I have an interesting starter circuit issue on a 2001 Toyota Celica (that won't start).

If I have the starter out and have the main positive wire connected, then, run a jumper wire to the solenoid directly, if the starter is grounded to the engine, vehicle fans come on etc. when I set the jumper wire to the positive terminal on the battery.

If I ground the starter directly to the battery, then set the solenoid jumper wire to the positive terminal on the battery, the starter engages and runs as expected.

This seems to be a bit of a mystery. I've tested power at the starter, at the solenoid (when ignition key is set to start) and the power is over 12v. So, it appears the ignition circuit is sending power down there when the key is turned. But the starter fails to do anything. I've also confirmed there is full power at the main power terminal on the starter.

Any suggestions?

Thanks in advance,

MG
 
Have a good look at the engine to chassis ground connection, could be corroded
Hiya...that was exactly the problem. Turns out when the previous owner changed the clutch, he didn't attach the ground cable to the engine very well. Redid that and all was well!
Thanks for your response.

Greatly appreciated!
