Symptoms of a faulty fuel pressure regulator
I can't figure out what's wrong with my van, it has hesitation, no power, and backfires sometimes. I can't figure out what's wrong help???
How can I help? What is your skill level and what test equipment/tools do you have? Check fuel pressure? Timing? Valve issue? Do you have a vacuum gauge?
