My car is a 2005 Expedition.When I go to turn the truck on, it's a loss of power. The truck will not start. It was suggested that the GPS system could be the problem. It sounds like the battery is dead, but it's ok. Makes a noise from the starter, but it's fine. The red light from the alarm is blinking normally. This is the third time this has happened. Yesterday, I unplugged the battery for a while and when I plugged it back in and none of this happened. I got a jump start and it worked fine. This morning when I tried to start it, the same problem reoccurred. I couldn't start the truck. When the beeping noise comes on, the truck won't start. Do you think it might be the GPS system. I bought the truck 2 months ago. I only have one transponder key. Any suggestions? Is the GPS tracker causing this? or the PATS system? Should I disable the GPS tracker. Let me know if you have any ideas or suggestions
