Title: Crankshaft/camshaft position sensor works, no spark
Post by: PaulsM 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.

you should check ignition driver inside the ecm at test debug mode.

How do you know if there is and there is no supply on coils?

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