not a dodge but in the same family, i am working on a 96 jeep xj with a 4.0. i drove it to my house and did a motor swap. its a crate from advance auto. now it cranks but will not start. it has all new crank and cam sensor. it has spark all the time from the coil. but only has spark on cylinders 3 4 5 but not 12 and 6. Any ideas?
