My Pontiac has no crank. I replaced the batterie, the starter, I tested the ignition switch, all the grounds to the engine. The TRS isn't bad. Everything works up to the flywheel. I know the engine is not seized I can manually rotate it. When try to turn it over the flywheel moves about a inch, everything stops and it moves back again.
I am stumped on what's wrong with my vehical.


No hydro lock
