Hi all! New here and desperately need help. My Trooper is a '91 4-cyl manual 4wd. 133 K miles and has been running fine even though it only runs on 3 cylinders. Cracked head and dead cylinder so I was told. I am mechanically dumb so any help will be appreciated! Cold starts fine, run a few miles and turn it off, NOTHING when I try to restart. No clicking or lights. It's like a completely dead or disconnected battery. Battery is fully charged and posts are clean and tight. After waiting a few hours it starts no problem! Problem is intermittent in that it doesn't do this every time I drive it. it started 3 days ago. Ideas?
Thanks!
