Code 12 but no spark help

[Mordred]

Hey guys I have a VN series two I had been having trouble starting the car for a few weeks would finally kick 2nd or third times, It also began dying whilst I was driving it where the power was instantly lost the would stall.

My ECU is giving a 12 code, I have check my leads and my spark plugs yet I have no spark?
I checked the coil pack and it has the right ohms ect, also there appears to be power to the pack.

Is this simply crank angle sensor or something or the like?

ok, my bors vs had a the same problem and his turned out to be the the pins on the plug that connects to the coil pack had stretched apart a bit, so if you undo the 1 screw and remove the plug have a look and see if you can notice any stretched connection, if you do you can close them up a bit using something like a pin, also check for corrosion

the DFI module (module under the coil pack) doesn't always throw a code when it fails
But the process of elimination method can be rather expensive....
the best way is to get someone to scan you the ignition system diagnostic flow chart from the GMH service manual and step your way through it. It might turn out that you have a bad connection somewhere or a break in a wire.

Thanks guys,

I have a workshop manual and have gone through the steps of checking the coil pack resistance ect ect the last thing it says is try replacing the ignition module. I'm going to try one from the wreckers fingers crossed.

I've checked the connections and the wires as best I can and haven't found an improvement

while it's not the exact same car, someone in my street had a VT that would not start, it was towed to Holden and they couldn't fix it, in the end he replaced the motor. Turned out to be a broken/loose connection inside the DFI module or the connections from it to the coil packs.
