Chevy Van Injector Circuit Faults

- It was supposed to be a simple diag for a lean code. But when you get there the story has some other chapters to it. A P0201, P0203, P0205, P0207 and, oh yeah, it misfires too. Intermittent loss of power to left side fuel injectors, a slight hiccup in my diag procedure and positive diagnosis in the end.

Thank you! Finally someone that speaks English on a video like this! And shows the actual repair
Some days I just miss the old days of carburetor engines, simple and easy. Great vid and good to see a video come out from ya.
Thanks pal
Thank You, Corey! Had the same problem with my wife’s 2016 Chevy Express 3500. Three different mechanics looked at it, changed catalytic converters and still wouldn’t run properly. I found your video, got the correct replacement part and took it to the shop for installation. I believe they were surprised when it actually worked. 😂
Thanks Again.
Wow! Thank you! 🙏this is the exact issue we have over here on a 2015 chevy school bus with the 6.0L ......exact issue 👌
SI express lives on! Great work brother!
Thank you brother.
Now that was a great find and great thought process! Good job Corey!
Thanks PJ.
Because of this video I was able to fix the truck in about 45 minutes we soldered the broken weld. Otherwise I would have never figured it out. Thank you so much
Thank you Corey. Good job. Have a blessed and safe week.
Same to you Billy
thanks a lot I finally found the problem in my van
Excellent work Corey!!
Sometime the best thing to do is walk away and comeback to a vehicle later on. I constantly come up with a new test or new idea after I’ve given up for the day or moved on to another vehicle. Thanks for the info on Keith’s series going to check that out now.
Love that A-ha moment. Cheers
Fantastic video!! I had the same issue on a customer's 2016 Express Van.
If there is one thing I learned from smart guys is a successful diagnosis is having a solid and repeatable process. Stick to some basics and reaching out for help and research has become the normal because cars of today are so complicated. Great find Corey!
Thanks Wyatt. Hope that knee is healing
@@SAAutoRepair Very slowly. Months away from working on my projects. :)
I liked it. Quick & dirty.. excellent find! We've all been there, but I like the happenstance of watching Perkins and getting that "aha!" moment. Don't think I've seen vids by you in a little while... so that's also a nice change. 😊🤗
Love that guy. Great attitude and instructor
This is an awesome video! I fixed three fleet trucks today after watching this and after doing all the normal maintenance item, injector, plugs, wires exhaust, and plenum gasket replacements! I did check the fuse but it showed good with test light as looking at it you cant see the fuse was getting hot. Thanks Again!!!
Great to hear!
thank for sharing.those are the job that i like the most at work
Right on. Thanks
Great video man. Fantastic find.
Thanks pal. Sorry I crashed you vid. 😂😂 (No I'm not)
Great job Corey. Thanks for sharing this with us 👍
Thanks for the support
Great job this video saved me alot of headaches. Same exact problem & same codes.
just saved me a ton of time, had the exact issue on a fleet vehicle. thaks.
I have been trying to diagnose why my engine was sputtering. I have a 2013 Chevy Express 4500. I swapped out vacuum tubing. I changed the b2s2 O2 sensor. That took care of a bunch of codes, but I kept getting 0201, 0203, 0205, 0207 and a random other one. Watching the diagram about why all 4 were misfiring made sense. I knew all 4 didn't go bad at the same time. Well, the likely hood of that happening is slim. It had to be happening in the fuse box. I called the local chevy dealer and they had one in stock. Took 5 mins to swap out. So Far, no sputtering. RPMS are sitting strong at 700 at idle. It was jumping all over the place prior to swapping it out.
Your video just gave me the info i needed. Thank you. I found a discolored fuse, possibly getting hot. so replacing the fuse has corrected the misfire and open circuit status, but if it returns, will replace fuse box.
GM's wonderful engineering strikes again! Looks like they designed that one to be nearly impossible to repair, with those sandwiched circuit boards. Great find - thanks for sharing your diagnostic process, Corey!
Impossible? No. But def cost prohibitive. Thanks pal. Hope all is well
Thank you. You saved me a lot of money. That was exactly my problem
Another great one Corey! Thanks for sharing.a
Appreciate you sir
You've been gone so long I almost forgot about you but then I seen you in Joe's video today to remind me. 😁 Glad you're back.
Thanks for sticking around.
I would have never even tried to fix it . I have you on speed dial 🤣🤣
Anytime brother
Well done sir.Thanks for sharing👏
Thank you sir
Good work. Got mine fixed
Good to hear
Nice Catch. Keith is great. I forgot my password to the website. I need to contact him and see if he can reset it for me.
I've been binge watching everything on that sight. Worth every penny
Awesome help!!!!!
Glad it helped!
Very good info thanks man. 👍
You bet
Cory if the customer said give it a try would it be worth trying or just not worth it. Good video and find. First video I’ve seen exposing a problem of that nature in the fuse box. I’ve seen cracked solder joints but not in that location. Good video very clear photos. Hope all is good Artie ❤️
Nah. Time spent trying to repair it vs just buying a new one. And then what happens when it fails in another spot in 2 months? Maybe if it was my own
Like you said not worth the time and effort. Have a good one Cory 👍
welcome back cory!
Good to see you
This video is exactly what my 2016 3500 Express van was doing and you guys save me I have been to two different technicians and they could not figure it out and this was the problem I put a new fuse junction box on it problem solved thank you very much how do I make a donation
Thank you and I'm glad it helped. More importantly, I want people to learn the importance of learning to properly troubleshoot. We're always learning.

My 6.0 had that same intermitant fault.
My first guess was resistance at the injector control plug connection
I pulled the plug put a light coating of lithium grease on both male and female connectors.
Problem solved ✌
good diagnosis... i bet this ended up having a bypass from the fuse that controls the even side to pins g2 n g3 to feed the offside...
New fuse box. Problem with the bypass, is that it will likely come back with a similar issue on another circuit. Hope all is well
Scanner Danner had one just like this
Fighting same issue. 10 2500 with PTO for carpet washer. the pto rubbed against 1 3 5 7 injector wiring and coil 3 wire has break. also few broken wires near pcm and brake fluid been leaking for who know how long onto fuse box..... Customer had injectors replaced. Purchased cats so i installed them (originally why he came to me just to install) now chasing wires FML anyone know of a oem replacement harness and fuse box?
My truck them code po201 po203 po205 po207 pop up that made my engine light come on but they diagnose the truck and them same code not popping up what else could it be can plz somebody tell me🙏🏾👀🧐
do you know if there are any youtubers like you in southeast USA im in alabama looking thinking about getting tnto mobile diag looking to see if anyone is around havent found any
