Hard starting and tach not working

Showing po 342 cam sensor low output. could this cause the the tach not to work? or does tach work off of crank sensor? car hard to start but run fine once started.

It could cause the tach not to work. Have you done any work on the car lately? Washed the engine bay?

Sometimes on intake swaps the wire will get pinched. Or maybe water got in the PCM. Or maybe the sensor just **** the bed.

Forgot to hook up wiring harness on passenger side of motor. Who would have thought there would have been a connector between the crank position sensor and the PCM.
