So, we're taking about a 2000 3500 454, and it has hard starts, or what I'd call failed starts.
I read on another forum about basically the fuel system losing its prime when the vehicle sits, But I think this was on a different vehicle. Their suggestion was to turn the key to kick on the fuel pump, prime the system, then turn it back off again. Turn the key again, let it prime, and see if it starts.
Well I tried this, and it appeared to help. I'm thinking also that sitting on an incline makes the problem worse.
So, the question is in the title. Do these trucks have fuel pressure regulators that need to be changed, or do I need a fuel pump?
Another issue that may be unrelated, or it may be a symptom of this same issue, is that once the engine is warm sometimes I'll get a rough idle and a little hesitation on take off. I just changed the fuel filter, plugs, wires, cap, rotor, and air filter.
Thanks for the advice.
