Can someone tell me the proper way to perform a compression test on our trucks. Changed the sparkplugs and had one plug that looked 10x worse than the others. Just want to make sure the cylinder is ok. Also roughly what psi should I be getting from each cylinder? Thanks

Thanks bestatchess.
Dumb question : how do I release fuel pressure??

 

[bestatchess]

Tbe manual references a Consult II software feature to release fuel pressure. w/o software, pulling fuel pump fuse, run engine until it stalls, and then cranking it a couple of more times is supposed to take care of it.
