I have finally got the new (used) VK45DE from a 2003 Q45 installed into my 2002 Q45. Last night, as the self-help garage was shutting down, we tried to start the car. It turns over, but it didn't run. There were a few backfires.
Question: Do the wiring harness connectors have identifying numbers on them?
I have 2 connectors that are not hooked up.
The first one is the light blue connector at the back of the engine, that should be the Coolant Temp Sensor. It looks like the '02 and '03 years differ here a bit. It seems there is like an inch or two needed in order to connect this connector.
The second one, is hanging down in the back of the engine, and it looks like a wide white connector, with 8 pins in it. I'm really curious as to what this one could be/go to. I'm home now, and will be heading back to the self-help shortly.
Question: The coil pack tube... should it be able to rotate freely from the coil square at the top of it?
I need to get this ride running!
All the best,
