I recently purchased my 87 Spider Veloce. The car ran pretty well the first couple of days and then it just stalled out after stopping at a stop sign. When I tried to re-start the car it sputtered for a few seconds and nothing. It acts like it wants to start but seems like it is not getting fuel. Could it be a bad fuel pump or a clogged fuel filter? How can I find out what the problem is? Any suggestions and advice is greatly appreciated! Thanks!
