A Nissan Murano 2004 V6 has a bank 1 Ignition problem. There seems to be no spark from all 3 cylinders in bank 1. Swapped all ignition coils to those in bank 2 and vice versa but still no spark and they would work well in all 3 cylinders in bank 2. Tested for battery voltage on all 3 cylinder coil connectors in bank 1 and there seems to be battery voltage. Replaced bank 1 camshaft position sensor problem still persist. What could be the problem?? Could it be bad or shorted ground?or bad ignition ecm wiring to bank 1 or bad ignition condenser

I believe for some reason that we should have a constant gnd on one of the terminals and a 5V refrence or 4.5V if it is a three wire coil,we should have battery voltage,5V, feed back i.e IGF some are grounded on the coil pack their self and one more thing the five volts only appear on KOEF i.e key on engine off.

Run a scan

Run a scan

ran a scan already sir. got p0300, p0301, p0303, p0305 and p1136 (intake valve timing control solenoid valve bank 2)

Have the intake valve control solenoid changed. Before that check for corrosion, excessive oil contact, check for B+ voltage, test solenoid to see its performance. If you have a professional scan tool, activate the solenoid to confirm if it works. Good luck
