I have a 1988 Mazda Rx-7 non-turbo and not all the time but every now and then when i go to start it it cranks but wont start. Is the engine flooding or is it something else?

did you install the filter the correct way
sounds like the pump is not working properly
a faulty regulator will dump excess fuel

i believe 10w30 non syntetic since it use oil by design 41/2 but u need check every week cause some rotary enines use oil rapidly i like puolator oil filters best especially the pure one if u can get it

I use to run my own switch for the fuel pump. Leave the power off to the pump for about 10 mins. Then power it up then start engine. If this doesn't work use a little starting fluid. If that doesn't start the engine check to make sure you are getting spark to the plug. If you are check the compression.

I have a 2005 mazda rx 8. I went out to crank it up yesterday day and it would not fire. I had started up on Saturday just fine. What could be the problem?

do you put your foot on the accelerator while cranking ???
rotors flood easily so dont be too worried if everything checks out
- voltage to coil packs are correct
- coil pack resistance is correct
- autochokes not jammed shut
- plugs are the correct type
- ht leads are measuring under 20k ohms
- what size fuel injectors are fitted...standard? a/market? impedence higher or lower than original? is cc rating higher tahn factory??

Engine is flooded. Car must be taken to Mazda Dealer to have computer reset(flashed). I have a 2004 that needs this done about 3-5 times/year. Weird but true.

actually no it wouldnt immediately. As long as all your fuel and air lines are hooked up (i.e. vaccum) your fine! Because 1988 didnt have a programmed sync with it's computer to run with or without the turbo it has little affect. But, it will lag your power after you start sometimes it will shut off. But it does run without it. A turbo system is just a superman air induction system. Thats all.I have seen one drive without Turbo. Why would you need to run it without turbo anyways?
Hope this helps more than the other guy commenting.

8 what was that guy thinking has he ever even looked at a rotery moter before THERE ARE ONLY 4 SPARK PLUGS in any RX-7 turbo or not and NKG plugs have always worked best for me

maybe the front seal is bad
