Bad Connectors - No Power to Fuel Pump

Mostly Affects 2014+ Dodge Durangos and Jeep Grand Cherokees

Sent to us by valued customers:

I had an intermittent crank/no start, crank/die issue on my 2016 Durango. Bypassing the fuel relay didn't result in a start indicating a bad fuel pump. I replaced the fuel pump. Still the same issue. I next replaced the TIPM, still the same issue. After hours of research on the Durango forums I found some people that were struggling with the same intermittent issue that may help your customers in the future. I would like to help get the word out because dealers/mechanics are not catching this and it's costing people a lot of time and money. One poor dude spent almost $5000 on multiple parts replacements, diagnostics and tow trips to the dealership.

It looks like 2014+ model year Durangos and Jeep Grand Cherokees have an issue with melted wires/terminals near the fuel tank jumper wiring harness, similar to the known issue with Chargers/Challengers (only they present directly at the fuel pump connection). It initially presents as an intermittent crank/no start or crank/die issue. Bypassing the fuel relay with your bypass cable indicates a bad fuel pump but in reality it could be this burnt/melted wire/terminal. Before they spend the time/money on a new fuel pump this connection should be checked. It's easily accessible and saves a lot of time and money from dropping the fuel tank to replace the fuel pump.

Scott Wooster shared this image of a similar failed connector at the rear of the fuel tank (noticed the one overheated/melted pin).  He bypassed it by soldering a red 14 AWG wire to avoid the bad connector.

On a 2012 Chrysler Town & Country, John mentioned: "At the connector behind the tank I found the problem (or at least this one)...that position got hot enough to melt the connector. I bypassed with a locking weatherproof rated at 60A. Works until the next thing!"..
