Electrical problems

Been having an electrical issue come up lately, when I get into choppy bumps the truck will shut off for half a second.. whole dash goes dark and no response from the peddle. Quick look at wires and connectors and everything looks fine except for the one in this picture. I have no idea what this plug is for or if it even relates to my problem. Any help would be appreciated!

 

There's a tsb or recall be for the crank position sensor. The concern is that engine might shut off on its own during operation. I would look into that first if it were me. Good luck! I think the recall applies more to the 2016s but still worth a shot possibly if you can't find anything else.

Could it be a loose battery cable?

 

Have you installed anything involving electrical? Have you checked the fuse, it may be loose or going bad..

 

Wiring that small (as in your picture) would likely blow a fuse before taking out the whole truck. Sounds like something loose or chafing elsewhere.

 

With the engine running tap on the EFI relay with your fingers if the engine stalls replace it.

 

Thanks for the responses! All of these things check out unfortunately.. these all would be easy fixes. I thought it was for sure the battery cable but there good and tight and all my fuses including accessory ones are good to go.

 

I will try this..thanks!

 

Start poking around and give a really thorough inspection. U need to be able to replicate the problem before u can ever hope to fix it. Good luck!

 

Just noticed you're in Chandler. If you need help lemme know. I like fixing shit.

 

Just curious as to if the issue was resolved. I had something similar happen once, was never able to replicate it.
