Does your underhood light come on ? or if the key is in the ignition with the drivers door open , do you hear the door chime ? If not , it sounds like a bad battery cable connection or a dead battery
It would be helpful if you can explain the " won't start " Does the engine turn? If it turns does not fire? Was it running before?
There could be quite a few reasons why the car won't start. If cranking or turning over the engine is the problem and the starter is good, it may be the battery. If the engine turns over but won't start you have bigger problems...
check the compression on it if it turns over and doesnt start you might have fried the rings
Fuel, and spark. Check for these first.
If the 93 Stealth came with a crank sensor but it does not have one now, then it will not start. The sensor shows the ignition coil when to send power to the spark plugs.
buy a pcm
check for fuel or spark
Well, one sign would be that the engine turns but does not fire, or engine stalls here and there.
crank sensor is bad
tps or idle speed motor
Check Crank sensor located in the block near the ac compressor
Be sure it is in park or neutral.
