- - slow to start (https://www.dieselbombers.com/24-valve-2nd-gen-dodge-cummins-98-5-02/121078-slow-start.html)

this truck is a 2000 or '01, 197,000 miles, belongs to a friend, a few weeks ago it was a little slow to start so he changed the fuel filter. the truck sits most of the time until he wants to pull something, i used it to haul bulls today and noticed it was a little slow to start. it seems to have to crank over more than it should.

my question is, is this a sign of a weak fuel or lift pump? he bought the truck with 182,000 miles a few years ago and as far as we know this is the stock fuel/lift pump.

Sounds like a fuel issue, he definitely needs to replace that stock LP with an aftermarket LP. How long does it crank before it starts? Checked for codes?

a few seconds 2 or 3 times. no i forgot to look for codes but will in a few days. new baby boy takes priority.

the only 2 codes that came up were 0122 and 1698.something about apps. will this cause a slow start?
