My car was running and it was missing and it quit and now it will not start. We changed coil ignition last year. We put a new crank sensor on. We have fuel and good air compression. Any suggestions?

Hi Moore,

Are you getting power supply to the ignition coils? Did you replace all the coils? Did you check for trouble codes? Are the crank sensor wires in good condition and is the connector clean and tight?

Yes and we replaced all. We had one that was working prior to the car breaking and we tried it and still no spark. We checked for codes and none. Crank sensor wires are in good shape and they have less than one ohm resistance to ECM.

We fixed the power to the fuses, but car still does not start. We have no injector pulse and no spark.

What was the cause for missing power supply?
This could be a fault with the relays, ignition control or main relay.
Could be some wire connector is loose somewhere or a ground wire is bad if battery voltage is available at coil and no spark.
