I own an 86 non-turbo I was having flooding problems real bad all I could do was the fuse pull thing to get it to start one time I had to be towed around the block to get it to jump . I replaced the fuel filter , Pressure Regulator , and I just replaced the injectors they are bigger ones though 880cc now . I am having a little trouble I also have an after market K&N air system kit on it . My problem now is it seems I have lost some power when I get in the 4 to 5 grand range I start boggin like not enough fuel so im lookin at a better fule pump 225 LPH and a bigger Fuel Pressure regulator . I just wanna know if anyone thinks that would help out with that problem or knows what else it could be and can this be a computer problem to ?
My e-mail is Toxindude@yahoo.com please let me know thnx

rocky99507: I have 2 red '87 RX7s. My wife hates both of 'em and all the extra parts I have. With the flooding problems, I always do 3 preliminary steps: 1) make sure that the floor mat is pushed back so that the clutch pedal can be pulled depressed, 2)have recent clean spark plugs installed, and 3)have recent spark plug wires. Now comes the tricky part and is 2 parts: 1) replace the thermo/thermal sensor on the lower corner of the radiator on the driver's side. Note, on my model, it is a two prong round plugs - some have different plugs. When buying this sensor, buy a wrench from the parts store and this will save some grief later on. 2) Whenever my car floods, an experienced mechanic recommends that you remove the air-cleaner filter assembly, which is held on by 3 bolts (I never reinstall these...just in case), disconnect the yellow plug underneath the air cleaner. The car will start right up and the exhaust smoke is a thicker black. The car will stop after a couple of seconds. You can now re-plug the yellow connector plug underneath the air cleaner, put the air cleaner back in place, lower the hood & your car will suddenly start when you start your car!!! Most "experienced" car mechanics don't know this. Try it & it works. The theory behind the thermo/thermal sensor on the radiator is that it sends a signal to the car's computer & the computer knows if the car is cold or hot and adjusts the fuel that way. One problem that I've had over the years, is that this sensor is intermittent, meaning that it works some of the times. Also by unplugging the yellow connector plug underneath the air cleaner, it bypasses a signal to the computer, thereby allowing you to start the car by burning the fuel that caused the over-flooding. This should help. Rock on!!! Rev on!!!

I am also having the same problem. When its cold it starts right up but evertime time I try to start it when its hot it will flood. Then I have to unplug the same switch and take out the top plugs and crank the hell out of it. One of my buddies fixed some other things on it and he said to try all the injectors to see if they were messing up. I havent got around to it yet, but if it is compression, whats that mean? And how do I fix that?

My 86 did this when I had a weak starter and leaking injectors... it just wouldn't crank over fast enough to catch. I replaced the starter, and had the injectors rebuilt, and she started with no problem after that.

The other thing it could be, sorry to say, is low compression. Have your compression tested (buy a $20 pepboy's gauge, holding down the valve and watching the pulses go by while a friend cranks) don't forget to pull the spark plug relay and fuel pump relay while you crank. Compare front to back rotor readings.

Last thing to try is the old ATF trick. Get about a 1/4 to 1/2 cup of ATF into each rotor chamber, then crank it over. Do it at night so your neighbors won't call the fire department on you... it will smoke like crazy.

I tried to start my car in the cold and it started and then died. It is an 86 RX7. It now sounds like it is turning over but not firing at all. Does this mean that it is flooded? Please help.

Sounds like low compression on all of yalls problems. My car did that when my coolant seal was going. It would flood alot, pretty much everytime id turn the car off it would "flood". your best bet is to get a compression test and see what your numbers are at you want 90+.

Are yall burning anything when you start? like coolant or exsessive amounts of oil.
