Author Message   Locs_530 Posted on Saturday, November 15, 2014 - 01:41 am:        i just picked up this fine 2000 thunderbolt s3 not running and in pieces,a few days later it in one piece again but only runs on one cylinder ! a closer look found that it only has injector pulse to one fuel injector,it has battery voltage on one wire but never gets a ground pulse from the ecm. i have done a continuity test on the harness between the connector and the ecm and all is good there. was wondering if the sensor on the timing plate could be bad,causing this i dont think so because it has spark and injector pulse on one injector. my other guess would be an ecm failure? not sure any input would be greatly appreciated .
