Message He also checked the fuel injectors with a noid light...all injector plugs are firing...the cylinder that has no spark also has a new fuel injector, coil pack, and spark plug. Voltage on coil pack side of PTU is 14.6v and that is the same all the way to the coil pack. If the center wire is piggyed from the ajacent coil pack, it fires the coil that is not fireing now...that tells me that it has something to do with what the center wire on a coil pack does....If the voltage is 14.6v then it should fire, unless the ECU is supposed to send a "Pulse" to the coil pack.

If this is the case....It MUST be the ECU
