Lately, everytime i fill up, when i go to start the car again it just sputters and dies. i have to hold the throttle open to get it to stay running. i have a walbro 255lph pump right now. the only time this is happening is right after i fill up with gas.

other than the fuel pump, it's mostly a stock 2000 prelude (intake/exhaust). it has 130,xxx miles on it. i'm thinking i may need to replace the fuel pump.

anyone know what might be wrong?

 

Weird, are you letting the fuel pump prime before you switch on the ignition?

My only thought is you're not letting it build up the pressure completely before you try to start it. When you fill up your tank you let some of the latent pressure out when you remove the cap, then you're not letting it build it back up before starting it up. It's probably something else, but just a thought.

 

/\/\ Yeah, just try letting the fuel pump finish priming before you actually start the car.

 

that fuel pump is much stronger than you need, its more than likely making you run rich. I don't know if that is causing your problem, but it isn't helping.

 

i've already tried letting the fuel pump finish priming. i've also tried just priming it several times before starting.

 

Hmmmm...well in that case try going back to the OEM pump.

 

that's what i was thinking. i'll be trying that this weekend hopefully. anyone else? ideas?

 

put back in the stock pump and just filled up. still having the same problem. the car will idle really low for a couple of seconds and then just dies. then i have to hold the gas down to get it to start. for about a minute afterwards i still have to give it gas or it just dies if i let it idle. it's also dying sometimes around a turn when i push the clutch in. any ideas?
