FUEL PRESSUE TEST
Rent, Buy or go to a shop with a 0-100 psi manual fuel pressure gauge.
Have the engine off.
Find the location of the Schrader valve on the fuel tail. Use a rag to let off the pressure built up in the rail. Screw on the gauge and have someone start the vehicle. Pressure should be above 40psi under all conditions. Low pressure would indicate bad in-tank pump, or clogged sock covering pickup area or possibly clogged fuel line.
