Yes sir, I may have it tested just in case but it's only 2 3/4 years old...duralast gold. Car cranks strong until it'll pull all the amps from the battery. Sometimes it sounds like it's trying to fire too but it's weak

The reason I asked was the 9.464 volts to the ECU. I tried to google the voltage needed to make the ECU happy but could not find the number. I have heard that anything lower than 10.0 and the ECU will not fire. No experience myself with this issue, just trying to throw out ideas and see what sticks.

Ah, I see. I'll double check it with my multimeter at the terminals. This was after cranking it for about 45 seconds
