Hey guys im new on here for the past few weeks ive had issues with my truck at low rmps it will idle irraticly an usually shut off so I thought it might be the idle air control changed it. No changed had another tp sensor laying around still no change it shows no codes. Pulled a vacuum test on it its holding at 16 or so. I pulled the egr off it had a pin whole in the diaphram. So I got another one still no change. I checked all my spark plugs their new and the wires wires an cap n rotor. So then I checked fuel pressure it was holding at about 32 psi. I am completely out of ideas. Not sure if the computer is going bad or a bad fuel pump or even a bad crankshaft sensor. I would really appreciate any help thanks guys.

32 psi is too low

I changed the fuel pressure regulator do u think the fuel pump is going bad or maybe it has a bad ground. Thanks

Always good idea to check grounds but what psi is other tank?

I have a single tank. Would the crankshaft sensor effect this at all
