the fuel pump supply line will be the one thats under pressure

I'd suggest to remove both fuel lines at the engine end put them into a bucket / jug and flick the ignition on

the pump should run for 2 seconds and you'll then see which line is the feed and which is the return

I've already done that and the fuel is coming out on the line that's coming from the front but the engine still will not start something is blocking it between apply line and getting to the injectors
