Got it turning over fine and got spark but the fuel pump is not priming on ignition anymore and no fuel getting to the filter. Never used to have a problem since I swapped the relay over months ago and have tried using a known good one today aswell.

Do I need a new pump or is there anything else I can do/check for first?

If I do need a pump what should I get? Think its got a standard pump on it already but running stg2 T3, FMIC, Magnex, K&N on a rebuilt engine now.
