I am wondering if there is a way to test the fuel rails for correct pressure and flow, the diagnostic troubleshooting guide says the return line can get damaged from an incorrect engine movement, or maybe zzp's quality control sucks and their fuel rails failed prematurely.

I usually go to the dealership for a diagnoses because they can usually say exactly what is wrong...


Haha...just messing with ya. Or am I??
