how do you know its missing on 1 cylinder? what are the symptoms?

the injectors are held on by the fuel rail, i know on the ecotecs you need to remove the upper intake manifold to access the bolts to remove the injectors, im not too sure with the buicks setup.

Just unbolt the fuel rail and pull the injectors out.

I've a feeling I've got some VN injectors floating around in the shed somewhere.

Its missing because I checked the plugs and found which one it was, Thanx for the info, The symptons are, start motor, it idles good for 15 seconds then stops firing on the same plug every time, theres fuel on the plug no 1 according to the coil

I have also changed plugs and leads from different cylinders

Could be a dodgy coil pack.

Could be a dodgy coil pack.

my thoughts exactly, try swapping coil packs around to see if it follows the coilpack

If it was a bad coil it would be felt on the other plug the coil fires as well I think....

What are the odds of a new coil failing pete

very true, but it costs nothing to swap, and rules it out.
