1999 2.7 3RZ camshaft sensor

I have a 1999 2.7 3RZ just changed the gaskets through motor and timing chain, cranked the truck run fine I drove it approximately 20 miles shut truck off for a few hours had a hard time cranking again but finally cranked and shut it back off woke up next morning to go get in it and wouldn’t start. Hooked a computer to it and it’s throwing a code for the camshaft position sensor, I’ve tried two new sensors and a new plug still won’t start. I’ve checked and cleaned all the ground so can find. One ground on throttle body one beside battery on fender one ground next to the coils. Am I missing anything or what is the next step?

 

I flushed my coolant system 6 times
Would not start afterwards

turns out (with help from members here)
Was the CTS(one on back of the head

(Which I had just replaced 3months earlier)
