im assuming that you are checking fuel pressure at the schrader valve....next step would be using a noid light on one of the injectors to verify they are geting signal.

Yes from a 92 xj 4.0 into a 93 xj that had a 4.0. Even if the fuel injectors was not working right. When i spray starting fluid in it does not even try to run on starting fluid

How does the spark tester work? Are you sure it's accurate? Have to tried pulling a plug wire and cranking it to see if it will arc to something? It really sounds like you aren't getting any spark in the cylinders. Also, are you sure you haven't flooded it from too much cranking? We had that issue at first after we swapped my engine.

Ok you said you have spark. Whats the fuel pressure? are the injectors getting a signal? were did you put the spark checker? from the coil to distributor? or from distributor to spark plug. did you double check your grounds and wiring harness connections?
