IWhen my truck threw that exact code. I did some research and then called a tech and that’s the forst thing he suggest and forst thing I did and there’s been no hiccups since! Do you have a hand held v2 reader or maybe a edge insight cts 2-3 digital read out? If so it will show you your FRpsi, injectors flow rate and everything else. Cp3 rarely go out. But it’s possible..
sorry I couldn’t be of more help..
133k seems low for injectors or am i off my rocker?Sounds like injector time to me as long as the supply side of the fuel system isn’t going deep into vacuum when the issue is present.
Sounds early for me too, that’s why I mentioned measuring the supply side for excessive vacuum, or because he now has a lift pump big drop in pressure, when the issue is present, first. If there isn’t a supply side issue, which is doubtful with a lift pump, then I’m heading towards injectors. If time/money is available, I am sending the injectors out for testing first.133k seems low for injectors or am i off my rocker?
Is there something that could have caused them to fail that early or... just fault?
