Hi my name is John.
When it won't start do you have power to the coil?
Does the other side of the coil flash as your turning over the engine?
I would test the power and ground for high resistance with a ohm meter to the ignition switch and the headlight switch.Have the battery disconnected when test for resistance.
let me know if you need more.
please push the accept button when were done.
Thank you for choosing just answer.
i test wires J1 red wire at the ignition for power and wires J10 pink ,J2 dark blue for power 12 volts
I test the ignition switch first.
The ignition coil is powered by the ASD relay and controlled by the engine controller. The ASD relay sends voltage to the positive side of the coil, and the engine controller is connected to and controls the negative side. The engine controller applies and removes the ground from the coil according to signals it receives from various sensor inputs. When the engine controller applies the ground to the coil, secondary voltage is discharged to the spark plugs via the distributor . When the ground is removed from the coil circuit, secondary voltage is not allowed to flow to the spark plugs until the engine controller re-applies the ground
yes ask the question
