The fuel filter is under the car in the rear on the right side of the fuel tank.

Possibly the ignition switch.

Check the passenger side tire.

Check the wire connection at the starter and make certain they are tight as the power supply to engine and accessories is picked up there at the solenoid. Check the engine ground strap as well.

Are you gettiing power to the starter when you try to start it? If not,....more than likely its a relay or wiring issue.

I would not worry about the pressure you are seeing. Cold oil will have a higher pressure and drop as it get warm. Also newer cars run lighter weight oil in an effort to get better gas mileage. You can run heavier weight oil if the lower pressure bothers you and as the mileage goes up on a car things wear and the pressure will drop.

Windshield wiper motors are generally easy to replace. You need to remove the windshield wipers and take off the small grill panel above the hood and under the windshield. You should see the motor in there. It simply unbolts and unplug the electrical connector and replace it with a new one.

Hi Jason: When you take the oil filler cap off, you allow the crankcase to vent through that space. The PCV valve normally attends to the function of neutralizing the crankcase pressure differences. Not knowing what electronic monitoring and controls are on your car, I would stick to the "If it ain't broke, don't fix it" routine. Just a thought, if the pcv is on the cap, and you turned it upside down, there's your vacuum leak1

1 fuse 1 relay 1 fuel pump that realy hates when you run it out of gas. open gas door remove cap have someone listen to hear pump "whine" when you turn key on . give fuel tank a good whack this may work 1 time (seen many no starts that when tow truck brings them in i go out and driveinto shop then wont go again) you gotta drop tank to test for power grey wire to pump

Check for a large plate in the trunk it could be in the tank if not in the fuel line.

Yes with a engine adapter

In the fuel line back by the gas tank on the passengers side of the car just in front of the rear wheel.

Well Jeff if you think it is flooded I'd start by pulling the spark plugs and see if they are wet with fuel . If they are clean them or replace them. If not wet , I would check for fuel pressure , you can get a fuel pressure gauge at harbor freight fairly cheep. On the fuel rail there is a black cap, un screw it an screw the pressure gauge on to it. Crank the engine over a few times an see what the pressure is, it should be 55 psi. And if you have fuel pressure check for spark, pull off a plug wire and put in a spark test , you can buy one at harbor freight or auto parts store for $5-$10 .If it has spark you would need to do a compression test. You can get one of those for $30 bucks .How many miles does the car have . What engine ? 3800 V-6 this engine should have the timing chain replaced at 150,000 miles . have seen them jump time causing them to die and not restart. Should have 150 to 175 psi compression depending on the ware on the engine. Last one I did when the timing jumped , it bent an exhaust valve .

Under the left of the IP, near the IP fuse box Instrument Panel-IP

Check the alternator to see if it's charging the battery. If the battery is approaching 3 years old then replace the battery.

Look at all the hose connections. The leaking one will be wet with fluid and will attract a lot of road dirt. Usually a loose clamp will cause the leak.

Not enough information. Cannot diagnose problem without inspecting or having more information on what exactly the system is not doing.

Blower relay stuck

Try getting the brake pads replaced.
