The tach is not a foolproof test because some trucks never have the tach register when cranking.... It could mean that the new one is bad though...
do the other tests first.....see if you find anything. You have fuel to the injectors if the pressure is good, which means it has to be an electrical or mechanical condition not allowing the injectors to fire...
The other thing to make sure of is that your batteries are fully charged...
