Check your spark plugs, are they soaked with gas? Check for external gas leak, under the vehicle, under the hood, fuel lines, injector/s, fuel pressure regulator where applicable. Check your evap system.
Have a helper crank it while you visually check for spark at the plugs. How long since a tune-up? Any applicable trouble codes?
Yes there is a sock on the pump. You may also have gunk or varnish built up inside the fuel pressure regulator. make sure you have the correct fuel pressure at the fuel rail. Also check for a vacuum after the Mass Air Flow sensor. Once the engine is in gear the engine will shift slightly. if there is vacuum leak after the MAF sensor it will cause an engine to stall.
First check your fuel pressure regulator by pulling the vacuum line off and check for fuel there should not be any.Then start the car and with a pressure gauge hooked up to fuel rail pull the vacuum line off the pressure should rise 5-10 psi if it does'nt replace regulator.Next check the fuel pressure it should be 41-47 with key on and engine off if not within specs replace fuel pump.
Do a quick check. Run a wire passed everything from the battery positive terminal to the power connector on the pump, or if you cant get to the pump directly then the first connection you can make to the pump's power supply wire. If she fires up then its a bad fuse, faulty relay or something electronic not putting the power through. If she still refuses to fire it could be the fuel filter filter (to lean), leaking fuel regulator or leaking injectors (too rich). the regulator has a vacuum line on it. If there is a leak in the regulator then fuel vapour is carried by the vacuum line and enriches the air in the intake manifold. The fuel pump has to deliver about 40 - 50 pounds of pressure to the fuel line and has to keep about 90% of that pressure for about 5 minutes after it has been switched off. Dropping pressure indicates poor valves on the pump or leaking injectors. It is not enough that the pump is effective the fuel line should be capable of filling a pint pot in about 15 seconds. If the pump has good pressure (and retention when off) but poor flow then the filter is clogged (this will also kill the pump eventually). As a final check make sure the idle air control valve on the throttle body is clean and functioning as it should.
IF FUEL FILTER HAS BEEN REPLACED.FUEL PRESSURE REGULATOR IS GOING BAD OR NOT GETTING VACUUM.CHECK VACUUM LINE GOING TO FUEL PRESSURE REGULATOR.MAKE SURE ITS GETTING VACUUM.IF YOU SEE GAS IN VACUUM LINE TO REGULATOR.REPLACE FUEL PRESSURE REGULATOR.IF ALL IS GOOD FUEL PUMP GOING BAD.
It sounds like a faulty fuel pressure regulator. When you turn the key to the on position the fuel pump starts for an instant to build pressure in the fuel line. If the pressure regulator has allowed too much leakage since the last start then the fuel pump does not have enough time to prime the line. The fuel pressure will still measure ok when the car is running because the leakage is very low. Try turning the key off and on a few times prior to starting and see if the extra pump priming steps help. Also check the vacuum line to the regulator because it needs vacuum to work correctly.
