Push starte it maybe the flywheel has a bad theeth and the starter is right on it. Pop the cluch to see if you could spin the engine. It could be a loose starter.

 

Its the starter or the flywheel

 

the problem is the starter as mentioned before if your car isnt turning over and the starter is just spinning that means there is something wrong with the solenoid try this...Get under the car and jumper the small blade on the solenoid its the one with the small black connector on it and the large wire on the solenoid the starter should spin and make sure the the car is in nuetral when you do this listen if you hear a loud click.

 

I will try this but i already said is a new starter and solenoid, what are the odds? Now could it be the flywheel??? Im about to buy a Crank Angle Sensor i found in eBay, any chance this could work? how difficult it is to install?

 

you dont need to buy a new crank angle sensor start with the stuff that you know that is the problem it doesnt matter if its a new starter or not the new starter could just be stuck.

 

has anyone visually confirmed outside the car that the serpentine belts are not spinning while your cranking it. the rotary is pretty smooth so if your engine is flooded and you lose compression bc of that it can make it seem like your engine isnt spinning at all when in fact it could be but just with very little resistance. i doubt that your engine is not cranking especially with a new starter. your engine might be flooded, pull one of your leading spark plugs out and check to see if its covered in gas. good luck.

 

I checked and the cerpentine belts are turning slowly, i look at a spark plug and it has a little bit of gas on it, but i think thats normal, or is it? How does the car get flooded tough and how do you fix that?

 

just give the car to me lol

 

first of all is your car an s5 or an s4 and how many miles on the engine?

second; realize that all that time you spent trying to start the car and cranking it only served to inject more fuel into the housings and causing all the compression aiding oil film to "wash" off and lose compression hence it will want to start that much less. keep in mind that s5's or 89-91 fc's do not inject fuel at all if the gas pedal is held to the floor while cranking as opposed to s4 fc's
search "deflooding"

third; no there isnt supposed to be fuel on your spark plugs
again search how to deflood

fourth; if your serpentine belts are spinning with the key held at the start position then your engine can be considered to be "turning over" or "cranking"
i suggest you charge your battery or jump it with another battery when you get everything deflooded, retimed, etc. as it will be weak when it is time to start it.

finally since the Crank Angle sensor (or the diagonally placed round stick with a black cap and two screws) was messed with i highly suggest that you look up on how to reset your ignition timing. look up "restabing cas" or "set ignition timing."

as always good luck and calm the **** down.

 

also the main cause to a randomly non starting engine is a flooded motor which is a very common occurrence with rotary motors this old. the easiest fix to that is to get at least your primary injectors cleaned professionally or install a fuel cut off switch.

 

Check ignition timing. Remove the CAS, line up the needle and the red mark on the eccentric shaft pulley, now take the CAS and line the indent on the gear with the little bump on the body of the CAS..make sure to drop it and make sure that none of those gets fucked up..your timing should be fairly good. Now, if that doesn't work...get a stethoscope and stick it on your injectors while someone is cranking to verify they're firing. IF that all doesn't do anything it may be flooded beyond belief, pull out the EGI fuse (S5) or both EGI Fuses (S4) and crank for awile, reinstall the fuses and try to start. You can also push start, use oil to absorb gas if flooded (never use ATF!).

 

so it is turning over...your confusing me anyway do the deflood you probably have that thing flooded till the point you have to take the plugs out...make sure you do that really good and while you have the plugs out make sure you are getting spark after you have done this get back to us.

 

should be able to find the sensor at mazdatrix.com

 

Thanks a lot guys, you hwere right, the problem was that the engine flooded! I didnt know about this since im new to rotaries but from what ive seen you cant turn on and off a rotary motor in quick succesion because the fuel is injected in the intake to the rotor, this fuel stays un-burned inside and the engine spins, while also loosing compression because of the loss of oil seal while it spins. I found this website: http://www.rx7.org/Robinette/notes_e...20Engine%20Fix

It has a lot of useful info.

Again, thanks a lot i think i learned a lot from this experience and fron this forum in such a short amount of time :p
