No crank, No click, Car runs
Hi all, my FD won't crank, I went through forums and tried most of advice and I'm about to run out of ideas here. The car never had starting issue, and yesterday after a long drive, I turn the car off for gas stop, and it wont crank again when I turn it on. No crank, no click. Car is throwing CEL code 2, the crank position sensor NE, but I'm not sure how to investigate further at this point.
Things I tried :
- jump the factory immobilizer
- jump clutch switch
- Tested battery/Starter (good)
- Tested voltage at starter during ON and crank (12 volt)
- Jumped starter on the car with harness connected ( fuel pump comes on, no crank)
- Jumped starter off the car ( solenoid kicks and starter cranks)
- Push start the car (engine turned on right away)
Spec :
1993 Rx7
- stock harness
- stock engine
- stock rats nest
The car is mostly stock besides racing beat down pipe and cat back
Any input is appreciated

Did some more investigation today, and I found that the voltage from ignition is only 8 volt when cranking. So I looked up the petit starter booster diagram and made myself a booster based on it. Pretty simple, but the starter still won't crank.
I applied 12volt at the ignition, and the starter turned. So at this point, I'm positive the no crank issue is somehow related to the iginition.

Had that happen to my corolla when the alternators charging wire... Decided to get hot and melt the plastic it sat on and short out. Started to lose different thing. I first lost my dash lights then I lost my headlights then I lost my stereo then I . st pulled over as I knew something was really wrong. After I shut it off nothing worked no crank no click no Nada lol. Granted my issue went south pretty fast, but the main engine fuse controls quite a bit for providing power.

Not sure if you solved this issue yet, but I had the same exact thing happen to me and pretty much took the same initial steps. While I was jumping the clutch switch, that is the one aft of the clutch that allows the plunger to extend out from the switch, I found some pieces of hard rubber/plastic on the floormat.
Turns out this was the insert that resides in the circular aperture of the arm coming off the clutch pedal assembly and depresses the plunger of the clutch switch that's located forward of the clutch coming off the firewall.
That switch disables the starter when the clutch is not depressed, which is the safety feature requiring that the clutch be to the floor in order to start.
So that plunger was just going right through the hole of that arm, and the starter reacts as if the clutch is still up.
I took a couple small felt furniture sliders my wife had bought, trimmed one to fit snugly in the hole, bonded it to the other one and epoxied it in. Car started right up, problem solved!
Not sure if you can order that insert from Mazda, but a trip to the harware store should have you back on the road in no time.
Hope this helps!
