1994 Mercury Topaz 4cyl starts up for a few seconds, then stops, I did replace the Fuel Pump on 4/17/13 and I'm pretty sure the Fuel Pump assembly, that it had a new Fuel Pump Relay, not positive though....

swap your fuel pump relay with something like your horn relay but the relay is almost never the problem to check the fuel pump turn the key on and listen near the filler cap if the fuel pump buzzes the fuel pump will only buzz for 3 to 5 seconds check for fuel pressure at the fuel rail it could also be fuel filter stopped up or pressure regulator

Is there a trap door for a 1991 buick in estate station wagon 4 the fuel pump

No there is not. If the fuel pump needs to be replaced than the fuel tank will need to be dropped from the vehicle. This is a pretty easy tank to pull.

1989 Buick park Ave....I have replaced the fuel pump, which didn't make a noise when it stalled, so i assumed it was the pump,...i checked the old one and it works, i have the new pump...

Have you checked for voltage at all those locations you changed parts or checked?Have you checked for voltage back at the pump?Have you checked the ground for the fuel pump?Also,other than the priming cycle,fuel pump voltage runs through the oil pressure switch when the engine has oil pressure.
You could keep cranking the engine until you have oil pressure and the pump may just start on that circuit,

Not starting after replacing fuel filter and tune-up

I had the same problem with a 1989 Volvo 740 GLE station wagon. I did the same thing you did. But this time I talked to the local Independent Volvo service shop, not the dealer. The problem turn out to a bad fuel pump in the gas tank. You can replace it from inside the back of the station wagon. Just remove the floor panel to access the top of the fuel tank. But before you do; note that there are two fuel pumps, one inline underneath the car on the drivers side, and the one inside the gas tank. Before, you replace any of the fuel pumps check the fuel pump relay behind the astray on the left side. It could also be a bad relay.
