Re: 2012 262c cat runs for a few minutes and starts misfire and blow blue smoke worse at rpm.

fuel starving issue

replace fuel filters, including inline filter if applicable

then retest

if problem persist, replace fuel pump, check fuel lines and tank

 

very unlikely injectors or injection pump issue

seen this problem 3 times in the last 6 months, and fuel pump and filter replacement fix it in every case

cleaned the fuel tank once too

 

beware, if you check the fuel pump and it seems to works fine, and plan to go for a costly injectors or injection pump, don't

 

do the above first.

2012 262c cat runs for a few minutes and starts misfire and blow blue smoke worse at rpm.

Seams like it runs out of fuel. New fuel filter new lift pump
