Timing on the 1990 4.0L / inline 6-cylinder engines are set & locked at factory and can only be changed by modifying parts... and modifying the parts is a BAD idea since you are masking a problem rather than solving it. You'll end up with a worse issue when you are done.
If you do have a timing issue it is either a stretched timing chain or sensor related.
Timing is controlled by the computer and is not adjustable. Computer timing is determined by finding TDC (top dead center) with the CKS (Crankshaft position sensor) and CPS (camshaft position sensor) but when either goes out you will generally have an engine that stalls intermittently or a 'no-start' condition.
