Water in cylinder
 
My son has an RX7, 85. He let it run low on gas and had it parked on an incline. He put more gas in it, but now it will not start. REplaced the battery. Had it towed. They said that there is water in the cylinders!? It was working great until this time. Any suggestions? I did notice when we cranked it over that there was water coming out of the exhaust.

Go to a garage that knows what a rotary engine is for a start!!!

We have rotors, not pistons!



remove the spark plugs, and squirt in some easy-start liquid. Leave it a few hours, put the plugs back in, and give it another whirl!!!

It could possably be flooded, although i think this more common on an FC not a 1st gen..

Water in rotor cavity
 
Still nothing. It started before it sat up. It used to start right away. Ran low on gas, now nothing?!!

Drain ALL the old fuel out, and put some fesh stuff in. You might have a bit of water in the tank

What... "water in the cylinder".Guys there is something wrong with that statment...

There are no cylinders in a rotary

pull the plugs, disconect the coils, hold the throttle wide open(if it is fuel injected you will have to unplug the injectors) turn the motor over eight or ten times, put it all back together and start it(be very careful not to light the fuel mixture on fire as it could explode)

If that doesn't work you could do a radiator pressure leak down test. A lot of condinsation builds up in the exhaust and is confused with water leaking from the engine...You should also be using antifreeze in the cooling system, meaning if there is water coming out of the exhaust from the engine it should also contain coolant.

sounds more like a bad fuel pump to me.

Do the trans fluid in the carby trick:
1)Remove the spark plugs.
2)Disconnect the "leading" and "trailing" coil wires (the wires which look like spark plug wires).
3)Pour approximately 1/4 cup of automatic transmission fluid into the carb WHILE someone else is cranking the engine. Note: Carb has 4 holes, the ATF gets poured into the 2 holes located within the carb but closest to drivers side front tire.
4)Continue to crank the engine over till very little "mist" comes out of the spark plug holes.
5)Reinstall sparkplugs, reconnect coil wires, start car.
THE END
Sorry to sound so basic, But this is basic, Carby has holes???LOL@self.
