Relay: Turn on the key and jumper the ECC test connector as previously described.
How does the fuel pump relay work in a Ford?
The fuel injection computer then grounds circuit 1. This activates the fuel pump relay to pass current from circuit 4 to circuit 3. Circuit 3 is the one that runs to the fuel pump (via the Inertia Switch) and delivers the voltage/current it needs to activate.
Why does my Ford pickup have a green relay?
You’ll be able to find out if the fuel pump relay, or the fuel pump Inertia Switch, or the fuel pump is the cause of the No Start Condition on your Ford car or pickup.

How can I tell if my fuel pump relay is working?
Check for voltage on both sides of the switch. If there is voltage on both sides, then check the Pink/black wire on the fuel pump relay: it is the power feed to the fuel pump. Good voltage there, then the fuel pump is the likely culprit since it is getting power.
Where are the fuel pumps on a fox body Mustang?
A big issue that many Fox Body Mustang owners have is finding their Fox Body fuel pump relay locations. It is good to know that depending on the year, the fuel pump relay will be located in different areas. So, we at LMR have provided a quick location guide.
How can I Trick my fuel pump into running?
To trick the fuel pump into running, find the ECC test connector and jump the connector in the lower RH corner to ground. No voltage when jumpered, check the fuel pump relay and fuse links. Power feed: Look for 12 volts at the pink/black wire (power source for fuel pump relay).
