Thanks for all the feedback, much appreciated. The cruiser was running fine and then one day it just wouldn't start. Think the problem is ignition related. New to cruisers so will probably be tapping into the knowledge available at IH8MUD on a regular basis.
Wondering if anyone can identify this electronic ignition system. It's in a 1974 FJ40 I recently purchased from a person in Dallas, but it originated in California. There are no manufacturer's information or part numbers on the unit. Thanks.
