I found this site while trying to work through a "cranks but no start problem" with my 91 Sidekick. After filtering through some 70+ pages of posts and comparing symptoms found with my Sidekick to those experienced with other folks, I replaced the ECM against the advice of one of our local mechanics. Guess what? Runs like a top!
Thanks to everyone who contributes both problems and solutions. Saved me a pile of guesswork and probably money!
