I know what the problem is, Its a leaky injector.. which im going to fix.. but i need to get the peice of **** started to do some other work on it.. and i dont feel like letting it sit for 6 hours.. what can i do to lose the gas in the system?

Pull the plugs and egi fuse (in the engine bay fusebox), crank it, fuel will come out.

You should also wire in a fuel-cut off switch for until you can get your injectors cleaned.

Under the dash above the pedals, there is a black and yellow relay. take the middle wire, and wire in a toggle switch. Use this switch to cut the fuel to shut down the car.

The EGI fuse is the 2nd one in from the right side when your facing the front of the car (its green). Fuse box is located on drivers side. Fuel cut switch (link) is a good plan.

thanks guys.. I am quickly becoming very frustrated with this car.. I let the car sit a few days and it starts fairly easy.. now whatever i try now i canot get it to work...
I tried taking the fuse out, and once i get it all back together and try starting it.. it starts but it chokes for a couple of seconds then dies...

All the other times that i could get this thing going it does the same thing but seems to burn off some **** then starts running properly..

could this still just be leaky injectors? or possibly something else? im sure its stil getting too much fuel but......

I am just extreamly frustrated.. I just want the damn thing to run...

whats that all about with the ATF trick.. wouldnt having atf in your motor make it harder to start?

Try the EGI fuse, that works well for unflooding.

If that doesnt work try pushstarting the car. One time my car was badly flooded and I had 2 friends push the car to maybe 5-10 MPH and then you dump the clutch and that might work. Key should be in the on position


good luck

StinkyFatPig

yeah I did try that.. It helps.. but the car chokes a few seconds then stalls.. when it does start.. as in the past it chokes that like for a few seconds then it starts running fine..I just cant get past it.. I have a feeling its just flooded masivly.. I think the injectors are just fucked and letting too much fuel in..

it also seems that since the gas is sitting in the chamber for a while it starts to eat away at the carbon build on so then the fuel is dirty, which probably makes it even harder to get going..

thanks for the ideas.. please keep them coming

StinkyFatPig

forget it.. I am just going to get those injectors cleaned.. at this rate i am going to have a stroke by the end of the day.. thanks for the help guys!

Doesn't anyone know how to unflood an engine anymore?!

After pulling the EGI fuse or disabling the fuel pump, you crank the engine with the gas pedal floored, so that air is pumped through the engine and clears out the excess fuel. Then turn the fuel back on and try to start it.

Yes, this is correct! Also, im not sure if S4 cars have it as im just plain too lazy to run a search, but on S5 if you hit the pedal to the floor all the way the fuel is shut off and you get nothing but air.

presetlimits

no the S4 isnt the same way as the S5 as far as holding the pedal to the floor

NZConvertible

No, I wasn't talking about that feature on the S5. The unflooding method I described above applies to any engine (piston or rotary) in any car. The important bit is that the throttle is held wide open so air is pumped through the engine while cranking. The S5 ECU disables the injectors when you do this, meaning you don't have to pull the EGI fuse or use a fuel pump kill switch like you do with an S4. You still need to hold the gas pedal down whatever model you have.
