It also shows a code for the crankshaft position sensor. I've changed the spark plugs and checked the fuel injectors and still nothing. Any idea which direction to go?

Hi,

There could be an issue with the crankshaft position sensor. If I recall, you have three coils on this, correct? If so, each coil is having an issue. All three wouldn't have failed at the same time. (See pic below)

If you want to check coils, pics 2 and 3 explain how to do it.

If you are comfortable performing the test below, let me know. Also, let me know what specific codes you are getting.

Take care,

Joe
