Turns over but won't start?
Ok was just going to take my rx7 out fir a spin but for some odd reason it won't start. It turns over with ease but doesnt even try to start. I just drove it multiple times this morning without issues. First thing that came tomind was either the fuel pump or the fuel filter is clogged and or the ignition system gave out? All ideas on what it could be would be great. Thanks

Crank w/no start
Well, I cant say for sure w/o more info, but if it was running good earlier w/ no signs of trouble
then I would say treat it like a 2 stroke motorcycle and try to push/pull start it with key in
run position. That is after you are sure you have fuel/air/spark all at about the right time.
Remember, if the car thinks that the motor is loaded up it will not allow it to start when using
crank position, but will not know anything except to start with ignition on and a little bit of
push. Oh yeah, or pull.
My first message man so let me know the outcome.

Ok did a small check this morning on the fuel pump. For the 2nd gen rx7's is it normal to not hear the fuel pump whirring for a few seconds when the key is in the on position "not started" or is that how its suppose to be for the 2nd gens. Im going to check for spark when I get off work and if thats not the problem remove and check the fuel pump.

Did the overall check this morning. Fule pump is running strong and the connections to the pump are good. But there is no sparking at the plugs. Ideas?

Did you get running???
Hey Takedown
Is your 7 an automatic? The reason I ask, and of course I could be wrong is that
one day I pulled my car out of the garage just to wash it in the driveway only to
find out it would not start back up when I was done. It was time to troubleshoot
the problem, something that I am usually pretty good at. Ok, the car was running
perfect when I parked it in the garage, was ok when I pulled it out to wash it, then would not start. The car turned over just like normal and seemed like it should start but it would not. Troubleshot coils and plug wires which checked ok,
however I was not getting any spark. Plugs are ok by the way. After days of
trying to figure this out we decided to try and pull start the car with the key in
the ON position. Started right up and was ok. I have had to pull start the car
a few times since, but only if the car is started for a very short time when cold.
I am convinced that if the car thinks the engine is loaded up with fuel (like flooded)
it will not fire using the CRANK position. Some automatics can be pull/push started
under 5mph but Im not sure about RX7's.

check out Deflooding.
some Quirks about the Rx7 is that it will flood out if you just start it drive it a couple hundred feet and Turn it off..it likes to flood out.
Try a site called rotaryresurrection.com ..tap on teh Sec gen Car Picture, then Hit TECH and it lists some info on Deflooding..Good site to read.

Pull start it man
Have you tried pull starting it? Am I missing something as to why you maybe dont
want to try this? RX7's will load up (flood out) when started cold and not run for
very long. If this happens you can however pull start the car. One way to prevent
this problem is this. When the car is started cold for a short time, run the engine at 3000rpm for about 10 seconds then shut off car. If that still doesnt work then
I would suggest 10-20 seconds at 3000rpm, then when shutting off ignition floor
gas pedal till engine stops running.

check the distributor for cracks and moisture inside. Check the ignitors attached to the distributor - check their resistance using a DMM; I believe they are supposed to have 1000-something ohms at the two terminals and zero ohms when you switch terminals. Check your connections at the coils and check the coils themselves.

when this happens the main things that cause a car to turn over but not get fire are either spark or fuel. so everyone has hit the nail on the head check every possible part to the fuel system or ignition. I have found that haynes or chilton books from local auto parts stores have troubleshooting sections in the back invest in one they are worth it.

Pull start it dude
Have you tried to pull start it yet? The car may acturally be ok. When this happens to me the car just wont fire with the key in crank. It does not say anything about this in my service manual, but I have had to do it several times over the years. Oh yeah, I strongly reccommend you buy a Mazda Factory Service Manual. This will have to be ordered from Japan probably but it puts any Haynes
or Chilton book to shame, to say the least. Mine came as loose sheets, about 1200 pages, and I put them in clear sheet protectors and those in are 3-ring binders. You cant go wrong with factory manual.
