Hi there,
called out to a garage with a golf non start. Second hand engine fitted, crank sensor replaced vehicle on test drive lost power. Got it back to work shop and stopped it, it would not restart. I tested it with scope and crank sensor was sporadic with signal. Fitted new one, that is this engines fourth and it ran perfectly.
What could cause an engine to go through so many crank sensors??
I replaced coil although I thought if this was spiking it would damage ECU not sensor.
The sensor is a hall sensor and this vehicle has also had a new dizzy fitted by garage before I got there.
TIA
James
