hello to all, newbie to the forum,... now a little background I have a 2005 trailblazer 4x4 that I bought 5 years ago had 89.000 on 4.2 now it's got 109.000 and it's been bulletproof no problems till now.......
Now its starting to have problems starting on the cold mornings 32- it will start but it takes some cranking and it acts like you lost a cylinder on start up then clears up, last year in the freezing cold it would fire right up no issues...now the first thing is to replace the plugs I am assuming they are the factory originals...what else to look at??fuel pump pressure??
the other thing is, does it have a fuel filter??? and where is it?? I have looked but nothing..also finding one, nothing at auto zone, oreillys, advance, rock auto claims to have 3....
thanks in advance.........
