Fuel Injectors stuck open!?
1988 Mazda RX-7 Non-turbo: 13b rotary, 5-speed
Engine loads up, now that I've replaced the FOULED spark plugs that were only about 3 months old, if i keep my foot in the gas before i turn the key and then dies as soon as i let off the gas now. Any help on primary fuel injectors and secondary fuel injectors. Any past experiences or knowledge about injectors sticking open or injector malfunctions. Flooding engine. Thank You in advance.

If the fuel injectors are stuck open, there should be fuel dripping out your tailpipe before long. They flow a LOT of fuel.
I don't quite understand your post with regards to what it does/doesn't do. You shouldn't need to use the gas pedal at all to start the car.

cont..
engine will not turn over unless my foot's in the gas. i smell gas profusely if i try to start it without pushin the gas but it doesnt start makes a noise like its turnin but nothin happens. havent noticed gas coming out the tailpipe. could it be the fuel pump??? the car started fine one day, drove it about 50 ft and shut it off. wouldnt start after that. it was just all of a sudden. but, if i keep my foot in the gas, the car will start now that ive replaced the plugs and formed the seals by spraying trans fluid in the intake. but i still cant figure whats wrong with it. plz help.

There's just tooooooooooooo many things it can be. Low compression/slightly leaking fuel injectors and the list goes on.
Is this condition an all the time thing? Or just in the morning when the engine is cold? Or does it start good in the morning but after the car warms up and has been driven and then shut off, does not start unless you put the pedal to the floor and then it starts?

no, its always started at a high rpm (3500-3000) on cold days and when it hasnt been driven in 24hours but settles to an idle of about 1200 and driven fine.
but all of a sudden it floods the plugs in gasoline and it wont start. sounds like there no compression. i replaced the plugs and it will only start when i push in the gas and shuts off as soon as i take my foot off the pedal.

All of a sudden floods and dies while driving?? Or all of a sudden floods and dies when idling? Curious.
EDIT: You might try getting the injectors cleaned, that seems to be a favorite around here. I think there's something else wrong. You might pull the lower sparkplugs and do a poor mans compression check. Have someone crank the starter over while you put a finger over one empty sparkplug hole and then the other. The pressure should be trying to shove your finger off the sparkplug hole. The front rotor hole should feel much like the rear rotor hole when the engine is being cranked over.
It could be a apex seal let go and your starting on only one rotor. The engine won't run very well on one rotor much less idle.

floods before it gets a chance to idle. only runs when my foot's in it. the mechanic here seems to be focused on the injectors. what are ways to test both sets of fuel injectors with out tearin it apart?
