My car is having trouble starting… wants to fire up and will for maybe 1 second and then stops. I used a code reader and it come back as a bad fuel pump relay. I now have the two fuel relays on order (bought the little green one to be safe). I also hear a click coming from the fuse box under the hood on the driver side (no idea what’s in there) but noticed a noise every time I turn the key to off. The fuel pump was replaced a handful of years ago and I’ve driven maybe a couple thousand miles since. Not sure if it’s priming but didn’t check if it’s getting power either. Will be the next step if the relay doesn’t solve my issue.
So my question is, if the fuel pump relay is bad why would the car seem to start and then stop? Is this a sign of the relay tripping? I even pulled the plugs and can smell fuel on the end of the spark plugs. Would that not be a sign that it’s getting some fuel? I’m suspicious that the relay is not the problem but it’s what the code reader came back with so will start there.
When connecting the battery up a few days ago it did spark a bit… that may be totally unrelated but putting the information out there.
Car ran fine a few days ago.
Thanks for the help
UPDATE: Fixed
For those searching and finding this later. My M has been sitting for some time with the same gas in the tank. After going through the typical, fuel pump (tested/working), new fuel pump relay, new fuel filter, and new fuel pressure regulator all with no luck. I figured maybe it has bad gas or the gas collected a bit of water. I suspect a bit of water in the tank given I could still smell gasoline on the plugs.
Pulled the fuel pump and hand pumped as much of the old gas as possible out of the tank. Then filled it up with a few gallons of fresh gas. Started right up and I had a huge sigh of relief.
