In cold weather now it takes about 10 to 15 seconds when I turn the ignition
key to ON for the instrument panel gauge lights to all light up. Once this
happens then I can turn the key to START and the engine starts fine. If I
just turn the key to START on a cold morning then the engine will crank for
10 to 15 seconds till all the instrument panel gauges light up and then the
engine starts immediately. Does anyone know what is causing this slow start
up with power I assume to the electrical system(relay?).

Thanks, Tom

Check and clean the terminal connections at the battery. Check that the
ground wire to the motor from the battery is still intact where it
connects to the motor on the power steering pump bracket. Next
investigate the ignition switch for power and continuity. Then the
ground circuit for the instrument cluster. I believe the ground wire
runs from the cluster through the harness to the ground bus on the
bottom side of the central electrical unit.
