After reading this:
http://www.rx7.com/tech/unflood-fc.html
Is it possible my car is actually not flooding? It says rx7's will not unflood themselves. My car only 'floods' when the engine is warm(95% of the time anyways). If I wait until morning when the engine is nice and cool, it will start fine. Anyone know anything about this?

And also at that site they say "Once fuse is pulled and left out, get back inside vehicle. Hold accelerator pedal to the floor and crank for 15~20 seconds. Vehicle will not start during this procedure. Remember, it is key to this procedure that you hold the accelerator down and crank the engine at the same time."

I don't think I ever press the gas when I do this trick.

 

Either do one of two things. Either make yourself a fuel cut switch or unplug the fuel pumps plug and start the car.

The advantage of both: You have SPARK when trying to unflood the car, whereas using the fuse thing, you have no spark. All that method is doing is shoving excess/trapped fuel out into the exaust. IF you have spark, plus shoving the excess fuel out the exaust, while holding the pedal to the metal, you have an advantage in the sparkplugs firing and helping out burning off the excess fuel and starting the engine.

Both methods, fuse pulling and or fuel cut switch turn off the fuel pump keeping additional gas from being injected. But with the fuel cut sw you can flip the pump on just as the car/engine starts and walla, drive the thing off into the sunset

So you don't know if its flooded or not? Ok. Next time pull the fuel pumps plug off and start the car. If it revs for a moment......it was indeed flooded. I don't give instructions for making fuel cut switches.

 

To find out for sure if your engine is flooded is to pull the plugs and see if they are fuel wet.

Rx7's will flood themselves due to bad/leaky injectors.

You dont have to press the gas pedal. Well, I dont.

Fuel cut off switch
The "band aid" cure for cars which flood consistently is to install a toggle switch which will control the fuel pump. Note that the only cures for consistent flooding are cleaning/rebuilding injectors, rebuilding the engine, or finishing rebuild breakin. I like to install my cutoff switch right behind the keyhole in the lower column surround, but anywhere within easy reach will work. I use a toggle switch available at radio shack for about 2 dollar, called a rocker switch. IT is solid black, very slimline(maximum protrusion 1/8") and fits perfectly. You can use any toggle switch however.
1) Obtain the following: 2 prong, 2 position toggle switch, at least 2 feet length of 16-14 gauge wire, 2 female speaker terminal connectors(quick connect), 2 wire taps(vampire taps) and wire crimpers/strippers. Vampire taps join one wire beside another, when a metal strip gets pushed down connecting the 2 wires. A clean way to connect 2 wires.
2) Remove column cover and install the toggle switch in its position(or wherever else you want).
3) Locate the fuelpump relay under the dash. Located between the radio and the steering column, it is a black relay with a white, 5 wire plug.
4) Cut the fuelpump control wire: of the 5 wire plug, cut the middle wire of the 5.
5) Run wires from the toggle switch to each of the ends you just cut and connect them all. Which wire goes to which end does not matter, there is no polarity here, only continuity.
6) Put everything back together. Your switch is now installed.
7) To operate it, figure out which way is on and which is off. I like to orient off downward.
8) With the car running, flip the switch off and allow the engine to stall. Remove your key, and leave the switch off. The fuelpump cuts off, and the engine drinks all the fuel in the line until it is gone, which means there is none left to flood the engine later.
9) When restarting, insert key, crank car, and flip on switch WHILE cranking. The fuelpump will come to life, shoot fuel into the engine, and it will start normally. Flooring the gas is sometimes helpful but not required.
10) Some cars may even start for a second before the switch is flipped, from residual fuel in the rail. In this case, the procedure should be to insert key and turn, car will start, then flip switch on immediately to keep it running.

 

Series five unlike the series four have a built in method for unflooding. They tell them to hold the pedal to the floor and crank the engine til it starts. Yeah, I know he has a series four.

Series four have no such procedure. Low compression will cause one to flood easily. Also there is the known problem with starting the car up and say just moving it to the front of the house, then going back later to move it and the car not starting. That was/is a ECU problem that you can't fix. It's a built in fault.

Go to the RX8 site, and what do we see???? Flooding problems. Geeeez.

I think even I could make a fuel cutoff switch following the instructions above.

 

Wow the more things change the more they stay the same... Thats pretty bad..

There is a glitch in the s4 ecu, that holds the injectors wide open for about 5 seconds... Every now and then my gx(n/a) will do it, It leaves a puddle of gas on the garage floor about 6 feet in diameter, and 1/4 deep, all from 5 seconds of cranking... Thats a ton of fuel, so all the injectors basically have to be locked open to deliver that, and in order for it to leak from where it does, the exhaust is totally full as well...When it starts, it changes the weather forcast.. compression is good on this motor and the car is in top tune....Max

 

Thanks for your input guys. I'm thinking about selling my car in the spring. I have put a lot of time/effort/money into it in the past year, but it seems something always wants to break or get worse. I should've kept my 86 GXL.....not one problem with it for almost 2 years.

 

damn, i hate that feeling. Well goodluck, maybe she'll be more keen to you next few months so you don't have those harsh feelings come spring.
