I just fixed a guys 2001 Mexi Beetle the other day. It had a dead fuel pump after being stored... (3300km actually on the car).... and during the process of getting it running, he took out the plugs to clean them, and same deal. wouldn't run right... checked the car out for him and found wires crossed, cyls. 3 and 4. fixed that, cranked her up.... sweet purring little fuel infected motor....
