tach not working i pulled my motor apart an painted the engine bay. but before that it worked.
we pulled the heads off, tore it down to a shortblock, threw arp rod bolts in but didnt leave cyl 1 tdc. threw cam/lifters/ls2 chain
so some people are saythng thats why my tach doesnt work because the crank an cam are out of sync an i should do a crank relearn.
i turn the key on an it makes a sweep, i gues thats a way of teling it needs a relearn as i was told.
no cut wires or poinches, new cam sensor.
maybe bad ground due to painting block an bay?
its driving me nuts an im throwing 2 codes ones p0342 n idk wat the other was.

Check the cam sensor and the wiring to and from that sensor. Also the grounds on the back side of the cylinder head; make sure they are clean and tight!

And on the code reader I hope it was cheap to rent because you can buy one for $70 now if it reads all the engine peramiters that is a different story but just codes you can get one cheap.

New cam sensor wires r clean i pulled the loom back to main harness..
Im moving the ground above starter up move to a spot i knows clean.
Also on the starter the 5/16 nut is that a ground? If so its not tight.
