Yeah, that truck hates you. drop it off here with keys and title and I'll run the snot out of it for you.... and I won't hang it upside down like you have haha
I have a 96 just like it, though it hasn't been parked on its roof yet....... Id like to find another (rust free a must) 96-older club cab 4X4 one of these days.

 

It seems to be fixed for now. Autozone **** ecm. Put a good ecm in it and haven't had any problems with it yet.
