1- do you have aftermarket audio or alarm installed recently- if yes, that is likely the phantom drain.
2- if this just developed, does the fuel pump remain on? You can hear it running if kneel down by the gas tank. If so- relay may have fused contacts- in which case replace relay. Alternately the oil pressure switch may be stuck closed. in which case- replace the oil pressure switch- it is not the same one that controls the oil pressure gaauge or light- those are in a different location.
The Fuel tank pressure sensor or Fuel pressure sensor? The pressure sensor for the fuel line is located in the Engine compartment, although I don't have the exact location it is located on the fuel line. If your talking about the Fuel level sensor that is actually part of the Fuel pump assembly. You should pick up the Haynes Repair manual on your vehicle before attempting either repair.
Most mechanic shops would be able to check the fuel pressure coming from your fuel pump. Before you do that, try replacing your fuel filter. If your fuel filter has gotten clogged, there may be enough resistance to kill the motor. It is possible that you have some other obstruction in your fuel system, like a clogged fuel line that will also cause this problem.
Most vehicles other than Fords don't have fuel pump switches. You'll have to track this through the wiring harness...but I'd check the fuel relay first.
The sputtering...replace the ignition wires and plugs, then the coil pack. Still not...get to someone with an analyser. Water in the gas is rarely a problem today...the ethanol in the gas is almost the same stuff in the 'water remover'.
