I can hear the fuel pumps hiss for a few seconds when I first turn the key to on. Last night I pulled out and reinstalled the fuel pump relay and kilm relays. I also disassembled the OVP , scraped any corrosion between contacts, and reinstalled in the car. The battery voltage of 12.7 volts was with the car off. I would like to install the new voltage regulator, but I cannot find where it is on the car.

This morning the car started after about 6 seconds of cranking and ran smoothly. I allowed it to come to temperature, shut it down, and it started again easily. I waited another hour and it started easily again.

I think I need to buy some new relays, just in case. Where can I purchase the OVP, fuel pump, and kilm relays? Also, is there anything else I can check to prove to my wife that the car is ok? Thank, Bob.
