buddy of mine has an 86 rx7 car ran great yesterday he got in it this morning and the car just billowed white smoke everywhere but did run he came over drove me down the street to show what it was doing and it was very underpowered shooting flames backfiring just running like **** he left here went home and when he went to leave his house the car wouldnt start back up checked spark all 4 wires have spark did not pull all plugs but the one he did was black its getting fuel so i unhooked the tps thinking that might have something to do with it but nothing happened i unplugged the fuel pump cranked it for a few seconds and it cranked over and tryed to start then stopped i plugged the fuel pump back in then it bumped over again then nothin unplugged same thing happened again so i believe the car is flooding have not checked compression yet but i think an injector may be sticking open and just flooding the motor please any help would be appreciated ive searched the forum but couldnt find anything thanks

 

Hard to read, but have you tried to deflood. If you pull rail you'll see a stuck open injector after activating pump. I would definately try a compression test also.
