turns over but want fire.
Ok, so I put the motor out of 98 XJ classic I crashed in my 2000 XJ sport. after changing the wiring harness and putting all new sensors crankshaft etc. I've put 4 ECMS on it all relays are good I finally found the automatic shutdown relay under the dash on driverside on kick panel changed it and finally started getting fire the plug that plugs into the coil but no fire through the new coil. the 98 motor is a distributor motor and the motor I pull out of 2000 was a coil pack motor. please, please if anyone knows why its not firing, please let me know. thanks
