So, I decided to buy a 2001 audi a4 1.8 off a family friend. The car been sitting for 7 months, it ran fine before they left sitting in their driveway. Before I started, made sure to change oil, New gas, New battery, checked fuel pump, fuses etc. After all that the car cranked but never turned on. I notice the rpm wasn't jumping while cranking, so I changed the crankshaft sensor, no luck there either. Anyone have ran thru this problem? I did notice the intake was sucking air before I installed the crankshaft, now its not.

 

Has the battery been sitting for 7 months too? It's probably dead, get a charge on it.

 

its a brand new battery.
Just changed the Camshaft sensor and cables, no luck.
but i just took a look at the ignition coils, and they are extremely rusty inside.

 

Unplug the cable form the coolant temp sensor and try start it.

 

no luck.
put a Code reader in. throwing
