91 xj no start
my daughter's grandpa has a 91 xj and has a no start issue. he replaced the old motor with a good running motor from a rear ended 98 xj. he swapped the stuff needed from the 91 to the 98 block. it cranks has fuel but not getting spark. i know he has tried new sensors, distributor, and i believe a new module. any ideas i can relay to him?

Tell grandpa he should join the Cherokee forum LOL!
I can see too many questions that need answers at this point. He's switching engine management systems (from RENIX to OBD). A big change.
