1990 560SEC starts then dies, then restarts & runs normal?
 

Every time I start my 1990 560SEC when cold, the car fires right up runs for about one second and then it dies. It restarts again just after a few cranks and runs normally after that. It doesn"t matter if I pump the gas pedal first or just crank it cold. When it's warm the problem does not occur. Is there something I can do to fix it?
