Car has been running fine for half a year since having time to wrench during this whole covid thing. I've been driving it a few times a week since March with only 1 issue. Wife took the car out yesterday cause I needed the truck. She fired right up, and got her there. On the way back she couldn't hold it, and stopped to take a leak, in a spot a pot . Car wouldn't start after that. We came back today thinking it could be cps, since I do have a leaking water pump. It's on my radar to do front motor maintenance. Figured it would start when cold. I had a recent incident where the car would crank, and the tach wouldn't respond. Seemed to fire off time, but started eventually after waiting it out for a little bit. Car still wouldn't fire up this morning. When I turn the key on, the fuel pump primes. There's still a constant hum from it after the prime. The coolant fan also immediately comes on, which I'm not sure is normal. The tach responds and moves slightly off 0. When I turn the key to start, the engine cranks, and the tach responds by moving up to around 500 or so. It doesn't fire and there's no indication of spark. I tried to pull KOEO codes, but was unsuccessful. My scanner says vehicle not responding. I gave the CCRM a few love taps to no avail. From what I've read it could be CCRM or PCM. Suggestions where to start?
