Plug gap is correct, I was surprised how wide it is, I'm used to old school cars with a gap of .025 All plugs look good.

It's definitely the coil pack not sending any power to the plugs.

My problem is I could not find a supplier listing the coil pack for a Chevrolet here in the UK, they are not that common, so I bought a coil pack for a Vauxhall. (They are All General Motors cars, end the engine in my Aveo is definitely used in a number of Vauxhall cars)

They look the same thing, but I'm wondering if we have a daft situation where the Vauxhall one although it looks identical, expects different wiring?
