Lx665 starting issue

[fspring7810]

Have a lx665 that from time to time will click repeatedly trying to start. I don't think it's the starter solenoid as that would click only once. Pre heater is fine and does it's thing. It happens when I move the key to start it. Might click 4-8 times quickly but not engage the starter. Is there a relay someplace in the start circuit??

The start relay\solenoid is under the engine fuse and relay box on the left side of the engine. There are two relays there, the outer relay is the start relay and the inner relay is the cold start relay. Rapid clicking indicates low voltage, check your connections.
