I took a look behind the instrument cluster and sure enough there is a 10AS immobilizing system there as well as the spider underneath the LH seat in the black box. Someone has cut and removed the wire a position 4. I need to read more about if mine has been bypassed. I don't have a key fob, so it has to have been at least partially bypassed? I have 2 wires coming out of my underseat spider with a fuse. When the fuse is removed, the engine turns over but doesn't start which is different than my usual non starting issue where the engine won't even turn over and it sounds like the starter is not activated. I've switched out the starter relay for one that I know is a working one and it doesn't seem to make any difference with the intermittent starting. With the truck running it also bogs down and shuts off like it is starved for fuel. Not sure if these things are related, but it is not drivable now.
