93 subaru impreza turbo

[bazil]

my subaru it turning over and going to fire up but wont start any ideas what
it could be i have been told it might be the crank shaft sensor? also i was
told it could be that it needs a service? but has anyone else got any ideas
what it could be before i start spending money on something that it might not
be.

Start by verifying the engine has spark. No spark then the CAS sounds like
a good possibility.
