CEL indicate problem with engine emission and to my knowledge can be only set when the engine is running.
If your engine will not start, this is mostly due the fuel delivery problem, or bad CPS.
None of those triggers a code, than not having a scanner you are not sure.
Since the scanners are way cheaper than dealer's charge for one tome scanning, this is no brainer to me if i should own one.
