Crankshaft/camshaft position sensor works, no spark
« on: May 14, 2017, 04:42:42 pm »

Hello. Why would VEMS turn off spark and maybe fuel injectors, at triggerlog record I can see crankshaft and camshaft sensor.
Drove home, everything fine, next morning car won`t start. Then, after a day it starts, then again nothing, but both triggers work.

When the car is ON there should be one wire that has 12V
