So I flooded my RX-7 the good old fashioned, kick yourself afterward for the idiocy of it way. Since then I've tried everything short of ATF. First I just tried cranking it a bit with the egi fuse out, then when that failed I did the same and cleaned the plugs. They look good, and I know they were changed just before I bought the thing, so very recently. I've removed and cleaned all the plugs a couple times now, tried to move all the gas out of there, and tried starting it a couple times to no avail. It's now to the point where I need to get some oil in there to lube it up and get some compression, but honestly, how long should this take? I'm fearing I'm doing something wrong, though I've read over the unflooding procedure plenty of times. Either that or there's some other issue. Some input would be appreciated since I'd rather not buy a battery charger just for this one incident.

are you getting spark?

Easiest way to unflood an engine like that is to take out the spark plugs remove the ignition fuse and crank it over for twenty seconds. It'll get rid of all the fuel in there, then put the plugs and fuse back in and start normally.

That has always worked for me as well.

Probably did it 4 or 5 times, no dice.



I'm leaning towards not getting spark but I have no idea why that would be. The plugs seem fine, they had gas on them when I pulled them out, but a bit of cleaning and they're dandy. The wires are aftermarket NGKs and everything worked fine before this flood incident. Perhaps just not enough juice left in the battery after all the cranking? It still turns the engine without issue though. Battery charge meter is still about about 12.5V on the dash too.

i like to clean the plugs off, and unplug the fuel pump relay, its under the dash to the right of the steering column.



with no fuel pump, you just crank until it starts. removing the fuse disables the ecu, so you get no spark. spark is good.

Wouldn't this cause the engine to knock? No more fuel but spark and air sounds like a good way to break an apex seal.

nope it just cuts out and dies then plug it back in and start her up

That's another good way. If you want to check for spark disconnect the fuel pump relay like J9 said then pull your plugs out of the engine, keep them connected to the plug wires and lay them on the quarter panel. Don't touch them, have a friend turn the car over, and you can watch to see if you're getting spark.

Did just that and spark is nice and strong.
