My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

Check your battery voltage while cranking and see if it is dropping to 10 volts as well.If it is not if it is around 12 volts check the wiring to the ICM for any corrosion or damage as low voltage (the 10 volts you see) may not be enough to allow the engine to start and may be due to ICM fault or wiring fault to the ICM.If this is or was already checked and found o.k. let me know so we can continue.
