22re flooding on warm start
my 22re just started doing this, on warm/hot start like if iv been driving it hard and then turn it off and back on in less than 5 mins if it sits for 20-30 mins it starts just fine. but otherwise it floods, then i have to pull the efi fuse crank it over with my food to the floor and it will fire run for a second then die out plug the fuse back in and it will normaly start right up, somtimes i have to do this two or 3 times before i get it running, this only started yesterday. 89 22re

had a simular problem with mine. started fine when cold, ran and drove fine. when you would turn it off and try and start it when it was warm, it would start just like it was flooded (not as bad as yours). it was the head gasket leaking coolant into the cylinders. you could smell it when you first started it. my fix, I rebuilt the whole engine.

i have an fresh rebuild, and you can smell gas coming out the tail pipe if you keep trying to crank it over after its flooded. i'm thinking it might be cold start injector related, or maybe an bad coolant temp sensor. but looking for some advice before i start throwing money at it.

Use a mulitmeter and check for voltage on the cold start injector connector when you're cranking the engine AND the engine is warm. If you have voltage on the cold start injector connector when doing this, the cold start injector time switch is likely malfunctioning.
