Jeep Cranks But Won't Start. PCM Bypass Solution.

The Jeep turns over but will not start and won't stay running. There are other videos on youtube about diagnosing this problem but I did not find one showing you how to fix it without replacing the PCM (ECM, ECU, Computer, or whatever else you want to call it). This part is expensive for OEM and requires a dealer to flash it, or program it before install. Ouch, that's a lot of money. The fuel pump relay is not serviceable on a Chrysler, Jeep, or Dodge product. Here is a way to get your vehicle running for about $10 and not have to worry about buying an expensive part and then paying to flash it.

WOW! You just saved my 2008 Jeep Patriot from the graveyard. I was minutes away from handing over my title to the Jeep dealer, who said the PCM is bad and they cant fix it. They contacted a junk yard who was going to give me $250 for it. I was reeling because otherwise it is a nice car with only 90, 000 miles. I thought I would give this a shot first and woohoo, started right up! My fuse box is different than this one shown on the video, however. We'll see if this lasts and if other issues show up, but right now everything looks good, but now my engine light is on. Oh well. I have a running car. A million thanks!

Although that’s not the problem I have, I think you bypass idea is great and I appreciate the detail you went to to verify. Awesome work buddy!

Well you are talking about and fixing an issue with the TIPM (Total Integrated Power Module) PCM - is a different thing - (Power Control Module) ....it is the silver flat box in front of the "fuse Box" - TIPM one with 3 big plugs with gazilion wires in each of them . but apart from calling it the wrong name glad it worked for you

[ElizzaBeast]

Omg thank you so much…. I got a multipack of the fuse taps from Amazon for $7 and was able to get my Jeep to start… you definitely saved my butt

PCM – POWERTRAIN CONTROL MODULE
TIPM - Totally Integrated Power Module (Fuse Box)
ECM – ENGINE CONTROL MODULE
TCM – TRANSMISSION CONTROL MODULE

This video literally saved me from having to spend hundred of dollars on a simple problem 👍🏽👍🏽👍🏽🙏🏼🙏🏼🙏🏼 AND IT WORKED I have a Jeep Patriot

Wow awesome i actually just looked at your site from a vid on Lack Luster and you have just helped me solve the problem with my Wrangler! Thanks for 2 lessons in one day my man, even if it is 2 years later!

The relay is on the inside of that control module on the bottom side. It’s soldered in you can’t see it. You have to take the control module out and take the entire thing apart in four different pieces to get to the relay solder it out soldering a new one. There was a video I found on YouTube on how to take it apart.

Fantastic FYI everyone it worked for me on a 2007 Jeep Wrangler. Hell this advice is worth some beer money or dinner or something to you sir.

Thank you so much for this video! Dealer wanted to charge me $1600 for a WCM replacement!

[akandwanahoraymond]

Thank you for that wonderful advice. Mine is a commander 2007 3.0 CRD, crank but no start, DTC P0607 that is turning off most sensors needed to start the car. I just took turbo off and put it back after overhaul kit. Any ideas? I wonder if some ground is not coonected or there is a short circuit. Fuses all look fine from inspection

[blkrvrbart]

So this is a permanent fix until a fuse blows? That’s incredible. Thank you!

[hardyoakmaintenance]

Would that be the same for a push button ignition

[perryjones]

Thank you so much . Perfect video & well done. My 2013 is back on the road😊

My 2011 Jeep Overland started having this issue today, that is what brought me here. Looking at Mopar's website it appears they issued a recall notice in 2019 for this known issue.

[miketran]

Thank you so much. Perfect video & well done.

Would the pump run if the keys are in Acc position??

[walidshibani]

hello mr..i did it before...but its better to join a relay 30amp by connecting a real circuit with the dark blue orange wire below the box under the m25 fuse anyway i like the piece you used its a simple way at least to move the car

I’m gonna read every comment this is amazing. I have a 2011 Liberty. I need a voltage tester ASAP
