I have posted a video link of my 1998 Audi A4 2.8 v6 trying to start. It will turn over but not fire or try to start. I have checked and it is getting spark and fuel. New plugs, wires, coil packs and fresh gas. There is no MIL light on and have checked all fuses. Below is a video to the car, I know it would be easier to diagnose in person but at least take the info and video I have given and throw me some ideas.
