Smells problem
1995 Volvo 850 V12 Two Wheel Drive Automatic

I am not getting gas to the inject rail, so I checked the lines and filters, they were fine so I went to the fuel pump cover in trunk, took it off and found a conecter plug undone so I pluged it back in, then turned it over and it cranked for few minuets then it quit again, so I pushed the gas valve on the rail and gas flowed to a stop, now nothing, What do ya"ll think.
