Default Starts after 3rd try...

My 2012 Dodge Durango had the TIPM replaced, then the fuel pump relay installed a couple of years ago.
Now at 88,000 miles the engine cranks but doesn't start. It takes three trys.
Anyone had this problem? Is it the relay? Or the fuel pump?

Thanks

Claus

Kinda sounds like fuel pump and or regulator have you checked fuel pressure with a gauge ? Hook up pressure gauge turn key to run but do not start pressure from pump should be around 50 to 60 turn off key and it should stay if it drops rapidly back to zero then pressure regulator is bad time for new fuel pump

I've already had to replace the replay for the fuel pump on my 13 R/T... And I'm beginning to wonder if it's going out again as we have occasional rough or longer starts... Sad these relays don't last longer, but it's an easy fix and was only $12 (when I purchased it last time).

Hopefully that's all you have going on!

Default Recall 09

I got the fuel pump relay recall done @72,000 miles on December 2015.

The relay failed at 88,000 miles on February 2017.

Good thing: easy and inexpensive to replace.

Bad thing: car can leave you stranded.

Is this the MOPAR replacement weatherpak relay or just a traditional plastic encapsulated relay?

I performed the TIPM procedure myself and the relay seemed pretty well produced. It seems odd that the same behavior that killed the internal relay has killed your external one.

I may pick up a replacement to keep in my glovebox 'just in case'. Since it is an easy PnP swap.

Default It was installed by the dealer

This is the relay before I took it apart.

When I started having issues, I replaced the dealer installed relay (I assume MOPAR approved/recommended) with a standard autozone 40A relay to test. Same pinout/plug. Worked great. I then ordered a direct replacement (ebay link)... However, as I've already had one or two difficult starts recently, I'm going to order another one, as you said, to keep in the glove box. I thought about using the higher current replacement from Autozone, but it's not sealed for waterproofing... I may see if I can find a higher current version of this relay. It's 20A and maybe that's not enough for long term use... *shrug*

Thanks; that's the one I expected to see. I'll definitely order one and keep it in the vehicle.

I wonder if the location under the hood, exposed to temperature extremes is causing premature degradation.

The high current contact shows signs of significant arcing, like it isn't closing fast enough.

Having the same issues. 13 RT with 62,xxx miles. Recall done around 50k or so. Dealership should cover this ****. It's aggravating.

Mine is still under an MVP plan. I'm not gonna pay for this fix. I refuse.
