were do I start? I am getting 60PSI at the port. Turn key off and I have constant pressure for 30 min or more. So I know the regulator is good. The Fuel pump is 2 yrs old. The fuel filter I changed in March of this year. Do you have some suggestions on how I can check the spider? I am reading conflicting reports on google.
Could this be an internal engine issue?

I'm not a mechanic by any stretch, but I have replaced just about every electrical sensor on this truck since 2012 when I bought it.

Thanks for your help. I greatly appreciate it.
