2004 S80 2.9 non-turbo: Starting issues

Post by dejongmc »


Recently I had to move my car about 6ft to make space for one of our other cars and ever since I'm not able to start it anymore.
So far I did the following trouble shooting:
- The starter does work, but the engine doesn't crank
- Checked the battery if it holds a charge > ok
- Before I took the battery out to test it, I was able to read the following codes: P0420, P0430, P0455. But even with these codes I think the car should still be able to start.

For a while I know that my ABS module needs to be replaced, but I do not think it has anything to do with this issue.
Next thing I want to check is the fuel system, but I'm not sure how to trouble shoot that.

So I'm asking for any other trouble shooting steps to narrow down this issue.

Crankshaft position sensor most likely. Did it also shut down without any warning? If yes, than most likely that sensor.

How long did it run when you moved it, and did this start just after moving it? This sounds like classic symptoms of lawnmower syndrome. See here... viewtopic.php?t=18175

Those codes won't prevent the car from running, they're for cat efficiency and an evap leak. When you said the starter works, you mean that the engine is actually cranking over, just not starting, correct?
