2006 XC70 Hot starting issues Topic is solved

[Rvolvos]

Which cylinder is dead? Move coil pack from a working cylinder and see if the misfire moves. I consider coil packs a 100k maintenance item, although many will run 'til failure.

Spot on, I guess I did too. But I did swap the coils from our V70 with @153k. I put back the original coils in cilinder 1 and 5 and it starts and runs fine

So how about that? Your Volvo isn't dead after all. Just nicely broken in at that mileage.

Does anyone know what the values for the Front and Rear oxygen sensors should be?
Attached a picture of the values when idling. Long term fuel levels look good, to my knowledge they should be around 1.

Considering this topic solved. I have put in new coils from FCP Euro and the car starts fine cold and warm.

After the timing belt and vvt hubs installation I scanned the car for codes to make sure if no errors where introduced.

I did replace the starter with a lower mileage one ( had to remove the starter anyway for the vvt hub replacement) and prior to the the antenna ring.

The following codes popped up for the first time.
ECM-291D fuel pump control module- signal to low ( Pem has been swapped with one from a 2011 c30 (124k))
CEM-3F90 fuel pump, relay open circuit or shorted to ground
Multiple instances where recorded, but not much detail information other than to check the wire harness.
Any one got these codes too?

Please ignore the post above. DTC must come from fuse removal from fuel pump and cranking the engine.

Happy to report that the car starts consistently with the newer starter.

if only it was always this simple.
