MFI fuel pump relay questions
In testing the socket where the red relay plugs in #30 goes to the fuel pump, what voltages should I get from 87 and 87a when cranking and when the air sensor plate is lifted?
Also, which terminal should have a constant 12V? I'm not getting 12v down to the fuel pump, but if I feed 12v into terminal 30 on the socket then I do get power to the pump and can start the car and drive it. |

There is no relay for the fuel pump in an MFI car.

It is a '77 carrera 3 and I thought it was mechanically fuel injected. I have a red relay under the hood that is labeled 'fuel pump relay'
