i was wondering if the fuel pumps were common to get weak or maybe the FPR because when this truck sits over night ill have to cycle the key a few times and it starts right up. otherwise it will act like there is not alot of fuel pressure and run shitty at low rpms for a few seconds

pull the vacuum line off the regulator if fuel drips out it is definately bad. if not it doesn't drip it does not necessarily mean it is good but this is a good quick check.
