Idle stalling and sputtering

I need to find out how to test the fuel relay and fuel pump. I would also be open to any suggestions. Initially stalling occurred without missing (spark timing ) now stalling occurs frequently even while driving.

Get a fuel pressure gauge and screw it on to the fuel service port on the fuel rail. It looks just like a tire valve. You should have around 45 psi fuel pressure. If the pump is running, the relay is good.

To test the wiring/relay, you can take the relay out and jump the hot prong of the socket to either of the other prongs with a piece of wire or paper clip. this is only for testing. DO NOT drive the car this way, it can be dangerous.

Thanks for the advice so far guys. My car is a 1994 Cadillac Deville 4.9 litre. To my suprise i started the cadillac up today after getting a new battery for it and it fired right up to problem it ran and i drove it to schucks to get some oil. Now it wont run or start at all. Im so confused, i tested the codes and it came up with 12-No Distributer Signal and 52-Engine Control Module Reset.
Does that mean i need a new distributer or could it be the coil or anything causing it do that. Any suggestions please i need help. Thanks In Advance.
