XX Boosted Si XX

Hey just wondering if anyone has a hard time starting there car after they fill up. I have a boosted civic, walbro pump, aem fuel rail, regualtor, etc....car is fully tuned runs great, just after i fill up it takes about a minute it seems to build pressure and run again. Weird! Anyone ever experience this?

it almost sounds like ur talking about flooding the motor. Does it do it when u drive your car, turn it off, then try to turn it back on 2-3 min later (without filling up)?

let me guess you're running and obd1 ecu on an obd2 motor?
disconnect the evap purge solenoid

next time you go to fill up, turn the key to the on position without turning the car on (2 clicks). You'll hear the pump come on then the sound will stop. (maybe 5-10 sec.) then turn the key the rest of the way, see if it still does it.

So you just disconnect that plug? DO you just leave it like that open?

Be careful when you unplug that, i did the same thing and all it did was lead to a terrible vac leak, engine revved really high and i shut it down.
