When you crank the engine you are getting spark? Sounds like yes.
Next are we getting injector pulse when cranking the engine?

Basically, each injector should be getting 12 volts like you are seeing and then the PCM grounds the injector in order to open it.
So, we can have power to the injector, but we need to know if the PCM is grounding it to command it on.
You do this by the guide above or use a test light or Noid light on the injector connector and crank the engine. You should have the test light flashing or blinking as you are cranking the engine.
If you do, then we have spark and fuel being delivered to the engine which leaves air and compression as the only other things needed in order to get the engine to start.
I suspect the engine is getting air, so we need to check the compression.

If we don't have compression then that is the issue if we do, then we need to pull the plugs and see what they look like. We may have a weak spark that is not allowing the engine to start.
Or we could have too much fuel but let's start with this and go from there
Thanks
