Super Crunchy 7.3 Powerstroke cold start fix...fail...WIN!

7.3 powerstroke cold start no start fix for under $100. My truck would not hardly start under 50-60 degrees. I was able to fix the injectors before replacing them. Shimming the injector electronics back to factory clearances makes a world of difference.

My 03 7.3 was missing ,shaking like yours was with 7 unplugged and hard starting,until I shimed the injectors.now purrs like a kitten. Thanks for sharing.

[@truckrental9694]

Thank Eric for posting this video on your experience using my kit to shim your injectors . This is Robert from Truckrental on eBay. I own over twenty five 7.3 Power Stroke F450 most with over 200k miles, in my fleet. I have shimmed almost all without having to buy new injectors. The shim kits Instructions over time have been revised to help people to do the job better. 1. Remove valve covers and plug back in the electrical to the engine. Start engine and do a test by unplugging one injector at a time to check condition of your injectors. If you have a miss or weak cylinder, shim those injectors first. 8. Plug in electrical to Solenoids and engine. Start engine before installing covers and do a test by unplugging one injector at a time, if any have a miss, check wiring harness for loose connections or bad wiring. Thanks again, Bob

[@johnwythe1409]

Great Video! Glad you got the problem solved. I have same issue, but is different problem. Originally checked my GP relay, it was good. Replaced some glow plugs and injector seals. clearance was okay, changed a gasket. All plugs tested good, and seals looked good. Went back to the replay again, and it wasn't working. Turned out the control wire was loose. Some times if would connect and some times not even after tightening. Internally the relay was wore out and arced contacts due to loose wire causing intermittent contact. Probably put 20 years wear on the relay in one year. Low HPOP pressure can also cause hard/no cold starting, or wore injectors nozzles.

What an emotional roller coaster, been there done that lol! Just an FYI 7.3 guys, the glow plugs stay on for 2 minutes on the on position. No need to cycle the key once the light comes off. Would also not recommend trying to crank too early before the glow plugs have cycled, the cold diesel hitting the hot plug could really do some harm to them.

Thank you for that, I away's have to cycle twice to start mine when it's below 30, Next time when it's cold will leave key on for 2 min's & hit the key, It aways fires up on the 2ed key light goes out, just a light puff of white smoke & run for 3-5 min it run's great

Glad you got the truck running, but the smoke indicates that fuel was present, I am thinking there is an issue with the glow plug system. Bad connection, low voltage, etc. The driver side battery ground at the frame is a possible spot.

Sam Adams Educate yourself on subjects before attempting to educate others. When I was in the military MANY of our diesels didn’t use any glow plugs because they didn’t come with them. There are many newer diesels that will start without them also. Google it little mate when you’re not sure.

[@cencoast_7.340]

Sam Adams Cmon Sammy you’re better than that. We rarely had any problem starting our HMVVS over in Iraq when it was near freezing so when you tell us that any diesel needs glow plugs in cold weather you are dead wrong. I’ve got a 97 7.3 and if you know about these engines then you know when ALL other systems are working properly you do not needs to rely on glow plugs to start it. Just because your truck went through “this” doesn’t mean you’re on the right path to diagnosing others trucks. No need to talk anymore about this, as you learn more about what makes these engines tick you’ll start figuring this stuff out. 🤙

I need help on my 2002 f250 7.3 powerstroke i change a lot off parts starts and dies

[@gerald542]

Did you change your cam position sensor. I started my 2001 e350 one day months ago and it just shut off. It started up but it would stall. My mechanic said it could be the idm I said maybe, my current idm was looking bad so I changed it. Not saying I did not need a new IDM at some point but changed it and had the same problem it would stall. Changed the cam position sensor and it hasn't stalled since. $250 for a IDM or $30 for the sensor.

Thought you said it could not detect a code with scamners??

Can this performed on the 96/97 with mechanical pump?

If it's a powerstroke yes, if it's not a powerstroke and it's a 94 no
