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.

Chris inspected a used car for me. He arrived promptly and called me right after inspection to deliver the results, as well as answer any questions I had. I look forward to working with Chris in the future.

Toyota 4Runner V6-3.4L - Brake Warning Light is on - Las Vegas, Nevada
Yelp has, once again, helped me find a very reliable/dependable service. Patrick was mentioned more than once on all the reviews so when I booked my appointment with Yourmechanic, I was crossing my fingers that they would send Patrick to look/inspect and work on my truck, and they sure did! Patrick showed up at my place of work as scheduled (7 a.m). Talk about prompt and punctuality (and utter convenience for me)! I contacted Yourmechanic because my brake warning light indicator suddenly lit up. I also decided to get the valve cover replaced since Meinekere commended it every time I would get my oil changed. Yourmechanic quoted me way lower than what Meineke quoted me for the same work/service. 25 percent less, to be exact. Upon inspection of my truck, he made recommendations for the needed service/work but, surprisingly, not including the valve cover and gasket replacement. I found Patrick to be very professional, efficient, honest and highly knowledgeable. Most importantly and what matters the most is that he is genuinely a very honest man (unlike some, if not most. of auto/car mechanics who will take advantage of one's knowledge, or lack thereof, when it comes to car maintenance/repairs/service) . I found his dedication to his profession remarkable as he spent just about all day as worked on my truck in the parking lot under the desert sun! After he's done with the service and test-driving my truck, he gave me some "post-service" tips/recommendations. Patrick is THE man! I found me my regular to go mechanic!

Came out this morning because our Toyota 4Runner had trouble starting. Real quick inspection, discovered corrosion build up messed up the battery and replace the connecting cable. This is something that I could do but he also did an inspection of our vehicle and informed me of some minor things to take care of. Fantastic and quick. Highly recommend.
