I did exactly what you said and I am back on the road. Thank you again!

[@hirambarker8430]

DOOD!! Thank you so much! I feared the worst, but you made it a five minute fix. I didn't replace the heater, just the fuse. So far so good.

[@340kustoms]

I have a 1999 F-350 and had the same problem today. I am so glad I found your video. I found the 30 amp fuse blown and was looking up what was connected to that fuse. Found your video which was the help I needed. I always try to do my own repairs. I like to know there completed right. Thanks again and you can bet I will continue to watch your channel.

[@chrisward405]

Thanks!! Much appreciated

[@davecalvo6418]

Just a note to everybody, you can pull the white connector plug off that is located just to the left of the bowl which is for the heater and then replace the fuse to get yourself running in a jam if you don't have time to replace the element. That heater is really design for super cold temps and if you are not located in Alaska or someplace crazy cold you can probably run without the element

[@ludwig-vi6pi]

Thanks for the video got her done. Late 99 f250 same problem after a long trip and sat for 2 weeks no start. 👊🏼

[@cliftonwhite1501]

Chris this video has truly been help to me , I have a 99 7.3 I been buying boxes of fuses at a time (30)amp for at least 2 years. Put the truck in the shop $1600 later still doing the same thing but with the video you shared I’m back on the road again.... Thanks Chris

[@chrisward405]

Glad your back running. The 7.3s are pretty simple. Hardly anything goes wrong with them. If you ever have an oil leak check the top of the engine first in the valley. Seems to be where 99% of the leaks occur.

[@2020HotShotTruckingLLC]

That fuse also feeds the PCM. I just bought my 3rd E99 for my HS business...that wire was removed by the resident rat. On my long list of repairs to do after ball joints, rotors, calipers, front bearing assemblies. And install my flatbed of course. Enjoyed your video!

[@chrisward405]

Agreed. I'm glad it wasn't the PCM

[@2020HotShotTruckingLLC]

@@chrisward405 That's a common problem. Don't much need them here in GA, but I'll fix mine soon.

[@chrisward405]

@@2020HotShotTruckingLLC if you are out on the road when fails you can unplug the heater and change the fuse and keep on trucking

[@DIYWellcraft196]

I use a pair of pliers and a extention to remove the fuel bowl filter cap, just flip the pliers over and everyone has a set of pliers but not a friend that makes and sends free tools :)

[@dougmatheny854]

Glad the tool worked for you didn’t think you would need it that soon though! Nice informative video on that repair, my 2000 7.3 has 180k I’m sure I will be replacing mine soon.

[@chrisward405]

Thanks again. Tool works awesome and I wasn't expecting to use it right away either lol

[@golfingderrick]

This is exactly what the problem was. Thanks for the video

[@earlstacey2709]

I see that you can just unplug that heater on the outside of the filter housing if you are in a jam. Probably don't need the fuel heater at all if you are only in warm climates. But it can at least get the fuse to stop popping until you can get a new heater installed

[@chrisward405]

Agreed. Meant to say that in the video but didn't

Check your number 19 fuse on a 2000 Ford excursion diesel just literally happened to me and my brother-in-law told me to check that fuse after looking everywhere on the vehicle and that fuse is blown out said it he had that experience on other 7.3 diesels.

[@lords2112]

depends on the year..a 2000. the wait to start being out is..glowplug relay shorted,intake heater shorted..which blows the big 30amp fuse under the hood by the air cleaner housing..remember depends on the year.

[@alexkalsatos5555]

Thanks for the informative and very well explanatory good video. I too have a 7.3L and the glow plug light doesn't come on but I also don't have the crank kicking in. I bypass the starter with a push button cranks no start have you ever had a situation like mine? Any help is appreciated.

[@maryadams6415]

How does the FBH tie in with glo plug and a no start condition. I am fighting this on an 02.GPR had no power to it's always hot lead.If use jumper cable and hook to one batt and the put positive on the GP relay, rh side where power goes to inj harnesses. Now glow plugs work and after 1-2 tries, she starts. New tank fuel pickup assy. new Bosch fuel pump, Motorcraft IPR, new icp, new ecm, it burnt out 8 weeks ago, IDM check and PHP hydra chip also checked. Heading to shop tomorrow IF we can get her started. I do have glow plug light that goes out after a few seconds, as usual since new. Wha is up here?

[@wilsonashton4134]

Great video! Very informative and understandable!

[@billmalec]

When my Fuse 30 blew because of the heater, the THEFT light flashed fast also which left me to think my key wasn't detected or there was something wrong with the Theft system. I did narrow it down to the fuel heater only after I found out #30 was blown. I just disconnected the heater outside the bowl at the connection there. Replaced the fuse and it started right up.

[@RiggyRonnie]

Ohh, same thing happened to me, luckily I had a massive pipe wrench and was able to grip around the plastic cap on the fuel filter and get it replaced

[@richardpatrick7131]

My 7.3 has been running great but this morning pulling around the yard to hook up my trailer the truck quit. It cranked back up so I hooked trailer and got down the road quarter mile and it quit again so I turned around went back home. I drained fuel bowl drain it and it started backup. I let it idle for about 5 minutes and went to press fuel pedal and it quit and never would start back. I noticed my wait to start light would come on and I checked fuse and the 30amp was blown. So I guess I’m gonna replace what you just done. Thanks for the video

[@chrisward405]

You can test it by unplugging the wire on the outside of the fuel bowl to the heater. If the truck stays running then the fuel bowl heater is the issue. Hope this helps

[@stevecarlisle3323]

That fuse in this video is the fuel pump mounted on the frame. If you feel the fuel warmer is at fault, then just un plug it. Not likely as it is controlled by the PCM when temp drops really low.

[@chrisward405]

Agreed. But the fuse controls other things as well ( fuel related).

[@stevecarlisle3323]

@@chrisward405 For Sure. The wires to the fuel bowl heater are not 30A wires. Fuel heaters fail open, not shorted, similar to glow plugs.

[@chrisward405]

@@stevecarlisle3323 100% correct. I could have unhooked the wire at the back of the fuel bowl and changed the fuse and it would have ran. I wanted to put that note in the video and forgot to.

So I’m having the same issue no wts light no start but I have an aftermarket fuel pump on a 96 7.3 I’ve checked everything new gpc all fuses are good none loose pcm is getting power to where it should I’m stumped no lose wires or anything I know I have a bad glow plug and one weaker then the rest but that shouldn’t be the issue but I’m replacing them all and new valve gasket soon I don’t know what else to do should I check my heater even tho it’s ran off an aftermarket fuel system?

[@chrisward405]

You can unplug the fuel heater and double check the fuse. If it won't start after then there is another issue

[@beyourownhomepro-1915]

Great video man!

[@vietmanesemechanic6331]

Could it loose fuel pump power too? Same fuse? Because i have fuel gauge and both no fuel pressure and no glow light

[@chrisward405]

Yes. You can unplug the fuel bowl heater and replace the fuse to see if that is your issue. The truck will have pressure after these steps are taken

[@williamlarimer2163]

I have a 99 it did start but while I was on side it shut down for no reason yes I have the same problem with #30 fuse however I don't think that heater alone will stop it from firing . I'm not Shure but I'm thinking it may be tied into the electric fuel pump or injector relay which I'll shut the fuel system down as well

[@williamlarimer2163]

So to update on the thought of the fuel heater and to eliminate possibilities I simply unplugged the fuel cup at the base where the heater gets power from put in a new fuse and it fired right up. Now I know it was the heater and not something else
