ive run out of ideas and hopefully you tech's can help me out,i parked up at a mates the other day with no problems,went to start the car when leaving and it would turn over but not start up,1st i thought my fuel pump had stoped working,but ive tested the fuel pump straight from a battery and it spins,tested the wires to the fuel pump and theres no reading,i searched and found to check fuel pump relay,it still clicks and seems fine,my mate no's how to test relay and is coming round 1day to have alook,just wondering if theres anything else i could check.

any help would be great
