this is for my 240, not my G, sorry guys, but i trust you guys here on the site more than anywhere else.

i began installing my aem ems today, but it wouldnt connect to my labtop, so i pulled it out and installed the stock/enthalpy ecu back in. i didnt touch anything else on the car, not a single thing.

so, i go to crank the car, and it sputters real bad and white smoke just pours out of the exhaust. my WB starts at 14.5, then slowly drops to 10. i look under the car and there is a HUGE puddle of gas on the ground.

the turbo is full of gas, the exhaust, the wastegate, everywhere theres gas.

i thought, maybe while waiting for the ecu to dock with labtop, the fuel pump just filled the system and flooded it. so i unplugged the injectors and cranked it, it actually ran for about 20 secs then died. so i waited a little while, cranked it up, it did the same thing. after 5 seconds, fuel pours from the turbo manifold, on the rear of the engine. it has the stock fuel return system so the fuel shouldnt be overloading the rail and injectors.

so i pulled the fuel rail, pressurized the system, none of the injectors leaked, i did find that 2 of the large black O-rings had some tears around the edges. i checked all the plugs, and only that rear cylinder had gas on the tip. so i let it all drain. i turned it over with the injectors unplugged several times, tried to crank it again, and the damn thing just pours gas on the ground. for some reason cyl 4 is flooding and the fuel isnt igniting.

WTH can this be? can it be the torn o-rings? or something else. i know the 02 sensors are soaked, along with everything else, its really starting to **** me off.

 

got it figured out, thanks guys, lol.

 

What was it?? I'm curious now.. HAHAH~ Glad you fixed it..

 

some wires got crossed so the injector was getting a constant current, filling that cylinder with fuel. yikes!

 

good thing u found that.....better thing u didn't take a smoke break!
