So I cleaned the alternator fuse/connection (the box is a bit melted where the blue tape is).
I also removed my clocks and turns out it has a different screen to the metal cage one in the guide but all the connections seemed alright there.
I checked my earth connection under the battery, that was fine, and I removed the battery to reset ecu.
Nothing changed though i did notice that the fuel pump wasnt priming so i changed the fuel pump relay (and uprated to the 'c' one) and it is a bit better.
However I noticed a pattern, if i put my key in and turn it the clocks are dodgy still and the fuel pump doesn't prime, if i then turn it off and turn it back on
without removing the key the clocks are fine, the fuel pump primes and the car will start. Though if i turn it off and remove the key before trying again then the clocks still mess up....

very confused now, any other ideas? I may just end up changing the clocks to rule them out!
