I''m here to learn...I''m 61, worked with all kinds of diesel engines, but the Powerstroke & other Light Duty diesels are a learning experience for me @ 61 yrs. old.
I just installed a White-Rodgers glow plug relay. After watching this video great info thanks. Are you located in Livonia? I used to live on Robert Drive. I also lived in Inkster, Wayne and Romulus. Cant say i miss Dietroit.
Nice Thor's Hammer electrical proof testing. I just bought a 2000 F-450 with a dead glow plug relay. I live at 4500 feet and it gets very cold. A little time on the internet and it is my understanding that the OEM relay is undersized. The replacement that will last the lifetime of the vehicle is a "White Rogers 586-902" 200 amp relay. These are used for many purposes and are built tough.
I just put a White-Rodgers glow plug relay after watching this video greatinfo love the vids. I used to live in Livonia,wayne, Romulus and Inkster. Can't say I miss Dietroit though.
Cool !!! Helps me on my "Auction bought" f350 with 7.3 engine. Wouldn't start when they went to sell it but found that if you let it roll down the hill,(the day before) it would start. !!! :-) It was 29 deg. at the day of the auction.
Very instructive sir! I just bought a 2000 for my kid. I haven't had one in forever and all I did on that was an oil pump. I'll be subscribed just for extra random knowledge! Lol
“Not charging him to check the glow plugs”. Stand up dude right there. Most shops around here would charge to check them, then replace the glow plugs, then when it still didn’t fix the problem, say...”Well, the glow plugs weren’t at optimum performance, and because of that, the glow plug relay shorted out, causing them not to work at all” 🙄
Can both of the solenoids go out at the same time I have no power on fuel pump and no wait to start light. By the way great video I love the way you get right to the point
I know yout tested the Glow Plug Relay and it was bad, but how do we know if the Glow Plug Controller is any good? How do you test the Glow Plug Controller that sits below the Glow Plug Relay??
You either have California emissions & the module OR you have the starter relay looking that is the GP relay. One or thee other. You eliminate everything else if you have CALIFORNIA....no tests for the module....
Are you still working on 7.3 diesels I have one and would like to ask you a few other things about mine. I’m new to 7.3 diesels and mine is giving me some issues as well thanks great video.
1998 E350 here. Concerning the dashboard indicator light, with a failed glow plug relay will the dashboard indicator light still come on, or will it not come on. I'm just now beginning to start investigating why I have white smoke sometimes on startup and sometimes not. Love the van but Damn, really hard to change those drain valve all rings! Thank goodness my 7.3 has never left me on the side of the road after 300,000 miles. Are you able to open up that relay by the way and clean up those contacts? Excellent tip , good camera work too. Thank you, Subscribed!
Thanks 4 subscribing! Yes the light will still come on if the relay has failed. Make sure 2 watch the 7.3 videos i have. Itll show you the most popular causes for either white smoke[incomplete combustion]or just a straight up 2 check your glow plugs.
I have a 01 7.3 and found that my GPR wires that go to ignition solenoid in the harness was burned chewed and melted and the relay itself is extremely bad looking truck was ok took a hour trip and then battery light came on figured the alternator and changed it didn’t work was really cold to snowing etc kept checking things out turned out my IPR was bad or not working the sensor part was busted so changed that etc started up but not easy and damn thing wasn’t charging still ...swapped the alternator out and figured Shity parts store one etc and damn thing still wasn’t charging etc was chasing things like the signal wire on the alt with key on was only seeing 9 volts 🤷🏻♂️🤷🏻♂️ idk why.... my batteries are little low etc but should still see 12v etc started looking around and found the burned chewed up ones traced them back to harness behind the a/c pump on top that went to the GPR pulled boot off the main one and severely corrosion etc rust soooooo any way to fix the burned chewed end etc snd just replace my GPR if it tests bad
did you make the connector for the harness or buy it? I do a lot of work on a bunch of people's 7.3's. would love to have one in my tool box!!!! love the videos btw
What is that wire your testing stays hot all the time?? I neeed help. Key on or off ir stays hot .. I don't understand? What's causing it to always stay hot
Help! I commented on another one of your videos pertaining to this video here. I could definitely use your professional opinion and expertise regarding my 01 7.3
Unsaid, but an intermittent condition appears to most likely be the relay only sometimes working? PCM or oil temp sensor failure would tend to be be complete, yes? Also, you're sometimes getting a click but still no power transfer. Could that click instead be the intake heater relay in the front? You mention another glow plug video but I can't find it. My step father-in-law has been jumping 12+ power to the FRONT relay for a few seconds and then starting up successfully. He's been thinking that front relay is the glow plug relay ... but apparently he was inadvertently activating the glow plugs somehow I guess since those two relay do share some connections..
