What exactly makes rotaries flood?



I am dealing with this problem right now, and I have changed out the plugs. The plugs that were pulled out, were carboned over, and just nasty looking. There is only about 1000 miles on those plugs also. What is making the plugs doing this?



My car is really hesitating to start right now, it wants to start, keeps kicking over, but just does not want to stay started. Am I flooded?



Could it be something else, and I am not flooded? Fuel pump, fuel filter, not enough fuel or air being mixed in?



Other words....please help me, as this is my only means of transportation.

Leaking injectors, low compression.

I never thought about the injectors. Compression seemed fine, but I did not have any tester hooked up to it. I did it the ghetto way by taking out the trailing plugs and turning the engine over to check. 3 even pulses on the front and rear rotors.



Thanks Revvin

Resistance will build in the stock EFI system over years and years. Very minimal but it's there none the less. Add that to other old parts beginning to fail from old age.. Being a 16 or more year old car doesn't help.



Little things here and there contribute.

2 things:



the starting maps in the ecu are very rich, and they used a dual post coil for the leading. dual post coil is bad here because both leading plugs are on the same circuit, so if one leading plug is wet NEITHER will fire.



vacuum leaks, even small ones will cause flooding.



ive seen like 1 leaky injector

LOL. That is who I like to turn to. Smart people.



Ok, I have checked in the Haynes Manual about checking injectors, and it says to have the car started and warmed up, but as stated before, I can't even get the car to start. Is there any other way to check the injectors without having the car started?

This is really killing me right now, and I am not experienced with rotaries or cars for that matter. My father knows about fuel injection and carb's, but does not want to help me at all. Thankfully my neighbor is FD3BOOST and does help me out when needed, but does not have much experience with FCs.



Thanks fellas.

Put cod liver oil in it!



If you are having problems then pull the EGI fuse under the hood and crank the car over for a while.. Then plug it back in and it should fire..

Tryed that on the first day. Should it be the main EGI relay or the EGI Main fuse?



Off the wall question, could the car not start up because the fuse could be blown?
