The Fuel Pump Relay Location on a 1999 Ford Escort
The fuel pump relay on a 1999 Ford Escort is located in the power distribution box, also known as the Constant Control Relay Module (CCRM). The CCRM can be found underneath the hood or affixed to the driver’s side fender wall. The CCRM is a fuse box within the engine bay of your Ford Escort that delivers power to the fuel pump. When the fuel pump relay malfunctions, it can result in engine stalling or the engine not starting at all.
Please note that the fuel pump relay is part of the CCRM and cannot be replaced separately. If you suspect an issue with the fuel pump relay, you may need to replace the entire CCRM unit.

Where will I find the fuel pump relay?
Find the fuel pump relay in your vehicle’s fuse box.
The main fuse box is usually located underneath the hood near the front of your vehicle, but there may be a smaller fuse box under the steering column inside your vehicle as well.
What are the symptoms of a bad relay?
A bad main relay can cause problems like a no-start condition, unreliable vehicle ignition, an engine that won’t stay running, and an illuminated check engine light. Relays are electronically-controlled switches. They connect or break paths in a circuit to control electric currents and their respective devices.
How do you reset a fuel pump relay switch?
Once the vehicle determines the systems are safe, then the vehicle allows you to restart. The fuel pump shut-off switch is located behind an access panel on the right side of the luggage compartment. The fuel pump shut-off switch has a red reset button on top of it.
What triggers the fuel pump relay?
In a typical automotive fuel pump circuit, a control module activates the relay. When the module deems conditions are correct, it supplies ground to the coil inside the relay, causing current to flow through the coil. The current flowing through the coil creates a magnetic field that pulls the relay’s contacts closed.
Is it OK to bypass fuel pump relay?
Safety concerns: The fuel pump relay serves as a safety feature to control the operation of the fuel pump. Bypassing the relay can eliminate this safeguard, which can be dangerous in case of an accident or other emergencies that require the fuel pump to shut off automatically.
How do you know your fuel pump relay is going bad?
Misfire under load Surge. And run rough anytime fuel pressure drops engine performance suffers immediately check engine light on many vehicles. There are fuel pressure sensors in the fuel rail.
What will a bad fuel pump relay do?
Engine stalling or failure to start: A failing fuel pump relay can result in intermittent or complete loss of power to the fuel pump. This can lead to engine stalling or a no-start condition, as the fuel pump fails to deliver the required fuel to the engine.
Where is the fuel pump reset switch located?
If it was in the up position. Then it means the switch is off and power isn’t going to the fuel pump this switch could be activated if you’re in an accident. If you have a blown tire.
Will a fuel pump work without a relay?
Will a fuel pump work without a relay? It would if you hardwired it with heavy enough wire. It would work continuously .
Does the fuel pump relay turn on the fuel pump?
The fuel pump relay plays an integral role in getting fuel to your engine for combustion. Powered by the ignition and/or powertrain control module (PCM), the fuel pump relay’s main function is to provide the fuel pump with enough power. When the fuel pump relay isn’t working, then the fuel pump cannot either.
