Did you check for any malfunction codes .

Have you checked and tested the cam / crank sensors .


Customer: replied 1 year ago.
I didnt do any code checks. But it seems like an electrical issue. Maybe but i dont know about coil pack symptoms. No check engine lights are on.
Expert:  Greg replied 1 year ago.

If the engine shuts off and then no start and the coil is good then check the TDC sensor and crank shaft sensors,

Most common for this issue like you are having is the crank sensor .
