Crank but no start (1 Viewer)

[timjtitus]

New to me 2002 is cranking but not starting. Before attempting to start I checked the 20 amp radio fuse because the radio went out, seemed fine. I also pulled the efi fuse to compare it to the radio fuse. Both seemed fine. I then unlocked the truck with a newly cut key that I haven’t programmed yet and attempted to start it with existing master key.

no start. I then replaced the fuse with new 20 amp and 30 amp with still no start. Attempted jumping it also.

is there a chance I deleted the keys by unlocking the door?
