How to reset security system.?Replaced head gaskets and water pump. Had to do some wire repair from a snake moving across wires till rubbed raw.

Car started fine before replacement. Now fuel injectors will not pulse. Have spark, air and fuel to rail. Security light on and not flashing.

Car cranks but will not start.

Using alternate power to test injectors they work but not when on the harness? What can I do to fix this?

Based on cargurus.com discussion this could be a common problem. Turn the key to the on position for 10 minutes then turn off, repeat 2 more times, the system should reset.

I have don't this multiple times since the replacing the head gaskets. I check all the electrical spark plugs plug wires with a multimeter and everything is good but the injectors will not spray while connect to the harness. Harness has no shorts. Checks out on multimeter. Injector spray with different power source. Even tried new injectors but won't spray.
