Question
hi i just did a intake gasket replacement on a 3.4 lt venture.i torqued to specs all bolts and re connected all wirering harness,it started on me but was running rough,i checked under hood to make sure but all seems fine, i have spark and fuel to all cyls.but it wont start,before i started on the project it was running rough i think that was due to the failing intake gaskets.also the owner was adding coolent as it was running low, without noticing it going to the crank case,the crank had nearly 2 1/2 gals of sludge,sludge had also seep through to the air flow sensor tubes, can give me some directions, thanks in advance

Answer
Hi Mehraj....did you check the intake for being straight, could it be drawing air via the intake...try removing the plugs...see if they are wet with fuel...if they are clean and dri them reinstall, then try to start...if you have fuel and spark it should go...check fuel pressure and all the obvious...clean connections and sensors...hope this helps...
