[V6-12v] Car not starting

[James Whitehouse]

Yes, the crankshaft position sensor and the hall sensor are one and the same
(it's using a 'hall' type sensor as a crank position sensor). However, it
should throw a fault code for that, so check the fuel pump/relay first, then
consider that after, since you say it's code free at the moment.
