Any advice on a code scanner?

8. Parts store guy free scan data worth what you pay.

Forget the cheap ones, you might as well toss you wallet in the harbor.....
In addition, ANY scan may be futile because it's a "no start" condition and the resident codes may or may not have any bearing on why it's not starting.
Most no start complaints are fuel pressure or lack of spark related (unless the dreaded timing belt snapped) so there may or may not be a valid code in memory anyway.
When you cycle the key the ECU powers the fuel pump for 2 seconds and refers to a read only map to control spark and fuel injection just long enough to get it to run, then after it (the ECU) sees crankshaft rotation (above starter motor speeds) it begins to monitor sensor inputs and manages output commands to the injectors and ignition system SO, no codes can/will set during "key on/engine crank" situations..

Did you have a "Check Engine" lamp lit the last time you drove it?
If so there will be a fault code (or 9) in the memory but the stuff that sets a fault codes are not usually responsible for no start conditions. (Hard start maybe).

To sum up, be wary of non-professional scan related info, changing parts until one of them fixes it can get real spendy real fast.
