So I’m totally stumped. My XJ6 was running beautifully until the other day I was driving home and it just died. Somehow got it to run a bit got it home and now it just won’t start.
I have a strong starter and spark so I moved on to fuel system. I did the jumper test at the fuel pump relay and I get power to the fuel pump but no fuel coming to the fuel rail. I tested the AFM flap and can hear the relay click. I went to the rear of the car and directly powered the fuel pump- still no fuel. Then I bypassed the changeover valve directly from one of the tanks- no fuel. This was a brand new fuel pump.
I changed this fuel pump pre-emptively because the other one was too loud. I kept it anyway and tried to hook it up to see if that pump would work. I get nothing pulling through. Could I have two bad fuel pumps that were working but miraculously now don’t? Something doesn’t smell right:)
Can anyone help? Thanks!
