So today I'm driving to work and all of a sudden I feel a huge power loss. Stepping on gas but car is not moving. Finally just stalls.

Tried restarting but would not start. Let it sit for a bit and finally starts up again and was able to get into my work parking lot which was literally 100ft from where I was stuck.

Check the codes and had these two:
U0109 - Lost Communications to Fuel Pump Control Module
P015A - Fuel Pump Module Control Circuit/Open

So I've read all the other posts on these codes and checked the fuel pump fuse and it appeared OK. Only other issue I would think is the Fuel Pump Control Module itself or the connection going to it.

Can someone tell me where this module is located?

Car is a 2016 HC with less than 5K miles.

Thanks,

Lou

Did you find the core of the problem? Having same issue rt now. Thanks.
So I had to assume it was the fuel pump module relay as since I did that, I have not had the problem since. Easy and cheap to do.
Thanks for the info/update. I really appreciate it. Gonna look at the car tonight. I'll report back when I have an update.

Good thing I was taught to check for the easiest possible problem first. Was simply the fuel pump 30Amp fuse was bad. Thank you for your help. I appreciate it.

I would take it one step further and attempt to determine what caused the fuse to go bad usually there is a reason fuses blow.
That was my first thought when I saw the fuse. I definitely need to look into the cause of it for sure. Will keep updating if I find anything so other members can learn or troubleshoot if the same happens to them.
