Tach not working question
Does the tach work off the cam or crank? I just put in a new LSX motor and the tach gauge does not work, so I'm wondering if I have a bad sensor or something else is wrong. Thanks

the tach runs off the cam sensor, check the ground from the engine block(behind the altnator) to the frame(driver side under the fuse boxes). also check the pins going into the pcm from the wiring harness. i would go over those first before you pull the intake off to change the cam sensor
