I have a 1991 Miata with 15x,xxx.

I had recently had a problem with the car feeling rough, and changed the spark plugs, and wires, etc.. This fixed the issue.
About a week or so later, I was sitting at a light and the car just died. The miata idles low, so i figured it just stalled out. I went to start the car and it will crank, but nothing more, it will not turn over. I have changed the Cam Angle sensor (The one to the left of the coils) and changed the igniter as well. Still no luck and it is driving me crazy.

The car was running perfect, and then nothing. It will crank, but not turn over. I looked under the oil fill cap and saw the rocker arms turning, so the timing belt is still in tact. I am getting no spark at all.

Any suggestions?

 

bump

 

coil packs?

 

Could be coil packs. Check all the wiring to the coil packs to make sure nothing came loose and the plugs are free of water.

 

yes, on my 91 miata, I had the same problem, there was alot of moisture and lil water, dried it up and clean it, and i was good

 

I shall check the coil packs. I unplugged the MAFS and the car turned over, it would not run this way, obviously, but i plugged it back in and immediately died. I borrowed a friends whole MAFS piece and tried his, and it does the same thing.

 

just rip the pos 1.6 out and throw in the 1.8. the crank pulley is gonna give out sooner or later anyway and it could have already by the way your problems sound. if the keyway has givin in it can throw you timing off ever so often and make the car break up and run sluggish, not to mention bend your valves.

 

The keyway issue only affects 90 and early 91's and generally only if the key wasn't re-installed correctly after a timing belt change. Also, the Miata engine is a non-interference engine.

Have you gotten water in the car lately? The ECU on your car is under the front of the passenger floorboard. If water got in the ECU it could also cause issues.

 

damn, i didmt know it was non-interference
