I changed the head gasket and now there is only one click when i turn the ignition and one more when i release it, I can turn the motor manually and I’ve had both starter and battery tested, what could be the problem.
Most likely problem is the battery. Even though it tested good, it can still be bad. That being said, the first thing I would try would be a NEW fully charged battery. If you have then you can check a couple of fuses. The 250A Battery fuse and the 30A Starter Relay fuse. Then test the relay. And check connections at the starter and battery. Since you get a click I would think the PCM is sending a signal to the relay. You can check that as well if you determine the relay is not activating.
