STEP 1. Check the starter relay.
(1) Remove the starter relay.
(2) Check for continuity between the starter relay coil terminals.- There should be continuity.
(3) Use jumper wires to connect starter relay terminal STHI line to the positive battery terminal and terminal STLO line to the negative battery terminal.
(4) Check for continuity between the starter relay switch terminals while connecting and disconnecting the jumper wire at the negative battery terminal.- Continuity (2 ohms or less). (Negative battery terminal connected)
- Should be open loop. (Negative battery terminal disconnected)
(5) Install the starter relay.
Is the measured resistance normal?
Go to Step 2. Replace the starter relay. Then go to Step 5.
