Today I went for a quick spin out in the woods.Anyway I was on this really narrow trail and I had to turn around.But there wasn't room to turn around so I had to back down a little bit until I could turn into a muddy/watery field.I went into the water backwards(up to the hub on the tires).Anyway The motor stalled because the fuel pump unplugged itself.After I figured that out it fired right up.But know the CEL stays lit all the time.What could the ECU be fuzzing about?Hopefully the problem doesnt involve connecting the black connectors,because I only know where one is(EJ wiring into EA car...)Thanks in advance.engine is 1990 Ej22,same computer.

Did you try resetting the computer - remove the negative battery terminal for 30 mins - ?

 

If the light came on immediately after it came unplugged, I'd try it. That EA doesn't have a rear O2 sensor, does it? It would cause a CEL if it 'got confused' when wet.

Good luck

my o2 sensor for the'22 is not even connected because I don't have a Y pipe that I can weld the bung to.It will happen monday.But I suppose I can disconnect the battery and see if it does it anymore.
