Major fuel problems...plz help

[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....

Replace the injector O-rings and this time, before installing the injectors, use a generous amount of wheel bearing grease to lube the O-rings.

I had this same problem before and it was because of torn O-rings as a result of being too dry when I installed the injectors.

Don't worry, buddy. Do this and your engine should run just fine.

i used vaseline on them because i heard that is what you are supposed to use....ill try the wheel bearing grease....and im supposed to put alot on there??

[KATwo40]

Yeah, man, put clumps of it on there. Worst thing that happens is the fuel washes the excess off and burns it in the cylinder.

[lilskyline240]

ill try that and see what happens

yeah its the lower oring thats your problem. same shlt just happened to me recently with my deatschwerks. i first installed them with the lube they came with and had some other problem. the car ran, but would die if i let my foot off the gas (this was from having the iacv nipple before the maf and not after). i installed my stock injectors just to see if it would fix the problem but didnt. checked my plugs and two of them were coated in gas. pulled the dipstick and it reaked of fuel. so i pulled the rail off with the injectors still attatched and fuel lines. turned the key so the pump would come on and the two where the plugs were wet i could see fuel pissing from the injector outlet. i ended up pulling of my injectors and alll of the orings on the bottomrs were torn. this was because when i reinstalled the deatschwekrs after changing out my stock i didnt lube the orings back up. i thought they would be fine just to put in. i noticed they didnt pop in like before when they were lubed. so i got new ones from nissan (both upper and lower) and they had them in stock. this time when i put them on i lubed them up with some motor oil and they poped right in. now after they pop in, spin the injector in the rail a few tims to make sure the orings are properly seated. an easy way to test to make sure all of your work is good is to keep the rail off the intake, with your fuel lines connnected to it still, and turn the key to turn the pump on. make sure you have no leaks and bot the rail back to the mani. make sure you drain that oil with some fresh stuff because i know its full of gas.

Change your oil NOW. Before you have a spun rod bearing like me. I had 2 crushed lower orings. Thought it was i needed to tune my car. Drove 3miles and spun a rod bearing and runined a cam. Start the car and let it run for abotu 30 seconds If there is any misss then shut it off and immediately pull the plugs. See if they are wet. If one is then that's your leaking one. I pulled my injector clips. It made the engine run better. Checked thta plug and sure enough that was the bad oring.

figured it out...my 370cc injectors were shot...so i went back to my stock ones till my Deatchworks get here on friday....and i had 1 bad plug that wasnt firing....but its all good now
