Hi DonPlugged in.
You are testing if voltage is present to the relay and if the relay is functioning.
The pins 30, 86, 87 need to show battery voltage +
Pin 85 needs to show ground.
Power goes in at pin 30 and comes out at pin 87 if triggered by pin 86
I am looking for some help please ( apologies for hijacking this thread )
On my main Relay , I have the ground on 85
I have 12 volts at terminal 30 but nothing at 86 or 87
My car turns over but has no power getting to the fuel pump . I do have 12volts at the fuel pump relay but no signal/ switching voltage there.
I also have no spark at the spark plugs.
I also do not hear any clicks or blips from the injectors with the key in the on position and I open the throttle fast as you suggested.
She’s a September 1973 built 3.0csi.
When you mention checking the pins at the ecu , how do I do that . The cover seems to be crimped on with tabs .
Do people bend those back for access to the ecu ??
Oh . I did test both the main relay and fuel pump relay off of the car on the bench and the both work perfectly when connected to a separate 12 volt supply.
Any help or advice would be great thanks
