Hey am a new mbr here..going thru the exact same issue..Infact it didnt start a mrng in Dec2010. Since then i started using my TACOMA. It did give occasional starting troubl..1 day i was at a light and it just SHUT OFF. Upon coupl tries it started. I did try with jumper cble frm Tacoma(New batry)..hear only clicking.I already took the starter off the camry(Hope its the right part). Questions are :
1.What do you guys think of the symptoms.?
2.Is the AM2 fuse in the fuse box.?
3.Which is the relay side in the picture..?
thnks in advnce.

 

When the ign key is turned to Start, power flows from the AM 1 fuse through the ign switch, through the Part/Neutral or clutch switch safety/lockout switch to the starter relay solenoid coil (might be a Black/white wire, relay terminal labeled No 1).

 

Its the other side of the circuit that is not providing 12V to the relay side of the starter relay. I get 12V at the AM2 fuse and from the other side of the fuse, I get continuity to the starter relay.

 

After turning it off it won't start again. I don't get 12V to the input of the starter relay from the ignition switch but when I turn the key on I get continuity from the fuse that supplies the 12V to the ignition switch to theinput of the relay.
