Hi, any trouble codes? I'd want to check circuits at the dual crank sensor, if no injector pulse.

What about your security system?

The crank sensor should be located down by the crank pulley. Four wire connector, sensor feed-- sensor ground-- the other two wires are signal wires, they should have a pulse, engine cranking.
