2002 Honda Odyssey - Still no start after replacing fuel pump..? Check Main Relay!
Customer's van was stalling. Went to another shop and they put in a fuel pump. Not knockin that because they couldn't get it to act up. So a fuel pump was reasonable. Customer went back to that shop a few times after because it was still stalling. After the van sat for a bit it would usually start. Might stay running for a while or might only last 5 minutes then stall. Fuel pumps typically do not fail like this... Customer then comes to us wanting us to put in their warranty fuel pump. Luckily for me, I was able to have it be a no start long enough for me to do my testing. In this video I go through the full testing of the Main Relay. Verifying everything it would need to function properly and also how to bypass it. These Main Relay's are notorious for cracked solder joints and sure enough that's all this problem was. If I were to add solder to that joint then this vehicle would start and run. This might be something to consider for your own vehicle but as a business that is liable... we're putting in a new part. You don't want to have something else fail in 3 months while they're on vacation then you're on the hook for the tow bill as well! Nobody wins. So we fix it right the first time. If you've got a Honda of this generation then drop a comment to let us know if you've had to change your Main Relay!
