I too had been experiencing starter issues especially under hot conditions.Hit the starter button and hear the starter click but not turn the engine over. If I put it in in gear and bumped the engine it would kick in.Well this week I did the starter replacement with the Toyota starter and all seemed well, finally I thought the problem was solved! However on Saturday I took the Rocket for a ride it was a day about 90 degrees out. And it happened again! CLICK! Enough already! With wiring diagram in hand I began to chase down the problem. Here is what I found... At the starter relay there is a feed wire that is blue and yellow. I discovered that when the click appeared there was a reduced voltage reading to the relay.That blue and yellow wire receives its power directly from the ignition switch after it passes through the fuse block. If I took a jumper wire directly from the battery by passing the ignition switch and the fuse block and touched it to the blue and yellow connector the starter would stop clicking and immediately engage. I am confident this is the same problem many of us have been chasing. Over the next couple of days I will be investigating what the cause is of the reduced voltage and will post again. Hopefully this will prove to be valuable information for others.
