strange issue i have!
my car runs fine... even when its really low on gas (walboro 255 and 650 rcs)
as soon as i fill up my gas after driving it with really low gas, the car puts and struggles to stay idle when i start it back up...
is that normal?

 

bump...i too have same problem after fillng gas up but even if its either low or half a tank it struggles to start the car after 3 tries.

yeah i don't understand...
gas was near empty... started up fine....
drove a minute away to get gas, started it up, and "put put put"

 

have you checked your fuel filters on both the cars.

 

i had this problem too. My tuner told me to turn the key on and off a few times before starting up my car after filling up with gas to increase my fuel pressure...i guess when you take the cap off your tank, your fuel pressure is gone. Seems to work for me

 

I had that issue also it has something to do with the pressure in the tank or something my mechanic friend fixed for me but i have no knowledge of waht he did exactly. He messed w/ my vaccum hoses and fuel lines

Yep, definitely sounds like fuel pressure. You should hear it all escaping when you crack the fuel cap loose.

Disconnect the evap purge solenoid. Should do the trick.

Make sure you have a obd1 though.....otherwise you'll get a cel.
