The ECM seldom goes bad, it can but it rarely does. A faulty crank sensor could give you those same symptoms. Check all other possibilities before you condem the ECM.

Do you have spark at the coil? If not it could be the coil but I would put my money on a faulty ecm. Happened to mine and the repaired ecm fixed it.
Will the engine light come on if a sensor is going bad in a Chevy S-10 pickup?
The "Check Engine" light will illuminate when the ECM (engine control module) receives a signal from a sensor that is out of its parameter. It could be a faulty sensor or the sensor may be doing its job reporting a problem to the ECM.
What controls timing advance on 93 Chevy tbi ecm or ignition module?
The ECM does. The module is only a pickup and a signal conditioner. There is a tan wire with a black stripe that disables timing advance when disconnected, so maybe that's whats going on. Its near the realay center on the firewall.

How do you check the ICM on a 1993 jeep wrangler?
Check your low voltage input to the coil with the key on. If there are no volts, then either your ECM isn't sending the signal or you don't have continuity through the wire. If there are volts, bad coil. There should be specs on what it should read but I'm not sure what they are

Would crankshaft positioning sensor cause no spark?
Yes. On some vehicles, the Crank Shaft Position sensor tells the computer that you are trying to start the vehicle. Without that signal, the ECM will not control the spark coil.
On a 1993chevy z71 Coil has been replaced yet still gets no spark?
Check the cam and crank sensors, odds are the coil is not being fired because it is not being told to do so by the ECM, which in turn uses a signal from the cam and crank to determine if the engine is turning over and at what point in the cycle it is in.
