My Fastrack spuratically will not start. Turn the key and the motor spins but will not start. Everytime I load it up to take to the dealer, it starts. Dealer said it's probably a switch but I have tested and bypassed both steering and the seat switches one by one and all together and even with all the switches bypassed it won't start. Went through this whole process yesterday, no start. This morning went to load it up to take to the dealer and it started. Anyone got any suggestions on what else to check or replace?
