Sometimes I will try to start my Jeep and power will come on but won't start. Then if I get out and rock it forward while in park it will start. Have no idea why? Is something not engaged in the transmission or drive train? Dumbfounded.
Do a search for clutch override fuse. It might even be in your owners manual. As I remember, on my 2001........You have to add a fuse to the fuse panel behind the glove box. It disables the clutch interlock switch safety feature.
