Trouble with starter

Safety Neutral switch?Try grounding it.

I would guess so. Look up your starter relay on the firewall, since your's was an auto, it should have two "push on" terminals. One should be a yellow/ combo color, and with a test lamp, should be "hot" when the key is twisted to "start."

The second terminal must be grounded to actuate the relay. On vehicles equipped with a clutch safety switch, this second terminal was routed through a separate little grommet in the firewall and to the switch on the clutch pedal.
