    that just happened to me about a month ago at most but i changed the main relay and it wasnt the problem then i changed my ignitor and that was it but to check the ignitor
    1. remove distributor cap and the icm cover
    2. disconnect the wires from the icm unit
    3. with the ignition key turned on check for voltage between the black/yellow wire (middle terminal of the ICM unit) and body ground. there should be a battery voltage
    4. if there is no voltage check the circuit between the black/yellow wire and the ignition switch
    5. with the ignition key turned on check for voltage between the white/blue wire and the body ground. there should be battery voltage
    6. if there is no voltage check the circuit between the corresponding wire and the ignition coil
    7. check the continuity between the white/blue wire and the blue wire of the ICM. there should be 1.1 to 3.3 k-ohms
    8. if the ICM fails either of the above checks replace it
