THEN, that relay tells the Starter Enable Relay to allow current on thru the system to start cranking. HOWEVER, IF you keep running the tank low on fuel, it will burn up the pump. WHEN the pump overheats, it burns the relays. AQLL of this happened until one day, it would not crank, even when I hotwired the solenoid. I changed the pump, still problems, I ended up changinf the F/P relay. THEN I changed the starter relay. I had bypassed the clutch swith some 20 years ago. This time I bypassed the PASS key. Still problems. The car had sat a few years, so I hit the engine at the quarter car wash. While replacing the injectors, I noteced water in the valley. ASSUMING it would dry up soon. I lef it. It looked like bilge water. Ended up, the starter went under water. So, I ended up rebuilding the starter, BUT I was able to install a longer armature and field circuit off of another Denso starter.

NOW, with the PASS bypassed, the clutch switch bypassed, new relays, and higher powered starter, this motor SPINS. It starts now with snap, and never a failure. I am building these starters for your car, if you are in need of a starter that really cranks. I can also rebuild the alternator and water pumps. Up next is a larger bore clutch master and a HYDROBOOST Power brake booster, using a larger (1 inch) master.
