how do i doa fuel pressure test on my truck?

00 5.3

can i hook a gauge up to the crossover pipe where it has the alittle beed thingy on the passager side

and do i turn it on and run it at idle or rev it up and if so how much?

and what psi should i be seeing at idle or reving it up?


i have a p300 code and im trying to troubleshoot it to find out what could be the problem

truck has new injectors, fuel filter, plugs, wires

and air filter is good also


peace
