Knocking noises!

So is a silver not powerful enough to get the car started?

I’ve just changed it to a silver (didn’t have a silver plus) and thought that should be ok, still being a 063 and all but just changed it and now it’s exactly as it was last night, still turns but just will not fire!

Turns over fine does it? yes… ? okay so do this then remove all 4 plugs… are they wet with fuel (or can you smell fuel from turning it over?) If they are wet then your getting fuel so check the spark by laying the plug on the block (or earthing it some other way)… if they all spark nice and bright then put em back and try again.

However, I guess you tried all this and its still a pup? It has to be fuel or electrics unless you have been messing with other things like timing and ecu s/w etc…
