Having an issue with my fuel system..im running 93 with 750cc DW injectors and a brand new Walbro 255lph fuel pump..Everytime i fill up gas, i end up having to pump the gas pedal to get the car started as i am turning the key.. usually takes 3-5 times of trying this to get it going..heres what i have done already,

Changed the Fuel pump
Changed the Fuel filter
ran sea foam through the gas system..i am thinking that the fuel lines might be clogged or injectors need to be cleaned...any suggestions would help.. thanks guys!

do you hear it prime?

 

could be a tune thing also

 

yea i hear it prime then i turn the key..i hope its not a tune issue

 

Do you have any problems filling up the gas tank?

For instance, if the pump clicks off when you know the tank isn't full - maybe once or twice.

Does the car run rough for a few moments?

It might be a tuning issue if you *just* installed that fuel pump and / or injectors.. otherwise, just wondering if it could be those stupid rollover valves in the gas tank.
