Remove Your Air Filter, If You See A Liquid Squirt or bubble up, Or smell gas, then its the plugs

What is the problem? Why are you limiting the problem to those 2 areas of concern?

If it is the electronic fuel pump that is the problem you will not hear the fuel pump humm as you turn the key in the ignition. Replace the fuel pump which is located inside the gas tank.

after you have replace the pump and it doesn't humm what else could be the problem

the fuel pump could still humm but it could be weak. there is a pressure valve on the fuel line behind the intake. put a pressure tester on it. if it is over 45 lbs. then your fuel pump is ok.

How do you tell if fuel pump relay is out?

The fuel pump will not come on. Of course this could be a blown fuse or the pump itself has failed. Check the fuse and if it is good then install a new relay to see if that solves the problem. If not the pump is bad.

1987 crown Victoria new fuel pump wont pump fuel can you tell me what the problem is?

Problem could be one of many things. First and foremost is the intertia switch. Check the fuel pump inertia switch (in trunk mounted to driver side trunk arm) to make sure its not kicked. If the problem is not there, than either the fuel pump relay is bad or there is a bad wiring connection in the circuit.
