So this morning I had a look at the coil packs and they seemed fine no bad connections or anything, removed the fuel pressure gauge and then fired it up, then I turn it off and put the spark leads in the correct order!
Measured the voltage at the battery 14.4v turned on the lights 13.5v, rear fog and main beam and I was dipping into 12v territory. Thanks for the tips everyone my finger was hovering over the "buy it now" button for some coil packs last night, I did check the earths, but I was paranoid about good earths when wiring up the engine and the earths were solid.
Going to take the 1.8 alternator off the 1.8, change the pulley on the alt or the 1.6 engine pulleys and see how I get on. No money spent and a easyish solution.
