Wayne 0 Report post Posted July 31, 2021 I have a M50 it’s in an E30 . It’s was running a bit rough and now not at all. it has spark and full, I found out the cam Sensor wasn’t even plugged in and there is no visible plug for it. I can recall this lose plug when I bought the car so apparently it’s been running without a cam sensor, is this possible? and what’s up with my car ? I’m leaning towards crank sensor. Any advice would be much appreciated cheers Wayne Quote Share this post Link to post Share on other sites
NZ00Z3 187 Report post Posted August 1, 2021 When you crank the engine, does the Tacho jump up a bit? If it does then your crank sensor is working. If the Tacho is flat lined, then look at the crank sensor. Quote Share this post Link to post Share on other sites