Arod, I really like your troubleshooting videos. How can I get one of those harnesses connectors to test individual glow plugs? Parts counter? Recently you showed cranking with the baloons on the Left/Right bank fuel lines to verify a stuck open injector. I suspect leaking injector as some fuel was tested positive in the motor oil. Do you have any other ways of diagnosing injector issues without having high cost tools? I have a late '99 7.3L with just under 200k mi., also hard to start below 40F, but will start if I use the block heater.
HI buddy how many pins does the connector have? check this one out and let me know if this is the right one www.amazon.com/OTC-6088-Connector-Harness-Testing/dp/B000OQJHXQ/ref=sr_1_8?dchild=1&keywords=glow+plug+harness+tool+7.3&qid=1588388241&sr=8-8
Awesome video man. I have a 2003. 7.3 powerstroke. Was doing phenomenal no matter how cold it got. Recently installed a TS 6 position switch. Suddenly my truck won't start. Was starting fine without it plugged in when the temp was around 10 degrees. Was almost 50 degrees yesterday and would only crank and blow white smoke. Took me almost 10 minutes to get it started. ANY help or advice would be appreciated!!!!
@@PowerStrokeTechTalkwARod not yet. Just found this video yesterday. I just thought it was weird that this happened out of nowhere. I have to plug the truck in now before I leave work and overnight. It just started this almost out of nowhere.
But i see two glow plug relays....does it matter if only one relay is bad and the other is good? I just replaced my gp -relay closest to the fan but which one should i have checked the front one or the bavk one?
Mine is hard to start while cold I have to cycle key like 10 times then starts. So today I put bigger relay on an its 70 degrees today still had alot fuel smoke come out exhaust does that mean I have glow plugs bad?
Friend called me and said his truck wouldn't start, temp was like 20*, he said he kept cycling the glow plugs, when wait light would go out he would turn key off and back on. I told him the wait light had nothing to really due with the gp's so just turn on the key and leave it on for about a min and them start it. Call me later and said that worked.
Hi I watched a video that showed this test light method before I started working on my early 99 this week. I had 2 bad plugs show on the left side, and tested them with a battery charger when they were out. Those diagnosed correct with 2 working, the other side I had 1 not working from the light test. I figured I'd replace all 4 while I was there as passenger side is more of an ignorant bitch to work on. when I tested them out I had 2 bad not just the one. The second one would spark when I put power to it but wouldn't heat up and glow bright orange like the other good glow plugs. My guess is if my multi meter was around the home shop this week that plug will show a reading but be out of the spec shown in this video.
I respect you as a master tech as a personal friend of mine who is one, be honest which one of the say 00 7.3 mid 6.0, or mid 6.4,( mid means mid used in the trucks) I know to stay away from earlier generation of the 6.7 due to.the twin turbo junk, which would you personally have if was going to have one for yourself, thank you in advance ! thank for the video to learn
PowerStroke Tech Talk w/ARod thank you, I found me a 04 I think it is don't have the ad Infront of me , but it's only got 90grand and some change and was wondering what your call would be, the owner said it was solid and has some " snot " of oil on the passagerside head , kinda figured I would need to do a head stud kit , anyways thank you again and please keep the videos coming, I enjoy your take on how to work and your own touch of how to get things done!
