HELP - Only Starts with Camshaft Sensor Disconnected

[evanw0920]

Hello everyone, I’m here seeking advice for my 2007 Chevrolet Suburban LT 1500 5.3L FlexFuel. I’ve been experiencing an issue where the engine cranks but won’t start. The only way I can get it to start is by disconnecting the camshaft sensor. I’ve already replaced both the crankshaft and camshaft sensors, but the problem persists. Additionally, my scanner isn’t showing any codes. Any suggestions or advice would be greatly appreciated. Thank you in advance!

Will it run if you start it with the cam sensor disconnected, but reconnect it? If so, then do a CASE relearn with a capable scanner.

Yep, i've tried doing that and the issue still persists
