Need Help Please!
So i have a problem with my 1987 rx7 turbo II. I was driving it hard one day around grabbing applications. Than i shut my car off to go recieve another application for work. I come back out and the car doesn't want to start up. I was assuming i have engine problems or something but turned out it wasn't. I got helped and jumped started it and it started right up. So today i wake up drive around in the car and it is perfectly FINE like the way it normaly is. After 4 hours or so after dropping off my girlfriend off home on the way to my home the car starts to shut off as i was driving. The car wasn't responding to my throttle was gasing but the engine was not reving than it travels up the street some more and finaly dies out. For sure the battery is one of the problems but i dont know the other problems. So my friend comes and let me use his battery from his 7 and the start is strong like it usually is but the car will not start up. Is it the starter or spark plug by any chance? While tryna start the car up with my frineds battery it cranks but wont start up. PLEASE HELP in DESPERATE NEEDS!! THANK YOU EVERY BODY IN ADVANCE. AND heres a pretty recent video of me starting my car.

"My car doesn't start
Remember when starting a fuel injected car you should never pump or press the accellerator pedal, but if it won't start it is probably flooded, Hold the accelerator pedal all the way down while cranking, do not pump the pedal. If it still doesn't start after a few tries, Then remove the EGI fuse and crank a couple more times, then re-install the fuse and try starting again. If then the car still fails to start it then you need to remove and clean the spark plugs, put in a teaspoon of ATF into the lower sparkplug holes, re-install the spark plugs and try again."
My older FC would flood out as it was dying (battery going very low) when the alternator was failing....

ONE MORE THING!!! Before it actualy DIED. THE CAR STARTED UP AND STAYED ON FOR 20 seconds than DIES out after that. Than after that problem the battery went low on me and the car had a really weak start than friend with a 7 brought his batter over. Louder and STRONGER START crank but would not START UP.

still sounds like you flooded it, once its started and gets to idle speed put your foot on the gas and keep it running.
Once these things are flooded real bad it can be real hard to get them to start.
If this doesn't work then start checking the other basics (spark, fuel,, fuses)

DO NOT PUT ATF IN THE ENGINE! ATF destroys carbon molecules! It will eat away the seals and your motor will eventually fail.
Exhaust leak will no way be the cause. The car is flooded. Flooding occurs when there is too much gasoline in the combustion area. You know that gasoline vapours are flammable right? It's not the liquid. Why do you think they submerge electric fuel pumps in the gas tank? Basically the spark plugs can't ignite the gas because it hasn't atomized (mixed) well enough during the intake cycle. (If its atomized at all, it might be a bad leak)
1. Pull EGI fuse (S5) or Pull EGI Comp and EGI Inj (S4). Pull the leading plugs and put a couple rags over the holes. Crank the engine, the rotor will pump the gas out of the open plug holes.
2. Put in motor oil to absorbe the gas...it does the same thing as ATF but it doesn't destroy your seals.
3. If its not flooded too bad, floor it and crank.
Depending on the milage of your motor I'd say you probably have leaky injectors its possible I might be wrong..but depending on the milage of your motor thats what I think it is. You might want to wire up a fuel cut off switch to disable your fuel pump and purge the lines when you want to shut the car off...basically just flip the switch and wait till it dies. Then your lines will be empty.
Yes the battery will discharge from continuous cranking...thats because the alternator hasn't had the chance to run and recharge the battery yet. Thats why you don't crank the **** out of it until the battery dies...just charge it, it'll be fine.
