Intermittent crank-no start

[TrumpyAl]

The symptoms match a Crank angle sensor fault. The only way to test would be to use an oscilloscope of some description while the fault is evident.

I’d just go ahead and replace the sensor - even if it turns out to be something else, they are known to fail so a fresh one will benefit you down the line anyway.

I have not had this issue personally. But if I remember correctly from previous posts, if the crank position sensor is bad, the tach won't move while cranking.
