Any suggestions on what else to look at would be appreciated. Drove car home after filling tank with gas from a reputable gas station. Next day my wife tried to start car, it would turn over fine but would not fire. Spark to plugs checked out ok. Fuel pump turns on when key is switched on . It has pressurized gas at the regulator. My shop manual says to check the fuel pump relay,but I have not been able to locate one on this car. pulled an injector line and no fuel was visible at the line.
