Method 2: Step on it!
Although somewhat counterintuitive, the RX-7's ECU (Engine Control Unit) includes a bit of logic which actually cuts fuel flow when the accelerator is depressed all the way down while the engine is being cranked. (This is definitely the case in 88.5 and greater versions of the ECU. It's not clear that this 'feature' exists in older cars, however I have been able to start my 1987 car using this method, however, to err on the side of conservatism, you may want to skip directly to Step 3 if you own an 86-88.5 car, as if this feature doesn't exist, you'll end up flooding the car worse!). However, if this doesn't work, you'll then want to try...

 

like you said... MUSTANG... NOT RX-7... Mustang ECUs are different than RX-7s ECU and guess what... they probably manage the engine differently too!

yes... you cant even spell my name correctly. and - there is NO vacuum inside the engine when the car is off. If you have a vacuum gauge, it will read 0 when the car is off. Opening the throttle when the car is off will still show 0. thus, opening the throttle does NOTHING

you just contridated yourself. I said flooring it will cut fuel, and if it is not floored - i.e. around 70%, it will still give fuel. And remember how i said S4 doesnt have this feature?

i did... 70% is NOT WOT. ECU will still give gas on a S5. 70% is an EXAMPLE of NOT WOT....

 

So, and this would be really retarded if you were, so I'm asking... were you trying to explain that pumping the gas would yield essentially open throttle plate position, but still add fuel to the motor as a means of helping get all the fuel out of the motor? I'm pretty sure there were no arguments for you to be refuting by saying that 70% does not equal 100% (NO ****), and that anything less than 100% will not cut fuel (already stated way earlier in thread). What the hell were you trying to say?

 

My car used to flood bad before it died. I wasn't even sure what it was. But I'd be driving it and it would be fine. Shut it off and I couldn't turn it back on for about 7 hours. The only way I could start it within the first 10 minutes of it being shut off was to press the gas pedal all the way down until it started. I'm not saying thats what should be done, but thats all I could do. Eventually I tried starting it up using my gas pedal all the way down technique and coolant started blowing out into the overflow tank and I have ZERO coolant in the engine. Hooray! Time for rebuild!

 

aww damn man, thanks . Another thing I wanted to note to make sure that everyone can be as pissed as they can when they get back. If you press the gas the whole way down, and then crank... nothing happens before you start cranking, and no fuel is delivered. If you start cranking and then put your foot on the floor you have to (unless you can break laws of physics) pass through the full range of throttle before getting to WOT thereby putting at least some more gas in the engine. :P

 

learn to read and reread what i wrote.

 

That is correct. The Injectors Open with guess what, Electricity! Im lost on who is arguing here...I know Slpin is slpin Ford Mustang ECU's from the PONIES are race car ECU's they would work great on a Rx-7 if you could properly wire one except only would work on a 3 rotor due to being a different setup then a 13b which is like a 6 cylinder
The Rx-7 if its flooded, opening the butterfly may allow any vapors to exit the intake instead of the exhaust. as well Rotories are known for being able to run any kind of fuel almost so its ok to OVER FLOOD YOUR RIDE, there is no such thing, the only thing that happens is your plugs get WET!

 

O2 sensor too gets dirty and it doesnt hurt to change them when you can

 

Ah, man you guys... a lot of pruning needed to be done here because super thinks a RX-7 is a mustang.

If Super read the owners manual to start with he would have understood the unflooding proceedure for all rotary engines.

You hold the throttle all the way open (without pumping, tapping, or playing with yourself in anyway) so that the throttle plates open all the way allowing the maximum amount of air through the engine.

This is regardless of series. Remember the Rotary engine was designed originally to be a water pump. You can not have too much fluid/fuel in it. But to run it needs air.

Now the S5 and later versions (including the Reni in the 8), do also monitor the second position of the TPS, and when the ECU "see's" an WOT position, cut fuel if the engine is not running.

And the O2 garbage in Supers last post shows he needs to go back to autoshop 101, as O2 sensors don't get dirty. They get old from the chemical catalyst process. Any dirt is blown off by the 800+ temps at the exhaust coming out of a rotary.

So, now that the question has been answered (and beaten to death by people that think EFI systems work like Carb'd piston engines). If there is any reason to keep this thread going, the starter of the thread can PM any 2nd gen moderator and they will re-open it.

Otherwise, this thread is closed
