Where are the fuse panels on a Ford Ranger?
Here you will find fuse box diagrams of Ford Ranger 1998, 1999, 2000, 2001, 2002 and 2003, get information about the location of the fuse panels inside the car, and learn about the assignment of each fuse (fuse layout) and relay.
How to test the Ford EEC power relay?
The next step is to verify that the EEC Power Relay’s high current circuit is being fed with battery power too. Go to: TEST 2. CASE 2: Your multimeter DID NOT register 10 to 12 Volts DC. Double check that you’re probing the right wire and repeat the test.
How does the EEC relay in a fuel pump work?
Relay Basics: How The EEC Power Relay Works. This is the circuit that delivers the voltage (and thus current) to the Fuel Injection Computer (EEC Electronic Control Assembly), fuel injectors, fuel pump relay, etc. When the relay is not activated, this circuit is ‘open’, and as such, does not send any power to anything.
Where is the fuse and relay on a 2002 Ford Ranger?

How does the EEC power relay work in a car?
The EEC Power Relay not only supplies battery voltage to the fuel injection computer (also known as the E.E.C. Electronic Control Assembly), but also supplies power to the fuel injectors, the fuel pump relay, and a few other emissions related solenoids. The EEC Power Relay is easy to recognize…
What is the low current circuit on a Ford EEC?
Every Ford EEC Power Relay has two basic circuits and for the purpose of our discussion, we’ll call them: A low current circuit. This circuit can be identified by the wires labeled with the numbers 1 and 2. The low current circuit is the control circuit that ‘closes’ or ‘opens’ the high current circuit.
The EEC Power Relay not only supplies battery voltage to the fuel injection computer (also known as the E.E.C. Electronic Control Assembly), but also supplies power to the fuel injectors, the fuel pump relay, and a few other emissions related solenoids. The EEC Power Relay is easy to recognize…
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. If your fuel injected Ford pickup, van, or car still has the Ford relay, this bad boy will be a green color (like the one in the image viewer).
What does a green fuel pump relay look like?
If it has already been replaced with an after-market one, this relay won’t be green, but will have a gray body. The following tutorial may be of help: How To Test The Fuel Pump (Ford 4.9L, 5.0L, 5.8L) (at: troubleshootmyvehicle.com ).
The next step is to verify that the EEC Power Relay’s high current circuit is being fed with battery power too. Go to: TEST 2. CASE 2: Your multimeter DID NOT register 10 to 12 Volts DC. Double check that you’re probing the right wire and repeat the test.
What does the multimeter say about the EEC power relay?
CASE 1: Your multimeter registered 10 to 12 Volts DC. This is good and tells you that the ignition switch (via a fuse) is powering up the low current circuit of the EEC Power Relay. The next step is to verify that the EEC Power Relay’s high current circuit is being fed with battery power too.
