#3 Injector Harness No Power

[dherron]

Found that the problem was my #3 injector is not getting a pulse (no voltage). What could this be. The car caught on fire and we replaced that part of the harness. All the connections seem to be good. And i have put another ecu in it so i dont think that is the problem. Any other good ideas?

The power comes from the injector resistor pack to the injector. The ECU pulls the other side of the injector low to complete the circuit and fire the injector. If you don't have any voltage at the injector you need to start backtracking to the resistor pack and see where the circuit is bad.

The problem was found. Wrong wire was spliced.
