Hey there,

Anyone want to way in on this puzzle... I've been at it for days and am beat.

My Titan Cranks but won't fire.

No spark at the plugs or triggering pulse, but the coils have + 12v and good ground.

No fault codes.

The immobiliser /security light on the dash is going out when I put the key in the ignition.

I've tried swapping fuses and put in a different IPDM

Crank sensor is showing 200rpm via ODB2

Tried a new cam sensor. No dice.

Visually confirmed Crank shaft is rotating.

Thanks for any thoughts.

Henry.

Unfortunately I see you received no reply, I’m curious to know what was wrong.

Hey, Clint. I'm having the same issue you had, with my '05 titan. I've checked ohms on my crank/cam position sensors, confirmed voltage to MAF sensor, the truck cranks over but no/low spark getting to plugs (used a spark tester). No codes present from OBD2 but now I'm getting connection issues with it. Sometimes it says it's unable to connect to ECU. I don't want to fire the parts cannon at it, just want to repair what needs fixin'. Does anyone know how to test the ECU? Did you get your Titan running again? What was the issue? Thanks
