I have a hard start issue. To get the truck to start and stay running I have to hit the pedal a time or two. Its a fuel injected 22re so that shouldn't happen. Once up and running it is fine, only happens at start and it's worse when cold. Attempting to trace the issue, I pulled a couple vacuum lines and found fuel in a couple of them. Mechanic friend says the fuel pressure regulator is toast. That makes sense doesn't it? Just wanted to get another opinion before I drop $100+ on the part.
