Ka24det fuel problem

[lilskyline240]

Ok, so this weekend when i put my turbo kit on, it went really easily with everything except the injectors....im havin MAJOR flooding issues...like the car wont stay running cuz its UNGODLY rich....they is liquid gas coming out of my exhaust....i swappin in 370cc sr20 injectors with new o rings on them all....the ecu is a tune done by enthalpy so i know its not that....like it seems like there is just too much fuel pressure....when i disconnect the fuel pump the car will run just fine at idle...but boggs out when i rev it....then ill connect the fuel pump and within seconds it boggs out and dies, sometimes hydrolocking a cylinder....I am totaly lost....i compression tested the motor before, and it was 180 on every cylinder.....now on cylinder number 3 its 140psi and 180 on the rest...and cylinder number 3's spark plug is ALWAYS coated in gas.....all the cylinders seem to have a gas coating but not as much....cylinder 3 is like filled with gas....so i think its that injector/oring or something in that cylinder that isnt working....

does anyone have a suggestion???? im totally lost now....

I'd check the o-ring on injector #3. Use vaseline when lubing up the o-rings for installation.

also...i had the fuel system hooked up for like 20 miles and it worked fine...i drove all the way to my hair cut apt...and when i got out it just started blowing smoke and running SUPER rich!!!...so idk if my injector seized up or not

i replaced that o-ring like 3 times now and it still is the same

You need to change you oil--all that gas will end up in the oil pan and do bad things to your bearings. Most likely you have a bad injector. if you want to confirm it just swap it for another one of yours and see if it either repeats the same scenario on number three or the problem follows to the new cylinder.

see now the weird thing about cylinder number 3 is idk if its the injector is just puttin out a ton of gas, or my spark plug isnt firing....cuz i changed my plugs out to new ones when i changed out my injectors and through this whole problem the number 3 cylinder spark plug looks brand new...not a stop of carbon or anything on it....looks right out of the box....while the other 3 have some carbon on them and look like they have been used....ima check if im gettin spark today

you might want to try something that controls fuel flow, such as the fuel pressure regulator, or the mass air flow sensor.
