What is an EEC relay?
What is an EEC relay?
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. stands for, it’s: Electronic Engine Control.
Where is the fuel pump relay located on a 1992 Ford Ranger?
It’s location is in the fuse/relay box under the hood. It’s a 20 amp fuse in position 23. If the fuse is OK there’s a fuel pump shut off switch located under the the glove box just above the carpet.
Where is the fuel pump relay located on a 1990 Ford Ranger?
The fuel pump relay is under the under hood fuse panel on the passenger side, remove the 2 bolts that hold the panel on and turn it over its right there (green one) unclip it and then unplug it.
Where is the fuse and relay on a 2002 Ford Ranger?
Using a 2002 Ford Ranger I point out the location of the AC compressor clutch relay and the fuse. This information is applicable to any Ford Ranger that has a 3 or 4 liter Category Autos & Vehicles Show moreShow less Loading… Advertisement AutoplayWhen autoplay is enabled, a suggested video will automatically play next.
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.
What’s the color of the EEC power relay?
The EEC Power Relay is easy to recognize because it’s usually a brown color. If the EEC Power Relay has already been replaced, you can still recognize it by its brown colored connector. In this ‘How To Test’ article, I’ll show you how to test it on your Ford car or pickup in a step-by-step manner.
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 does the power come from on a Ford EEC relay?
This voltage comes from the ignition switch. Power (in the form of 10 to 12 Volts) is always present in circuit 4 . This voltage comes directly from the battery positive terminal across a fusible link on the starter motor solenoid (on the fender). Ground is always present on circuit 1.
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).
The EEC Power Relay is easy to recognize because it’s usually a brown color. If the EEC Power Relay has already been replaced, you can still recognize it by its brown colored connector. In this ‘How To Test’ article, I’ll show you how to test it on your Ford car or pickup in a step-by-step manner.
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.
