I have a 89 mustang with a 5.0. motor, the problem i am having, is i can push start the car and it runs fine, but as soon as i shut it down it will not start up, i can hear the starter solenoid, the horn and lights work, when i turn the key on the fuel pump engages, i engage the clutch and all that i get is the sound of the starter solenoid. The starter will not engage none what so ever. Also there is a lot of heat under the engine bay
