i have a 01 f-150 manual trans 4.2L, last week driving to work the radio and wipers stopped working, they would turn back on everytime i pushed in the clutch. the other day i went out to start it and everything worked, the truck turned over strong, but would not start. it sat overnight and started right up in the morning. i sprayed the petal position switch with contact cleaner and it seemed to help with the radio and wipers, however today i went to leave the work site and once again it would not start. i just put a brand new battery in it, and today in 4 hours with nothing on it drained it down to 6 volts. i disconnected the terminals and the battery went up to 11 volts. i took the battery out and charged it to 13 volts, 2 hours out of the truck and reinstalled it. no draw. turned over strong, but would not start. please help any ideas would be greatly apprectiated.
