My 98 VW New Beetle, I bought used will not start. Ran fine yesterday. The starter turns but car is not starting.

Hi I am Vortash you say you purchased the car yesterday had it been standing long if so what is the condition of the battery ?. Best thing to do is take it off and put it on charge overnight and see what the amperage draw is in the morning .. it should reduce as it is charged .. Have you a spark at the spark plug and if you do are the plugs in good condition some plugs spark outside the cylinder and fail under pressure , are the plugs wet indicating that the petrol is getting through or dry indicating not ? is the fuel fresh how long has it been in the vehicle add more to be sure .. check fuel filters are they clear and air filters ... finaly .. is there compression if you can place a compression tester in the plug port then crank the car it should read at least 120 to 150 psi or in the green if it has no numbers .. if it is low then the problem may be badly seated valves or cylinder head gasket ...... also check the fuses the it may be something as simple as that hope this helps Regards Vortash ..
