Sometime problem with ford explorer starting Sign In

We have a 2011 Ford Explorer, 6 cyc. About a month ago, when turning the key, it does not start - but all the lights, radio, everything else works. Turning the key on and off, opening and closing a door, will eventually start the vehicle. This is starting to happen every 3 or 4 times starting it. We have had the battery tested - and is good. We had the Ford into the dealer we got it from (not a ford dealer), and they just looked at us like we were nuts. Hopefully, after Thanksgiving we can get it into a Ford dealership, but would like some idea of what is happening before then. The nearest Ford dealer is not a favorite of mine. Thank you for any feedback.

Any technician is going to have to be able to duplicate the problem before he can do any testing and without a failure and tests during the failure, there is no way to diagnose this.

There is a TSB concerning connections at various electrical plugs.

Electrical - Joint Connector Information General Service Bulletin (GSB):
Joint Connector GSB

GSB Overview:
This GSB covers what vehicle lines use Joint Connectors, what they are
and where to find information about them in the Wiring Diagram (WD)

This information is not intended to replace or supersede any warranty, parts and service policy, Work Shop Manual (WSM) procedures or technical training or wiring diagram information.

This information is not intended to replace technical training,
Workshop Manual (WSM) or Wiring Diagram information or procedures.


This GSB applies to specific Joint Connectors used in 2010-2015 Taurus, 2011-2015 Explorer, and 2014-2015 MKS vehicles.

What are Joint Connectors and why are they used?:

^ Provide a connection point for two or more wires within the wiring harness

^ Aid in wiring harness assembly

Joint Connectors within the wiring harness:

Joint Connectors outside the wiring harness:

Joint Connectors in the PTS online Wiring Diagrams:

Joint Connectors in the PTS online Wiring Diagrams:

The Connector View for the Splice Blocks is located in Cell 150-1 of the Wiring Diagrams.

What type of concerns can result from a poor connection within a Joint Connector?

^ Pin pushouts, loose terminals, poor terminal crimps, wire damage, etc. can result in an open, shorted or grounded circuit, which can cause various issues and may be intermittent.

How are the circuits within a Joint Connectors tested?

^ Power, ground, and continuity checks for specific circuits that may contain a Joint Connector are listed in an applicable Workshop Manual Pinpoint Test.

How are the circuits and terminals with a Joint Connectors repaired?

^ Depending on the severity of the concern, affected circuits can be removed from the connector and spliced together, as necessary. The connector can be bypassed for one or all circuits. Use splice kits 3U2Z-14A088-AB/BA/CA to make waterproof repairs. Follow the instruction sheet in the splice kit.

How is the cap released from the Joint Connector?

The Cap is released from the Joint Connector using a tool to push the lock toward the connector as shown.

Differences in Joint Connectors:

Joint Connectors can be different. The brown connector on the left has the upper and lower six pins joined into one circuit on each row. The white connector has only three pins joined into one circuit on both the upper and lower row. In some cases, these 3-pin connectors may be connected together via a wire loop as shown in the picture and schematic.
