Hello, my 2003 A6 3.0 auto. wont start, about a month ago it died as I was coming to a stop at a intersection,pushed it off of the main road and checked fuses ok, I sat there cranking it over and over and it would almost start a little and then die,so I sprayed a little starting fluid in intake and it started right up and then die, so I figured its the fuel pump,towed it to a local garage and they figured the same and changed the pump. When I got the car back it was hard to start, it was cranking fine but was taking 2 to 3 turns of the key to start, then it would run fine,so it was like this for like 3 weeks every time I went to start it, fast forward 3 weeks,go out to go to work already running late, all it does is crank, wont turn over, so I really wear the battery down which I think is already going since the winter,call the garage and tell them the new pumps dead, they finally come tow it,they think its just the battery and put new one in starts up runs fine,still hard to start 2 to 3 turns key cranking it over before it will start,but running fine,put new air filter,fuel filter,and ran some injector cleaner through and running great but still hard to start. Go out to go to work on Fri. dead again,cranking and cranking no start.I dont think its getting any spark,could it be cam position sensors of a crank position sensor, or coolant temp sensor. Any ideas appreciated sorry about long story.thanks
