I recently replace my 1990 xj6 4.0 engine with a 1991 xj6 4.0 engine. I can not get any fire from the ignition coil. I have fire going in though. I have fire going to the injectors. I changed the crankshaft censor. I noticed that their is no fire going to the crankshaft censor. Any suggestions.

 

Check for the OOPs first. Look and make sure all grounds are in place and making contact, all connectors are in good shape and plugged in good. Check all fuses that supply the engine. I don't have access to the wiring diagram for your car, but look and compare and make sure that the wiring and computers match.
