Yes I am getting power to the coil and I do not have a remoter start button...I get one spark upon turning it over...every time I turn the key on and try to start I get a single spark but no more until I turn it back off and try to start again
Try bypassing everything between the ignition switch and the solenoid and jump it for a second at that location. See if it wants to turn over from that spot. If not, it's not in the switch.
Do lights, radio, etc. work when the switch is off? Check for a corroded ground wire from the battery.
Check the ground wire from the throttle body to the firewall. If it gets real hot you could a loose connection at coil .
i let run for a few min and cut off and want restart have fire and smell fuel
It will crank but won't fire
