im already getting another set of injectors and getting them cleaned. i just wanted some insight on this.

when i first got the car it would never flood, even when i would cut the motor before it was fully warmed up. it would fire up the first try. then out of no where one morning my car is flooded when i try to start it. the night before i parked it, it was fully warmed ( i was driving for like 1 hr.) i made a kill switch and the motor still floods only after it has been sitting for about 8+hrs? i cut the motor off by flipping the switch. i say 8+ hrs. only because one time i had parked the car for about 7hrs and it got lighty flooded but it still fired up after about 3-4 trys. i was thinking maybe the injector gasket/o-rings needs to be replaced too? any insight would be good and this is on a 88 GTU
thanks

change the plugs. I've found that after a good flooding a fresh set of plugs will make the car flood a lot less.

Also check compression.

I say it's the injectors. Injectors that get stuck partially open, will drip fuel, once the vehicle is shut off. Changing the plugs, is also a must.

If a fuel cut switch is used properly, then dripping injectors can't cause the flood problem. IF you just come to a stop and then cut the switch to OFF, you will still have fuel pressure in the rail. I watched this with a fuel pressure gauge on the fuel rails.

IF you come to a stop, and then rev the engine to say three grand or above and then cut the fuel cut switch to off, PLUS stomping the pedal to the floor at the same time, then the fuel rail pressure WILL go to zero in the rail. No fuel and no pressure equals no dripping injector.

ON the next start up the fuel pressure in the rail will be up in under two seconds. Well under two seconds. Been there, seen it
