Message: [QUOTE="webb06, post: 1568375, member: 7680"] Will start and run 1-2 seconds, if that, and immediately dies like key is shut off. Will restart and immediately die. Found a post on another forum about a pcm/tcm issue causing similar symptoms so I unplugged trans harness and started engine with starter jumper wire and engine will stay running. Ran it over 30 minutes idling today. Plug trans harness back into pcm and stalls within seconds. Swapped pcm with another. No change. Unplugged trans main connector on trans case and reconnected at pcm. Will idle all day. Swapped ficm as well because voltage did occasionally drop below 40v. No change. Anybody ever dealt with this? I can’t imagine anything inside the trans causing any issue like this…help [/QUOTE]
