cam walk?
cam walk? Whats the best way besides draining the system an pullin timing cover? I heeard if i pull my intake off an valley cover. i can check it that way?
Reason being my tach doesnt work an worked fine before install. An i changed cmp an looked at the wires to it.
Thanks

Cam walk wont affect the tach signal, besides it has nowhere to go unless you forgot some parts. Bearings keep it on the proper axis of rotation. Retainer plate keeps it from moving forward, timing gear keeps it from moving rearwards
When you did the cam swap, is it possible you knocked the crank sensor when locking the flywheel when removing/installing the balancer bolt?

Everyone says crank sensor wouldnt effect the tach not working.
I puled my motor out for the swap. Put all new gaskets an arp bolts.
I put arp cam plate bolts on with arp lube not locktite. I didnt pull my motor out with cyl 1 tdc. Some people say a crank relearn is needed others say no
But i read somewhere on here from 04 of a guy that had same prob, an hia cam bolts backed out moving 1/4 inch an didnt make tach work

If the cam sprocket bolts backed out that far, they'd dig into the timing cover
The crank sensor controls the tach, I dont know how else to put it. Cam sensor's only function is to let the PCM know which stroke the engine is on. After start-up it is not used again

crank does spark, cam does individual injector/spark timing. Most all sequential EFI engines do this. Batch/bank fire efi's don't use cam sensors. However, with the computer controlling 8 coils, the cam sensor must be needed, just like injector control. Your tach signal will come from your crank sensor.

Cam sensor behind the intake controls the tach. Make sure it isn't broken or unplugged. My sensor went out and i had to get a new one few years back. Thats all it is. Nothing to do with cam walk, or crank sensors.

Definitely not Crankshaft Position Sensor, you would not get any spark.
This is a general test procedure, use at your OWN risk! Pin 1 should be 5V, Pin 2 should be ground, and Pin 3 is your signal. With the engine cranking/spinning, Pin 3 should be between 0-5V.

So i guess ill return crank sensor
When i start the car the speedo an tach makes a sweep then back down n tach goes to 0, someone told me it needs a crank relearn
