However, your above post is correct for ‘76~’83 CIS cars but not for the early models. Where did you get this information?

Hi Tony,
I guess it was introduced as vehicles became safer.

I had a broken diode in my relay. And I could see the sensor plate switch spark when I let it back down (long before I got the engine to run)
So I checked out the current flow diagram and traced it back to the fuel pump relay.
I cut the relay open and found the faulty diode.

So I quest the second part of my information I got from experience 😂

Cheers,

Frank
