    If I'm following you, you need to remove the fuse to check  and you need a multi meter, set on ohms, and touch each end of the multi meter to the fuse.

    A test light checks for voltage. You need a volt-ohm-multimeter set to continuity or ohms (resistance).

    Power supply unit could be bad.

    If you turn the key to the ON position and the CEL lights up as it should your computer is getting power. I don't have a clue why you're thinking it doesn't have power. Did you check all the sensors for the 5 volt reference signal? If you don't have 5 volts at each sensor you need to unplug each one to see which sensor is shorting out the 5 volt reference signal. One bad sensor shorting to ground will take down all the reference signals and keep the motor from running.
