fusible links?

If you have power from the ignition/switch wire at the relay in the start position and the starter turns over when you jump it. The problem has to be the relay, the neutral safety switch wire or a bad connection between the relay and the starter.

1) If your fusible link is bad then you won't have power to any of your assessors so if your radio, interior lights, turn signals and other things work then your fusible link is fine. The fusible link is the wire that comes from the relay and supplys the car with power, usually it has a plastic tag molded into it.

2) double check that you have power at the large terminal of the relay.

3) Is the shifter linkage adjusted correctly? Try and start it but hold the key in the start position while you move the shifter from park to low. If it don't make contact when you do this, then take a piece of wire and bypass the neutral safety wire on the relay, just unplug it and connect the terminal to ground. Then see if it turns over.

If it turns over during that then you know the problem is within your neutral safety switch or shifter linkage.

4) Will it turn over if you jump the two larger terminals on the relay? It should turn over this way even if the relay is bad unless you have a bad wire or connection between the relay and starter.

If still no contact, then you know the problem is between the relay and the starter. but if it turns over there then the problem is the relay.
