Hello -

Okay, so we are on the same page. You have a 1996 Cadillac Seville STS... What is the engine size in liter?

Are you saying when you first start it in the morning it starts fine but after it is driven it will not start?

You have changed the fuel pump and filter twice... Yes?

How many miles are on the vehicle

Please go to Auto Zone (AZ) or O'Reilly's (OR) and for FREE they can pull the codes to the car. Most important: Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for FREE also they can bring their tester out and check your battery and alternator.
