This is getting on my nerves. Car flooded again today. Only times it ever floods is after sitting for close to or over 10 hours and its very humid or rainy out.



I'm hoping its a sensor or something but I havent bothered looking at any of them yet. Anyone?

I've owned 2 86 RX's that would flood at times and this trick works for me. When you shut the car down rev it up to about 3500 as you turn off the key. Both my cars would flood at times but never since I've started using the rev shut down. Let me know if it works for you.

that and vacuum leaks, very small ones will make it act wierd like that

It has been a little low on vacuum lately. So its either that or low compression, weeeeeeee!

My FC always had the habit of doing it in the most worst places i could find. Always somewhere i would get made like a fool....gas station, out front of a place with chicks, etc. Never in the driveway or somewhere normal

Yeah, but did your car ever flood when you were in line at a automatic car wash and their were 20 cars behind you? talk about ******* embarassing https://www.nopistons.com/forums/pub..._DIR#>/sad.png https://www.nopistons.com/forums/pub..._DIR#>/sad.png I got the fuel t way and it has helped out. Why do we like these cars again??

OK, NOW it flooded after being shut off for only an hour and a half. Engine was still warm without a doubt. I'm completely confused on this one.

Yeah.. my car is flooding too.. wonder what it is.. i will try the 3500 rpm's and see if it works.. wonder if its the injectors or fuel pump? the pull the fuses works for me... to get it going but i get tired of poping the hood every time..if the car sits over night ...the next morning...walla it never misses and cranks right up

wiring in a switch on the fuel pump helps, shut off the fuel pump before you turn off the engine, let it exhaust the fuel in the lines right before you shut it off.



but this really only helps when you've got leaky injectors that flood the engine while it sits after shutting off.

A couple things, A your plugs could be fouled and it is just making it harder to start. Or your injectors could be leaky. Unless you have recently purchased new injectors or had them flowed tested, I would definately recommend getting them flow tested. Oh and you want a bad time for flooding. After I installed my Haltech I went to a 7 meet, the next day. We came back to our town and on the way back my running lights, and interior lights went out. Light switch went retarded, still had my driving lights though thank god. Anyway we get back to my town, and a friend of mine go out to do a little tuning, well we get to driving around, and I have by this time forgetton to put my flashers on. So I get on to a nice road, give it a couple runs then slow down, as I come to an intersection. I start to pull up to the intersection and see a cop behind me. So I'm like ditch the computer dude. We turn and the cop pulls me over. This is also the time when I don't have my power windows hooked up. So cop knocks on the door, I open it and start talking to him. He starts to be an ass, so I act even more civil, finally I give a little lip, and he checks my record, comes back with a warning. Yeah that's right bitch nothing on the record. Anyway after this the guys starts talking about how shitty my car is because I don't have the interior door on, and I don't have lights work, etc etc. And at this point, I am pissed because he is ditching my car. We exchange remarks, and I go to start the car. Well 15 seconds later when I have it started I look in my rear view mirror and can't even see the cops 10ft behind me because there is so much smoke. Literally 60ft high 40 wide. It was great. My buddy just started cracking up and could not stop.



- Hand

wanna hear one of the reasons i found out about why cars flood. ok other than rx-7s having major problems on there own you wouldnt want it to flood. now apparently there was a flaw in the switch for cold starting and if you dont let the car get up to normal operation temperature the car will save the file so when you go to start the computer up and turn the car over it still thinks your cold starting and will flood the engine to run rich trying to get the car up to n.o.t.. apparently when this happens to much you wanna clean the spark plugs and change the oil. other than that its a real problem though. you want to let the car get to normal operation temperature before you shut it off again and that way it wont keep flooding.



just some advice.



if your using a haltech adjust it to run lean and try and start the car.

i cant believe people still pop thier hoods to pull fuses when

the car floods, you dont even have to get out of

the driverseat when it happens.

Do enlighten us then https://www.nopistons.com/forums/pub...#>/biggrin.png



My seven is cold natured as **** and floods at the drop of a hat these days.

Yes, please enlighten us Rob x-7. If you are talking about just flooring the gas pedal, that only works in the S5 not the S4.



What other way is there for the S4 owner other than pulling a fuse?



With all this talk about cars flooding, I have been kinda wondering what has been happening with your cars?



Since my rebuild, my car has not flooded once. Not once. I maybe just lucky. I have other problems like possibly not being able to pass inspection and a loose connection on my wiring harness but the car has not flooded in a year (rebuilt last year). Maybe I am lucky. https://www.nopistons.com/forums/pub...1047683329.gif

I think Rob is pulling the harness off the fuel pump relay. its near the pedals on the steering column.

But i think if your always having this problem you should;



A: find the source of the problem



B: if you find its the injectors and you dont want to spend the cash, wire a switch to said pump relay.

my car doesnt flood.



I pull the harness by the steering wheel column, you can

also wire a switch to it, I have typed it about a bazillion

times so it should be easy to do. You can pull the harness and

crank the engine at the same time, its a 1 person operation

and then you can plug it back in when you like.



There was also a picture of the harness someplace as well.



and yes- if your car is always flooding then you should find the source

of the problem. My car sits alot, sometimes for months, so when I first

go to start it I pull the harness.

can you explain exactly what "pulling the harness" is



for the people who need the help

I guess im lucky, my car runs rich and can sit for weeks and not flood.



hot.



but it is nice to know some methods in the rare event that it does flood some time.



kevin.

to the right side of the steering column is a wiring harness, one side

of it is yellow I believe, there is like 6-8 wires or so in it, you unplug the harness

when you get a no start, crank the car over, usually there is enough

gas in the engine for it to start, once it does you plug the thing back in





once you know where the plug is you can use one hand for the key

and one for the harness.



if your getting the fast cranking like there is no compression you can

use this method as well.

well id just get the injectors checked if your to lazy to do anything lemme see if i can find the article on the engine and ill post it if i can find it

ok well i found this site it might help if you in the same kind of predicament if anyone wants to try this and tell me if it works for 86 and up please do cause i couldn't find the updated site but this could be the same problem your having https://www.nopistons.com/forums/pub...IR#>/bigok.gif

woops didnt post the site sorry http://www.rx7.com/tech/unflood-sa-carb.html





ok that should work https://www.nopistons.com/forums/pub...IR#>/wacko.png https://www.nopistons.com/forums/pub...IR#>/wacko.png https://www.nopistons.com/forums/pub...IR#>/wacko.png https://www.nopistons.com/forums/pub...IR#>/wacko.png https://www.nopistons.com/forums/pub...1047683329.gif https://www.nopistons.com/forums/pub...1047683329.gif https://www.nopistons.com/forums/pub...1047683329.gif

Im having the same issue. i know flooding is common but from what i hear the longer it sits thee the longer it would give my fuel injectors time to leak onto the rotor, but to me the opposite is happening. If i park it the longer it sits the better off I am. Everytime i walk outside in the morning to start it she gives me no problems, but sure enough if i drove her an hour ago she might flood on me, and it also seems to be more likely to happen the colder or the more humid it is. One lil trick i have learned (and i have an s4) is to floor it for a few seconds before cranking it and then cranking her over and then for some reason i have a little bit more momentum heading into a start where she almost floods out but starts anyhow. Any reasoning for this?
