HiCustomer Thank you for asking your question on JustAnswer.
Are you looking to find out how to set base timing? That vehicle is computer controlled and timing is not adjustable. Did you just replace a timing chain or cam?
Yeah, it is not supposed to. is there a wire harness hookup for the cam syncro on that engine? It may be a 1995. I have installed 1998 4.0 engines in 1992s i just leave that syncro dead in the hole to run the oil pump. But, if there is a wiring provision there for it then we need to get it hooked up.
Does it have a wire plug for it?
