Why would your car not start if you changed the camshaft censor. on 2003 Dodge Ram 1500

I changed it after I had it put on a diagnostic machine and the problem still exist,why would that happen

Asked by for the 2003 Dodge Ram 1500
Because it's not always the part itself that is the problem. If the part is the only issue, why would you have technicians?
AMEN!!

Sometimes the shop will get a code for the cam sensor, but its actually the crank sensor that is bad. Have them both changed.
