Running rich, high idle
 

Depending on your series, DO NOT TOUCH THE PEDAL WHILE CRANKING, this pops the tps out and makes the computer dump more fuel

If you have s4 pull the egi fuse again and deflood it again

If you have s5, just put the pedal all the way to the floor and crank it, s5 has a switch that while starting with the pedal down all the way cuts off the injectors

After you let it run again for awhile, shut if off, pull the egi fuse and compression test it, your motor may be getting tired

If your compression test comes back ok, replace the water thermoswitch thats on the back of the water pump, they can fail and make the computer think the engine is cold, when its not, and cold engines take more fuel to start than a hot engine

If this still doesn't fix it, get your injectors rebuilt, if they are original they are probably leaking

My money is on the thermoswitch though

If you are having high idle conditions more then likely you have one or more vacuum leaks. You can try turning the idle screw down "clockwise" If you can't turn it down enough you have a vacuum leak. Need to check for leaks. There are lots of threads on how to do this. Type rx7club vacuum leak into google or something similar. As far as it not starting after you got it started the first time this is pretty common as well. Check rx7club hot starts for clues on what to check for and fixes. I myself installed a fuel cut switch. I provided a link below. Or you can spend hours and lots of money trying other things that could be it and then later on spend the $5 on the switch that works everytime. Some call this a bandaid by the way. I no longer need to use it mostly as I have a aftermarket ECU that has lots of options and never had to worry about leaky injectors and all that stuff.

Rotary Resurrection home of the budget rebuild.

no, honestly it sounds like a loose battery terminal that you bumped while taking the fuse out

alternator has nothing to do with starting, just getting it ready to start next time
