I have a flooding problem every time I shut the car off. When I finally get it started it runs fine until I shut it off again. I don't know much about these motors, so any ideas would be helpful. The only thing I can think of is maybe a stuck injector...Thanks :(

you dont touch the gas pedal before you go to start it,do you?

cause if you do it will flood every time (at least mine does).

Mine does that too.......i klnow mine is mis-firing sometimes so im gonna adjust the timing..........

the fuel inj.s leak because the pressure from the fuel pump doesn't bleed off after the engine is shut off...after a while the inj's get old and drip because of all the pressure behind them.

either you need a "bleed-off valve" or

some way to cut out the fuel pump while killing or starting the engine



there's a few ways to do one of these things...or

replace the fuel injectors

Why would you touch the gas pedal to start the car anyhow? although they say if you floor the pedal then start it it wont flood, never tried it yet. If you are flooding everytime, there is something wrong though, maybe a leaky injector, low compression, also try a battery with more cranking amps.

only on 89-91 cars can you hold the accelerator to the floor to deflood minor flooding. if you flood it real bad you have to do the fuse trick. on 86-88 the TPS is not full range so don't touch the pedal or you will only flood it more! if nothing else crank with the egi fuse removed then reinstall and it should start right up https://www.nopistons.com/forums/pub...IR#>/smile.png

Or install my custom switch so you dont have to pull fuses anymore, and it deters theft.

a can of carb cleaner and blowing out with compressed air helps out. https://www.nopistons.com/forums/pub...R#>/mellow.png

i have an 89 and 93 . the only time i had to pull the fuse was the day i got it. the guy flooded it so bad it was spraying fuel out the side of the engine for about 10mins of cranking. i had a small flooding problem that went away the more i drove it. i love the full range TPS no more fuse pulling https://www.nopistons.com/forums/pub...#>/biggrin.png

seems like it helps to warm engine up everytime you crank it too. dont crank it for a short period on a cold winter day.

A reply from the owner of an 88RX7. Where do I get this full position TPS.

and who has the custom shut off switch to eliminate pulling the EGI fuse

to solve flooding? I have used the Bleed-off valve from Mazdatrix, and it seemed to work but did not completely resolve the excess cranking

needed to start the engine. I have also, pulled my injectors and had them

cleaned and rebuilt to specification. It is far cheaper than buying new ones.

Go to the salvage yard and pull some out of the same type engine you

have, I got 4 for sixty bucks. you can look on the web at www. fuelinjectors.com, I used EPI at 1-800-893-2260, cost $105.00, far cheaper than new or even store bought rebuilds. They will inspect, test for leaks,

rebuild, and flow test, and provide documentation showing the rebuild to

be in compliance w/ mfg specs.



Despite doing all I have done this thing is still hard to start after it sits for a day, once started it runs fine. Can anyone help me with this problem?

To the right of the steering column under the dash is a plug with about 10 wires or so in it, I believe one side of it is yellow, at least it is on my cars. In that plug is 2 blue wires, snip either one running it to a on/off switch, then back to the blue wire you snipped, when your car gives you any sign of flooding, switch it to off, then when the car starts, switch it on right away. Or you can do it the complex and mindless way of running a switch from the fuel pump. My way means you run about 6" of wire and you will be done in about 5 minutes time ( depending where you want to mount the switch )

in my 88gxl i put a fuel cut off switch right next to the security switch in the center console, fits in there pretty good to plus its kinda of like an anti theft device if u think about it

Its a 1988, on mine the plug as like 6-8 wires ( I looked under there today ), and mine has only one blue wire, but thats the wire you got to run the swith from.

I put the switch on one of the blue wires, and cranked the engine, did not smell gas as before. Turned switch on , cranked engine, no start, battery weak, been sitting 2 weeks. Hooked up jumpers cranked engine, and she

fired rihgt up. No smoke first few minutes, then some white smoke, but not as much as before, due to less cranking. What is the connection that the

yellow/white plug fits into, some sort of relay? Can the same thing be done by putting the switch on the green/black wire coming from the bottom

of the EGI inj., fuse in the fuse panel under the hood? While the car was idling I turned the switch off, but the engine did not shut down, doesn't

the switch turn the injectores on/off?

Listen, when the car wont start, you hit that switch, the car will no longer flood itself, it will however start, then you flip it back on, otherwise it will stall out. These cars DO NOT like weak batteries either, get yourself a good strong battery, I always say a Sears Die Hard Gold. I never tried hitting the switch while the car was running, why bother? And you flip the switch on AFTER the car starts, even if you flooded it a tiny bit, there will be enough gas to get the car going, you dont crank it then just hit the switch back to on when you feel like it, it wont work that way.
