Jerking issue C14NZ engine

[DavebGsi]

Without the crank sensor you will definatly have no fuel as the engine doesn't know when to inject the fuel, so it doesn't even try basically. Their cheap enough and easy to fit yourself I would imagine

The mechanic told me the engine did not have a spark, is the no spark issue related with the no fuel from the injector?
He ordered a new ignition unit with the hall sensor in it (not sure how to call it).
Makes sense... It could have something to do with the stuttering. Hoping it's solved with changing the unit...
