Good info. My 2011 JGC Limited Hemi (98K miles) just gave me the no start for the second time in about 10 days now. It had been sitting in my garage for 2 days and I did verify that the fuel pump relay replacement with an external relay was completed about 3 years & 40K miles ago. I'm headed out on a 2500 mile trip starting this coming weekend so I ordered one of these Omron relays from Amazon and will have it on thursday. At least I'll have a relay with me to hopefully correct any non starting issues I encounter.

So you are all talking about the "no-Starting" problem which i've had to deal with as well. Dealership fixed it for though, twice now..

However, i don't see y'all talking about the "shutting down" issue... and it only happened as i applied the brakes to start slowing down.. That's been the worst of the issues. just driving a long, slow down for a turn, and BAM, jeeps shuts off on me. i started using my key fob so i could just put it in Neutral and restart quickly so i don't slow traffic down much.

i actually don't use the push to start function anymore, seems to shut down more often when i do. haven't had any issues since using the key fob.

Here is my recent experience with a 2011 WK2 with hemi V8. Intermittently, the engine would crank but not start. Then occasionally it would crank with significant misfire and raw gas smell. I dropped it at the dealership. The tech verified the crank with no start condition and found there was no pressure at the fuel rail. Tech concluded that the external fuel pump relay installed under the 2014 recall had failed. Defective external relay was replaced at no cost under the recall program. I pickup the vehicle today and hope for no repeat of the problem. It is difficult to understand why a fuel pump relay would only last less than 4 years.

My 2011 had started to occasionally be hard to start over the past few months. Long cranks finally starting after 4-5 attempts. Last month it stalled on me on a parking lot and it took about a dozen tries to start it. My JGC had the fuel pump relay recall completed about 40K miles, 3 years ago.

So I bought a $12 Omron relay on Amazon, took 2 minutes replacing it, and all seems fine now. Who knows, could do it again but relays do actually wear out over time since they're a mechanical device subject to extreme conditions in the engine compartment.

You'd think redesigning the TIPM to fit ONE MORE RELAY ON TOP with the rest as easy access required redesigning the whole fleet.... Pretty sure I've just run into this issue. Driving and suddenly the engine dies and acts like I'm out of gas (when I just filled up the 3 quarters of a tank so lol) Whoever designed this thing, as well as all the approvers down the line seriously need to suffer a piston through the cabin for this nonsense!

^ This!

To all those savvy under the hood that will be your best bet, as well as some of the aftermarket harnesses. As of now (June 2019) the two places I've hit up for the official harness will only ship it to a dealer to my dismay >:{

Also keep in mind.... the layout of you fuse box may be different from many of the videos on the issue, depending on your vehicle and year. I've figured mine out but be advised. May upload a crappy video of my '14 just for reference lol

2011 Grand Cherokee 3.0 CDI (registered to post here for your benefit)

I can confirm that the "Fuel Pump Relay Recall Fix" is the issue on our GC - we had the recall done as a preventative measure, and surprise surprise, our failure was the actual "recall" relay rather than the factory fitted relay.

Symptoms, regularity & history:
  1. 12-24 months: Stall straight after start, rare initially, increasing to 2-3 times per week
  2. ~3 months: Long crank without starting, 2-3 times per week initially, increasing to 2-3 times every day
  3. ~2 weeks: Engine cuts out while driving, has happened twice
FYI: If you have had the recall applied to your jeep and suffer the same symptoms, I found there is another relay mounted closer to the firewall that is compatible with the Recall Relay (at least my car has it), and you can simply swap these over to get you going again. It's attached to the Bosch relay block adjacent to the strut mount.

Thoughts: this is an appalling situation and solution from FCA, no more than a band-aid patch up job that risks stranding vehicles and occupants in life threatening situations.

Ok so I am dealing with this issue now. My GC had the recall done before I took ownership and this year it starting cranking for along time. Sometimes it wouldn't start, sometimes it does. Replaced relay with exact relay it has, still the same problem. Found another relay on a jeep website and got it from AutoZone and still the same issue. Not sure what to do now as it does it with any relay. Is this an actual fuel pump problem or something else?

Hi, by installing the new relay was your problem fixed? regards.

Hello,

I have been dealing with continuous cranks but never turns over for probably over 8 months. Occasionally it does start and then rumbles off. This behavior is not always consistent. It can go weeks with no issue.. then some days it never wants to start. So far I have not had it shut off while driving. I bought my 2012 wk2 in 2014 from a caddy dealer. This recall, the current and the previous never came up. So I'm unsure if it was fixed the first go round. However, now fiat is claiming they don't have parts to fix it. Today alone I lost a half hour's worth of work time. Wouldn't start in the AM and made me late.. then stranded me on my lunch break, thus making me late again. Husband is currently driving it and stopped at the grocery store and left it running for fear of being stranded!
I've read all these posts and thank you all for putting the info out there. If I hadn't come here and went solely off the dealer, i'd be without an option since they wont even replace a possibly already replaced shitty relay.
I think I am going to take my chances and attempt putting in the external relay myself. I'd rather drive around with a couple extra on hand than get stuck every time I go out.

Thank you to whomever posted the link for the replacement part!! I'm going to yell at the Jeep dealer one more time and then I will order said part. I'll post the outcome!!! if I remember!

Re: Another TIPM Problem WK2 Fuel pump relay UPDATE



Thanks for posting the specs!

Based upon those numbers... the non-FR version is a higher quality relay probably made for heavy duty application.

It can handle significantly more current... and is much more energy efficient.

Chrysler probably didn't consider it because it's $2 more in bulk... and that adds up to millions over the course of a recall. The cheaper FR version probably met their requirements anyway.

This relay might just be a REALLY GOOD thing! I have absolutely no issues with the specs.

It seems to be working great for me. Perfect starts all day long today. Definitely beats going to the dealer which I originally had planned for today.
The relay installed when recalled a few years ago is G8JN-1C6T-F-R-DC12.
My Grand Cherokee has been delayed in starting these days, so I replaced it with G8JN-1C6T-F-DC12. The engine starts easily now.
I wonder if product number without R is better.
What is the difference between the two relays?
G8JN-1C6T-F-DC12
G8JN-1C6T-F-R-DC12

I wonder if product number without R is better. Which is good for fuel pump operation?

I am in the exact same situation with my JGC 2013, it stop suddenly and impossible to start. So I took it to a Chrysler dealer, and after all the advices I gave them regarding the new recall etc.. and telling them it was certainly a problem link to the recall, they gave me the diagnostic that it was my fuel pump which need to be change... more than $US900. So I went to buy a new relay to change it with the old recall, and did not solve the problem :(

in my case NO :( I have try 2 different brand new relays, but I must say that the battery was getting very low (because of the dealer may tries before grrrr.) He told me that the fuel pump has to be replace... xxxx$

That is what my Jeep dealer told me. Did you change your fuel pump yet ? Has it been fixed ? Thanks

I am in the exact situation, were the dealer even refuse to change the <existing recall relay> because of a <safety argument>, so I bought one and did it myself today, but it did not solve the start problem :(
so I have to go with his diagnostic, that I have to change the fuel pump :( xxxx$
What happen in your case ? How did you solve your issue ? Thanks
