2000 Audi A6 Quattro Q&A
2000 Audi A6 Quattro Question: Engine does not start even after replacing with a set of new Spark plugs.
In orderfor a engine to start you need three things spark, fuel, air. For a 2000 you can with good ear have someone cycle the key, or crank it you should be able to hear the fuel pump come on. If you can hear chances are good that it is functional,but still a fuel pressure test will be needed. Now for spark,get a plug wire leave a 1/4 air gap have someone crank it if you get spark you may need a fuel pump. These are just the basic. - Randico
