Truck cuts off when started cold..

[DatacomGuy]

Another issue i need to bring in to the dealership for, but wanted to get some input.

When the engine is cold, and only sometimes, i'll start the truck and it'll start successfully and almost immediately cut right back off.

To restart, i need to remove the key, re-insert, and start it. It'll start right up without any hesitation or choking and be fine the rest of the day.

Any thoughts?

Could be a bad O2 sensor. But that's really a shot in the dark without some diagnostics.

Have you checked to see if your truck is part of the recall?
