I doubt it is a california model, it was purchased new in Ohio. Is the VIN code part of the VIN number? Sorry, I am researching this for my boyfriend so we are back and forth on the phone as I am serching for an answer. He has been trying to get the truck to run for over a week now, and has replaced the fuel pump 3 times! Also, he replaced all the fuel lines. The truck starts, but will only go a few yards. I believe he also said the psi is low? Thank you SO MUCH for your time in replying to me!

Yes, the VIN code is part of the VIN#.
Have him spray carburetor cleaner into the air intake and see if that keeps the engine running. If so, he has a fuel delivery issue. No matter which engine (VIN code) it is, the fuel pump relay is located in or near the main relay/fuse/junction box. The code basically tells us which location in the box it is.

You said he mentioned the fuel pressure was low. How low? Can he rent or borrow a fuel pressure tester from a parts store to check? Have him listen for the relay and pump activating when he turns the key to On and Start. Have him use a meter or test light to see if the fuel pump (in the fuel tank, at the top) is getting power.
