Fuel Pump Operation - 83 Turbo

Recommended Posts

Hello all; I am working on a friends newly purchased 83 Esprit Turbo. First of all this forum is great! I have already fixed the bad gas fumes, sloppy shifter, and some other gremlins. Because of your help and knowledge he thinks I'm a wizard (I did reveal my sources).

This car has several amateur repairs, but I think we got it before something was really fouled up. My question relates to the fuel pump operation. Every other car I have driven or owned with an electric fuel pump starts the pump for a few seconds when the ignition is turned on. Then the pump turns off until the car is started. This car has had an aftermarket relay installed and some extra wires spliced in to run the fuel pump. However, once the key is switched on the pump runs all the time. Take a look at the photo and you will see what I mean. How is it supposed to operate.

Also in the picture:

What's the little green light for?

Is that connector the On Board Diagnostic Interface; OBDII?

And finally what was bolted to the 4 studs on the electrical panel cover?
