If you have the m20, did you mess with the timing belt at all? Check the timing and reset it if it's off.
And as for the crank position sensor, did that get tweeked at all?
How can I tell if it is a m50 or m20 engine? And also where is the crank position sensor situated? I dont think I messed with the timing belt unless it is the bigger belt of the 2..... Thanks for youe help
