can anyone advise location of fuel pump relay in 2006 Ulysse JTD? Have problems with cutting out and failing to start; dealer diagnosed pressure regulator on injector pump not signalling ECU to operate lift pump, and advised metal filings in fuel indicated HP pump breaking up.Replaced HP pump and regulator with new recon unit, lift pump still not getting power. Fuses appear ok and no such failure showed on FIAT diagnostic. Now, engine will run with temp supply direct to lift pump, but not otherwise. Wiring diagram indicates a relay, but doesn't id it or its location.Any help appreciated.Anyone else had similar probs? How solved?
