Re: fuel pressure test
rear of pass side fuel rail, theres a schrader valve for you to hook up a FP gauge.
Look on your SPI sticker (glove box, white sticker w/ lots of 3 alphanumeric codes). Look for "L98" --> 5.7, or "LB9" --> 5.0
Different pressures, do a search for the correct pressure for your engine, then hook up the gauge and turn on (but dont start) engine. Check gauge.