The module monitors the resistance of all the glow plugs and tells the PCM if one has faulted to turn the check engine light on hence California emissions
Would this cause a crank no start in general. Cuz this is my problem I’ve searched all over the net & RU-vid All right I’m at my wits end with this truck it’s a 1995 Ford F3 50 7.3 dually quad cab It’s Tabs Dad he run it out of fuel twice then about a month or so it started idling rough and not really want to start in the morning that went on for about a week or so then he was driving it and then it’s hard to drive and rough just as rough as it was idling then he drove it like that for about another month and then it he started having it to where it was dying on him occasionally then we were at a stoplight one day and it died on him and took her straight home then we brought it here why I’ve been working on it First thing we discovered it wouldn’t get enough fuel because of the tank selector valve so I tapped on it got it to work for the time being then we went to getting enough fuel pressure to the fuel bowl so we figured it he burn up the pump so we replace the tank fuel selector Valve and the fuel pump and also I took out all the injectors open them bottom part only and cleaned him come to find out one of them had a piece missing and one of them had a broken spring so I fixed it and put them back then we will get fuel to the bowl and all the cylinders were hidden but it just still wouldn’t run so I did some more research it some more tinkering and replaced die PR valve and ICP valve because my troubleshooting led me to believe that those may be a problem as well so so far it’s got a tank selector valve a brand new fuel pump ICP valve and I PR valve then we were able to scan it somehow or another we figured out that we could scan it so then we got a scanner and scan it it was saying high side was open on the driver side I’ll send u the codes So I troubleshoot it that and found the valve cover gasket was bad and we just replaced it back last year this time so what I did was I replace them both and I did a Home reading on the entire system and I have that as well I will send you and I follow that procedure and I ohms it out 3.8 For the whole system and I double checked the IDM and everything to that seems to be OK as of yesterday it ran for about a minute and a half it chugged really bad but it ran There’s proper amount of oil and a high-pressure oil pump There is enough oil in the motor there’s proper amperage in the batteries proper voltage in the batteries had to replace the starter because I guess us trying to get it to crank over the other day her but a week ago it burned up starter so we replace the starter and I will send you the last thing it showed because now I’m having an issue to get the tester to read it For no longer works on his old vehicles and have no way to scan them so if you know anybody that has an in-depth scanner to do it it’s it takes an OBD two that’s what it’s been updated to because I don’t know what else to do we done everything that I could fine as far as troubleshooting and what I can fine as far as the half ass manual so I can get here in there Here is a list of all I have checked or replaced: 1) changed oil and filter, checked oil level. 2) checked fuel bowl for the loose heater - good 3) checked fuel filter, changed it less than 1000 miles ago 4) check glow plugs out of the motor 5) checked all engine compartment fuses 6) checked wiring harness for frayed ends 7) replaced the ECP? (front sensor) 8) checked for oil on the ICP sensor - none 9) replaced several CPS's 10) checked HPOP it’s up to spec 11) changed both VC gaskets & checked harness.
Will a failed glow plug relay cause the SES (check engine) light to come on? My 2001 F250 7.3 has symptoms of cold no/hard start (have not tested relay yet) - and the SES light is on. This year of diesel did not conform to OBD standards, so a regular OBDII scan tool won't give me codes/info. (And I see 2 almost identical relays up there - you're testing on the one closest to the firewall. What is the one for that is closest to radiator - a few inches fore of the one you're testing?)
Question you mentioned no smoke coming out the tail pipe had it smoked what would have then be the outcome ? Im having a similar problem but I've noticed smoke not only in the tail pipe but the turbo as well any advice ? Thanks in advance
So I finally figured out how my multimeter works and took some readings off of the GPR. After turning the key the glow plug terminal initially read 0. Then after about 20 seconds I heard it click and got a reading of 11+ volts. It seems weird that there would be that long of a delay between the key turning and the relay activating. Do you have any suggestions? I plan on testing the glow plugs next to see if they are within spec.
great video. i have 02 7.3 that isnt doing any clicking or anything. power from battery but no power anywhere else reguardless of keys position. how do i go about getting PCM repaired?
Im very new to diesel this is a crash course for me . At the moment I can’t get my truck to start on 50degree day so im out of ideas its a 96 F350 im about to change the glow plug relay and see if that helps@@PowerStrokeTechTalkwARod
Having issues with hard start in temp around 40 degrees. Replaced the relay, starts a little better, but still get a lot of with smoke when it starts, suggestions?
