Sr20det flooding problems!!!! please help

[sik-s14]

Sorry for the book just wanted to let everyone know some background info on the car its a 1995 240sx with a sr20det motor swap from an s13 and a rb20 tranni . i bought this car and am now experiencing trouble with my motor flooding. first off i bought w/o driving it because a head on collision caused it to not be in operating condition. i went on good faith everything was good and i heard it start up that was it. the front end damage wasnt to major no bent frame or anything. but two weeks out of the shop the tranni went out. ive tried to contact the guy who sold me the car with no luck. he is an a** lack of a better word. lets just say he saw me coming a mile away.but the symtoms are1 it will start up cold but if i give it any gas it floods. it will start up again but with trouble2 if im lucky enough to get it out of the driveway it floods if i decide to let off the gas for any reason..... stop lights, stop signs, avoiding other cars ect....lol3 gas smell from 20 feet away.4 fouled plugs every time i pull them. 5 bogging at around 3000 rpms 6 black and gray smoke and liquid coming out the exhaust ... maybe from the excessive gas.7 back fires when accelerating but not all the timei have read other forums with similar are the same symtoms where the o rings are injectors are at fault. ive replaced the o rings and injector seem fine. when running i pulled the wires to each one and the engine bogs on every cylinder. ive checked the coil packs and they are fine. changed spark pugs. could the fuel pressure regulator be at fault? i looked at mine and its from greddy but idk how old it is or anything. ive noticed i have a vacum leak on my throttle body on the bottom. i looked on a diagram and its supposed to run to the recirulation valve or something but i looked in my engine bay where is should be located and the is two open vacum lines with no canister or w.e could this be a problem also? im running out of patience this car is nice with over 15,000 invested in it turbo upgrades ect. (well thats what i was told) but its killing me ive had to put more than 3000 in it this summer and havnt gotten to drive it ... front bumper , radiator support, rb20 tranni, custom drive shaft, ect. can anyone help me? i dont have the patience for crappy shops around here and i would much rather someone with experience on sr20s help me..... Please help me !

pull fuel rail out and prime fuel pump. See if fuel is leaking past the orings. Pulling off the plug for the injector and seeing the engine bog will not tell you if there is a leak.

What size are the injectors? Is the ecu tuned?You said it has turbo upgrades..

[I ask good questions]

coolant temp sensor?

[duffman1278]

Coolant temp sensor seems unlikely. How much PSI are you running on FPR? Verify that it's within spec.

Checking your injectors is definitely a must, although the injectors "seem" fine they may not be in reality.

While doing these things pull out your coilpacks and spark plugs so that you can allow the gas to evaporate from the cylinders.

sounds like a maf issue.

Do the good ol "check ecu" for codes

Process is:

:Get the ecu out in the open but still attached to main harness: Examine ecu for the service LED bulb and right next to it will be a very small screw:Turn the key on to the ON position (do not start). Light on ECU should be lite: Now take a tiny Phillips Screw driver and turn the tiny screw on the ecu clock/counter clock wise till the LED starts flashing

If it reads code 55 everything is normal. Chances are if it stalled it will automaticaly throw a "crank angle sensor". Dunno why

heres a link to the codes and how to count them

Try this then get back to us

I HIGHLY doubt that you have an R32 transmission in your car. I would start with things like checking the tps sensor, making sure the maf is clean, timing, and idle adjustments before you start replacing any parts. Checking for leaking o rings like the others suggested is also a good place to start.

im starting from the top and working my way down answering questions: idk what size injectors they are they may be stock. the guy that sold me the car will not answer my calss texts, or vmails so idk are they classified by color? thats prob a stupid question i do kno they are red ... and my car has a stand alone engine managment system on it from greddy but to tell you all the truth ive never really messed with it.... the turbo i have on my car is made from precision its a t3/t4. im running around 15lbs at low boost setting on my ems and at high boost 21lbs....

how exactly do i test my fpr pressure. ive never messed with it b4?

and sorry bout that.. thats a typo i dont have a r32 tranni its an rb20 tranni my bad..... but i will check everthing you all have brought to my attention this weekend and get back to you all by sunday thanks again for the help.....

[the converted]

Judging by the turbo and boost number, the injectors are not stock and you probably have a z32 maf installed as well. Judging by the sounds of the previous owner, he did a ton of work on the car and never got it running right before he got rid of it, so I would be willing to be that the greddy computer doesn't have anything close to a proper tune, and you're going to have to find a tuner in your area to help sort it out.

[sik-s14]

you are correct the converted it does have a z32 maf on it... i just hope for my sake that it doesnt need the proper tune because i dont know of any place around here that can tune it for me.... i dont guess it would hurt tho to do everything that everyone on here as told me to check .... ill do that and let you kno hopefully it will fix it ... but i did check the oil today and it needs changing it reeks of gasoline not good at all could be caused from the flooding also ....

[the converted]

If your oil reeks of gas, then you might have washed out the rings from it running to rich. You need to do a compression check and see what you're working with. If no one can tune in your area, your best bet is to make sure of the flow rate of the injectors, and then get in touch with enthalpy or jwt and have them chip your ecu and get rid of the greddy unit.
