What is the Electronic Control Relay all about?

A wide range of electronic systems must work properly in order for the vehicle to operate. That means there is a need for several different controllers to ensure proper operation. One of the most important is the electronic control relay. You might be more familiar with the term “main relay” because of its role in vehicle performance.

The electronic control relay operates the fuel pump and sends power to the engine’s injectors. Without the main relay, fuel will not flow from the tank to the engine, and your injectors will not atomize gasoline into the combustion chamber. In short, your car wouldn’t run. Electronic control relays are subject to failure from a number of different problems, including outright failure, heat damage, cracked solder and more.

Keep in mind:

The electronic control relay may not operate, or may operate intermittently depending on the source of the trouble.
A number of other problems can masquerade as a main relay failure, so it’s vital that you have one of our expert mechanics diagnose the issue.

How it's done:

The electronic control relay is located and accessed then verified it needs replaced
The defective relay is removed from the vehicle
The new electronic relay is installed
The components that the electronic relay operates are checked for proper operation
The vehicle is road tested for proper operation

Our recommendation:

Traditional turnkey ignition the relay will click three times during the starting process. If you listen closely, you should hear a single click when you turn the ignition to “on”. You should hear another when the Check Engine light turns off. Finally, there should be a third click when you turn the key to the “start” position. If you do not hear a click at any of these three points, there may be a problem with the electronic control relay. Have one of our expert mechanics diagnose and replace the relay if required.

What common symptoms indicate you may need to replace the Electronic Control Relay?

Engine doesn’t start, especially in cold weather
Engine may not start a few minutes after turning it off
No sound from the fuel pump when the ignition key is turned to “On”

How important is this service?

Given the fact that the electronic control relay powers the fuel pump and your fuel injectors, it is essential to replace a faulty one. However, many other problems can present similar symptoms, so it’s very important to have the issue diagnosed by one of our expert mechanics.

BMW 540i V8-4.4L - Car will not turn over - Los Angeles, California

This guy is really honest!! I actually had an issue with Battery but a 3rd party guy told me that there is an issue with my alternator. I used yourmechanic and requested Ruben to fix my Alternator. Instead of blindly replacing the alternator, he performed some checks and found out that my car battery was BAD. Thanks Ruben! Appreciate it.

BMW 540i V8-4.4L - Car is not starting - Newark, California

Amor's expertist has save me a lot of time and money in getting the correct diagnose on my car's problem. He was able to fixed the choking problem compared to 3 experienced mechanic that try to fix the problem previously replacing parts that is not really related to the problem. He cleanly reset everything and now I'm worried free about the problem already. He's very good especially on European cars. I'm very much satisfied with the service & 100% definitely recommend him to my friends up to my relatives.
