The other day I accidentally locked my keys in the truck with the motor running. The hood was open because I had been jump starting someone, so I just pulled the relay to the EFI so I could cut the engine. About an hour later I took the negative lead off the battery so that it wouldn't be sitting with the ignition on. I couldn't come back with the spare key until 2 days later. When I opened the truck and reconnected the battery, but it wouldn't start. I thought maybe the battery was dead so I tried to jump start it and I got nothing. The starter didn't even give the smallest click. The connections are good, the battery has a charge, and the EFI Relay has been put back in its place. Does anyone have any ideas?
