Start Problem
 

Dear Technical Services,

I have a 1993 Lexus SC300 with start problem. I have a new battery and new alternator. The engine can run about 30 seconds after started and then automatic turn off. The engine could not start after this. I let it relax about 2 or 3 hours, the engine can start again and has the same problem that I describe above. Can you help me to resolove this problem?

Thanks,
Dave
