I am going to throw this out there. I have worked on mostly Honda, Acura, Toyota cars, and have found similar problems on many of the Hondas. I am no trained mechanic, but I usually can trace a problem and do research to fix it without replacing a lot of parts. Fuel pump relays can be an intermittent problem. I would check out the relay and see if tests okay. I usually keep an extra one in my glove box just in case. I have been stranded a few times. They can get corroded or the solder points can get old and crack so that temperature changes can affect whether this is making a good electrical contact. See what you think:
1. Engine stalls
One of the first symptoms of an issue with the fuel pump relay is an engine that suddenly stalls. If the fuel pump relay has an issue while the vehicle is operating it will cut off power to the fuel pump, which will cause the engine to stall. A faulty relay may allow the vehicle to be restarted a short while later, while a completely failed relay will not.2. Engine does not start
Another symptom of a faulty fuel pump relay is an engine that does not start. If the fuel pump relay fails the fuel pump will be left without power. The engine may still crank when the key is turned, however it will not be able to start due to lack of fuel. This symptom can also be caused by a wide variety of other issues, so having the vehicle properly diagnosed is highly recommended.
3. No noise from the fuel pumpAnother symptom that may hint at an issue with the fuel pump relay is no noise from the fuel pump when the key is switched on. Most fuel pumps will produce a low volume hum or whine which can be heard from the inside the vehicle if listened for closely, or from the outside of the vehicle, near the fuel tank. If the fuel pump relay fails, it will cut off power to the fuel pump which will render it inoperable, and therefore silent, when the ignition is on.
Welcome to the group. Thanks for your insight regarding fuel pump relays and other related info. I agree with the three points that you have given and I also travel with a spare fuel pump relay. Hope that you will continue to provide your thoughts as you feel inclined to do so.
