Question

I have No spark at #2 and #5 plug wires. I have anew ECM and newer coil and OBD code P0352. What can I do to find out why I have no spark at #2 and #5?

Answer 1

P0352 Ignition coil # 2 primary circuit

The primary circuit #2 is for the ignition coil driver circuit. This circuit signals coil pack secondary for cylinder 2 and cylinder 5. You have a break at either the ECM and this inculdes the ECM even if it is new. and the harness from the ECM to the ignition coil.Check the ECM for pins that may have been pushed in. If the wire from the ECM coil driver primary # 2 and you meause the appropriate voltage which is above 10 votls and the coil pack primary resistance is below 2 ohms. This can be a faulty ECM
