worst flood ever today --- have been searching for hours
okay .. i have a huge description written up, but im going to try to keep this short
mods
RotaryResurrection Rebuild (streetport) around 6k on it approx.
Walbro Pump
Rtek 1.7
720 secondaries
Safc-II (mostly untouched)
No emissions
Symptoms:
Car fires up first time in the morning almost always
Usually have to use the fuel cut switch that landers installed for me to get it started (unless its been sitting for a long time)
Plugs foul extremely easily/quickly
car idles funny (i assume due to richness, as the safc helped it out some)
car idles and sounds the best when its timing is advanced
if i set the timing to completley dead on it idles low and like ****
When i first got my car back from landers (about a year ago now) it would fire up instantly about 90% of the time ... the other 10% required the cut switch .. but it would always eventually start (never took more than 30 seconds approx to get it to start)
injectors were cleaned about a month ago when i installed my rtek 1.7
today the car flooded worse than ever ... took over 30 mins of me trying various things to finally get it going again (pulled egi fuse, used landers fuel cut switch, and used rteks pedal to the floor method) - nothing worked
pulled the rear rotors plugs and cranked with no EGI fuse ... no fuel came out nor did it reak of fuel .... the plugs were also not drenched with fuel and didnt smell like straight up gas
1. could a bad FPR be causing this?
2. Temp sensor in the throttlebody elbow be bad and causing this?
3. surely its not bad compression ... the car still screams when its actually running and it was just rebuilt less than a year ago
4. injectors were cleaned about a month ago ... cant be them ...
5. ecu was modded by rtek and they commented that it was one of the best condition ECU's they had seen
6.should i install one of those H connectors for my fuel lines ..??
most of the searches i have found point out the obvious over and over
low compression and or bad/leaky injectors
less than a year on a rebuild that hauls ***** when running ....surely its not low compression ...
injectors cleaned less than a month ago .. surely that cant be the problem
why did all of a sudden the flooding get REALLY bad,
and how could it be so bad that the fuel cut switches wont effect it?

Is the SAFC powered up and running? I thought maybe the Rtek and the SAFC don't like each other. Your car was running fine before with just the SAFC. I think some tuning needs to be done since you threw the Rtek and 720's at it at the same time. But I don't know ****, I just got my turbo

the safc has the default settings on it .. no correction what so ever ...
im going to disconnect it completely and go from there ....
going to change the cone filter, 02 sensor, and remove the safc completely ....
i know the injectors arent leaky, and surely i dont have that low of compression ...
this sucks

Have you tried pulling the codes yet? Try to initialize the SAFC and see if things change and then set back to the correct settings, flap type, 4cyl diagonal top right arrow, 5in 5out (I think for s4).

nah i havent tried that
i think im just going to unplug it and see what happens ...
technically i should be able to run 720 secondaries with the rtek with no other fuel control needed ..
when i first installed it (rtek 1.7) i just zeroed out the safc assuming that would stop any correction (which im sure it did)
its just wierd that its never flooded this bad before and now all of a sudden its god aweful
surely the injectors havent crapped out yet? same with the compression?

Maybe a connection got loose on one/more of the wires to the SAFC. You can go to the sensor check to get an idea of what may be wrong with any of the sensor inputs there.

Have you got it running since this morning???
I ask because, if you still havent got it running, there might be a bad connection where the S-AFC was wired in.
If you have already got it running, disregard.
(It might be something else, but the connections are easy to check)

you cant just unplug the safc because the air flow signal runs through the safc, you have to have the safc setup right or it wont run right. the sensor type and the 5in 5out stuff has to be right i dont know what setup is for the fc but ive used it on other cars and it has to be right.

Correct, but if the car hasn't turned on yet, the wire for the AFM signal might be disconnected.
Thats what I was leading up to. The wire is very easy to check, maybe 10 mins tops. Its free and quick and MIGHT be the problem.

SAFC's have nothing to do with cranking, all they do is alter airflow signal (safc= super airflow converter)
the ECU has a map specifically for cranking, which has nothing to do with the airflow signal.
now as for it being hooked up wrong or something like that, i have no clue. but i'd look at other things before the safc

now, I'm not the sharpest knife in the drawer, but what makes you think that it's flooded, if there's no sign of gas in the housing, and it's not starting?
Does the sAFC connect directly to the injectors? If so, I'd start checking those wires.... hell, check em anyway, sounds like a loose/poor connection to me.

EDIT: It really doesnt sound like the car is flooding, that is why I point to the electrical connections where the S-AFC is connected.
EDIT #2: If you connected the S-AFC per the manual and used the supplied hardware, you should be able to disconnect the AFM signal wire that gets "sent through" the S-AFC, and bypass the S-AFC. Essentially the S-AFC will show all of its readings, but it will not convert the factory AFM signal. The car should operate as normal.

i highly doubt its the safc ... when i first got the car back from landers i had a problem with the car not starting cause of loose wires (he only tied the wires together incase i wanted to change it later), but i have since had those wires soldered .... i highly doubt thats the problem
has anyone installed one of those H valve things into thier fuel lines? i tried reving the car up to around 3 k and then killing the gas via the switch ... that seems to help a little bit ...
bad FPR maybe?
i caught a wiff of fuel every now and then when it flooded really bad so im sure its flooding ...
maybe my plugs are so fouled they just cant handle a wee bit of excess fuel?
my plugs have been fouling out extremely quick lately ...
im going to do a general tune up and hope for the best

yeah... and if you have it hooked up wrong like you're saying, that leaves the ecu with no AFM signal. which, granted, will not let the car run, it WILL STILL LET THE CAR FIRE UP but it will only run for like 1 second then die if you have no afm signal. you ever left your AFM unplugged and tried to start the car? it starts, it just instantly dies.
if its flooded it wont fire at all...
so, its probably not the safc.

hey man i'll be in nashville friday night if you still dont have this thing running. we could come check it out and try to help ya out. 
1. its not the SAFC. the ECU gets the car to initially fire up off of the cranking fuel/ignition map, totally seperate from the airflow signal. even if you did have the safc wired up wrong (which would make you have no afm signal to the ecu) it would still crank, fire up, then run like **** and die.
2. no clue what you're talking about here. but the problem lies in the cranking of the engine, so unless your injectors are way fucked, turning off the fuel via your switch when you turn the car off shouldnt do much.
3. FPR's dont go bad. and if it was bad, you'd be running less pressure. and you can run a car with no FPR just off the small amount of pressure provided by the fuel pump alone. this lack of pressure would be a LACK of fuel, not an excess of it (which seems to be your problem) unless somehow your fuel pressure shot UP from this..
4. plugs really dont just foul out of nowhere, but feel free to change the plugs. how old are they? check out the plug and see how worn they are, but i've never heard of a car totally not firing because the plugs are bad... it doesnt take much of a spark to get a car to fire during cranking. putting new plugs in never hurts though, could rule one thing out.

I've read that if you let 'em die out with the fuel cut after un-flooding a lot, it can glaze over the injectors as it leans out. I still don't think it's the injectors though.
