I recently rebuilt the 1FZFE engine in my 1995 land cruiser. Prior to the rebuild, the vehicle sat for a year. Just prior to pulling the engine, the starter was acting as if it was weak even with a new battery. It would only engage the flywheel and turn over the engine one in twenty attempts to start. I eventually bench-tested the starter and it seemed fine. I recognize that bench testing is limited and doesn't really test under load. I replaced the starter as part of the rebuild with a reman starter. The new starter bench tests successfully but exhibits the same symptoms as the original. It is very intermittent and largely not functional. Again, the battery is new and fully charged and there is 12.6V present measured both at the battery terminals and at the starter. I'm at a loss how to troubleshoot this further other than replacing the starter wiring and/or buying a 3rd starter. Any thoughts would be appreciated.
