i finally got her to start up after sitting flooded for the whole winter. i just squirted wd-40 in the UIM nipple and away she went.......it was idling (if u can call it that) @ 5000 rpm though...i let that go on for about 10 seconds then shut it off......havent tried again cause its 5 am here right now and my neighbours will get pissed.......just a little concerned about the 5000 rpm idle .........can any one help?

Check the thottle cable, make sure it is not binding.

Smitter

throttle cable was good. that was the first thing i looked @ after shutting it off.
Anything else i can try?

wait a sec, you can fix a flood by just "squirting" wd40 in the UIM? TELLL MEEE PLEASE!!!

Smitter

its far from stock.........power fc would be the only relevant mod for this problem (i would think)
its 11 am here now so i am gonna go try it again

how do you fix a flood like that?

Smitter

ok...well turns out the throttle cable for the cruise was sticking a bit.....i got the car to start up again but i had to again spray wd-40 in the intake before it would....it was still idling quite high (about 2500 rpm) i let the car warm up to operating temp and took it for a rip around the block. it was running good. shut the car off when i got back home and tried to restart it.......it wouldnt go...wtf?

Smitter

eightsixlife......dont jack my thread.........but if u are having flooding issues u can spray the wd-40 into the uim where the boost gauge hose is located .spray using the red straw for about 5 seconds....let it sit for a minute then try starting. hold it floored on and off as u do so....it worked for me

I'd still pull the spark plugs and de-flood the engine. If it was sitting all winter flooded. You've got some serious crap in there. I'm willing to bet that you're plugs are soaked and I would probably replace them after sitting all winter with fuel on them.

Has your PFC been tuned and do you have any aftermarket fuel components? You said it was heavily modded so I'm assuming bigger injectors and whatnot.

Why did it flood in the first place?

Smitter

i did take the plugs out and cleaned them thoroughly..new plugs are definetly an idea. but i figure if i can get the car to run once. the plugs should be alright. i have a supra fuel pump but am curently still running the stock injectors. ( maybe i should have said the car is moderately modded) the car has not been dyno tuned. but i have a base map that my mechanic installed on the pfc for my modslist. the car although has always ran rich.
when it flooded last fall i was just coasting to a stop, the engine died and would not restart. so i towed it home and it has sat ever since....thx in advance for any advice

hey sorry smitter, i was just directing that question to you, not anyone else, but thanks for the info...

Did you pump the gas out of the engine?

When I flooded mine, due to bigger injectors and an untuned PFC, I had to run my starter in bursts off and on for about an hour with the injectors out and the relay pulled before it stopped smelling like gas comind out of the engine. Once I got Steve Kan to put a base map on it, it started right up. When we put it on the dyno, the first pull blew out the biggest cloud of black smoke I've ever seen. Once it coughed that up, it never did it again.

My advice is to pump out all the gas if you haven't already done that. Then get it tuned properly, not just a base map, you've probably got a lot of gunk in the engine. I would also guess that you just re-flooded your engine so you might want to start the procedure over again. If you can't get it tuned, put the stock base map back on it, start it up, let it warm up then take it out. Get on a straight stretch of road and WOT to redline. Aside from it being fun, it will help blast some of that crap out of the engine. I would do that a few times in second gear or so, don't lug the engine. Hope that helps, seriously, I've had the same problem before.

By the way, it may also be your O2 sensor reading lean, that would prompt the PFC to add more fuel and flood the engine. You really should get it tuned.


What's your injector duty and lag set to? What are your mods. If you're running too rich, they're not right.

Heres my mod list....injector duty is set to 100 percent....unsure of the lag (not a real wizard with the pfc by any means)
i took the car out and did some WOT runs in 2nd, 3rd and 4th gear...it ran great...12's for afrs under full boost ....idle is still high... about 2100 rpm....with afrs at mid 11s..........still though when i got her home.......i let the turbo timer do its thing the tried to start it again.........it wouldnt go

Smitter

well its been 3 hrs since i shut it off after the cruise....car still does not wanna start....got anything else for me 2 try?

check your pfc options... meaning check the idle set tab. this seems really wierd, is this the first time you started the car as is? the linkage or the the pfc can only imo make the car idle this hight!!!

I agree, it's either your throttle cable being too tight or your PFC. I would take the cable loose on both the cruise control and the normal cable and reinstall them but make sure there's some slack in the line so you can eliminate that as a possible problem. My cruise control stuck on my one time and it was because it wasn't seated properly in the actual cruise control module. I popped it back in place and the idle smoothed right out. Now it sits right at 1000 rpm. I would definately look there first.

Next, you really need to get that PFC tuned by a pro. If you can get to a Steve Kan tune session, I highly recommend it, he's seriously the man.

By the way, I would stop using that WD-40 trick if it were my engine. Have you seen what that stuff can do to moving parts. It gets sticky and everything stick to it. I've never sprayed it into an engine but I would use something designed to be sprayed into an engine like starting fluid. I still think that your problem is that your PFC is not tuned right though. You should reset it to the factory base map IMO.

I still haven't seen any post about you pulling the plugs yet. You should definately do that. If they're wet, that would explain why the car won't start without help. Also, when you turn the car off, rev the engine up and when you turn the key off, floor the gas and keeep it floored until the car turns off, that will keep it from flooding again.
