Default fuel pump runs on it own

Our 07 Mark LT had not been driven or started in a weeks time, we had been using the Town Car instead. I walked out to the garage and the fuel pump in the LT was running. No keys in the ignition, it kicked in and started running on it's own completely. Is it the control module above the spare tire?

Does it have an Air suspension? it could have been the compressor turning on.

Check your battery. When i left my lights on and drained the battery the solenoid for the alarm which is located behind the back seats was clicking. I thought it was my fuel pump but was the alarm. If you put your foot on the brake it should stop. If it does then that is the issue. Have your battery checked and charged if needed. There is a post on here somewhere about it. Don't have the time to look though.

Hope that is the only problem. Free to fix!!!!!!!
