OK. Basically. to get the truck to respond. You have to have it in neutral then turn on the key. put it in forward or reverse. It basically jumps then dies. If you try to creep it you can hear the motor try to move but it does nothing until it jumps and dies. If you jack up the front tires with no load and slowly push the pedal it starts to spin and low and high kick in fine. Sometimes it stops working this way and you have to reset it. SCR2 tested bad on his handyman tester. It shows open.
