Just some feedback about your repair videos. Thanks they are truly inspirational. I believe as you do... Don't be a parts changer. I want to know why my car doesn't work so I can better understand it. Your videos help in that respect, Thanks.

On a note about a recent fix. I recently gave my Jeep WJ a full tune-up. It fired up great and ran perfectly. When I shut it off she would only crank, not start. No trouble codes. After it cooled she would start and run great. After it warmed up and either stalled or I shut it off; she would only crank. I went back and forth for a week on this. Even watched your video on a similar scenario. I was not prepared to call it the PCM. That was replaced a year ago. I checked for spark after it warmed up, and would not start, and spark was present. I used the Noids to test for the fuel injection signal, it too was present. I found it hard to believe the injectors were bad, they are new. So I ohmed out my injectors when hot.and they were all 3 ohms higher than manufacture specs. Yet when cool they ohmed out correctly. I replaced the injectors with my original ones and the Jeep runs great, no issues at all.

A lesson learned about buying cheap parts. You buy cheap and that is what you will get, cheap. There wasn't any trouble codes, suspect, because everything was working... except the injectors releasing fuel.

I thought this may help with one of your classes as another potential cause of a problem, research all angles.

Thanks again. Keep the tips coming, they do help.

Hey Paul my Name is shaun Gous 56 yrs old and have been a sparky all my life. I'm loving the leasons and still learning at my age. Keep up the good work , all the best from Aussy.

Paul, I’m not sure if this will get to you or not but I’ve been meaning to write this for a while. I’m 43 and been working at the same trucking company for 20 years. About 3 years ago, I decided to make a switch from driver and go work in the shop. I’ve always worked on my own cars but honestly I didn’t know shit. I got to the shop and quickly realized I had to learn how to diagnose. I was amazed that quite honestly, even the couple old timers were just part changers. I found your channel, bought your book and got your premium subscription. I’ve learned so much from you and for the first time in my life I actually enjoy my job. I’ve become the go to diag guy in the shop already. I still have so much to learn and it sometimes is real challenge retaining so much info. I really just wanted to say thank you so much for your all your hard work because without you I don’t think I could’ve made it in this field.

Truck driving through Pennsylvania right now wish I had time to stop and say howdy you and your brother and Caleb y'all do a great job
