Question about Riviera 1999 99
I recently used the product Gumout fuel system cleaner in my 99 Buick Riviera it started with longer starts then today it kept dying then would restart then to just cranking over so i replaced the fuel filter the fuel pump still makes a noise and the car will start with starting fluid but dies and still no presure in the fuel rail
Have the high pressure fuel solinoid checked also fuel rail pressure sensor on the fuel rail it could be the pump some will run but at too low pressure also run a diagnostic check it may flag up a fault good luck PAUL@FIREFOX
