Yesterday I drove my car across town and it was working fine when I shut it off an parked it. When I came back about 10 mins later to start it back up and leave it wouldn't stay running. First turn the fuel pump starts and pressurizes the rail like it should i'm seeing about 50 psi but once I actually start it it starts then when the electrical system kicks in at full power it starts idling really rough an then dies and as this is going on the rail pressure is just tapering off. When it gets down to 11 psi it just dies. I replaced both fuel pump relays cause we thought that was it but it didn't work. I need some help! Any ideas?
