On the engine there is a tube that supplies fuel to the fuel injectors, on that tube there is a valve, like a metal tire valve, this is the fuel pressure test port, you will need a special guage to check the pressure that screws onto that valve, Kragen and other parts stores sell this test kit, it is very inexpensive, about $20.00, but cheaper than having a shop do it for you, if you do the test and you have no pressure while cranking the engine then your fuel pump is bad, the pump is in the gas tank, a big job and dangerous due to chance of fire if you are not cautious.

The car will take 6 quartz of oil.

The theft light blinking indicates a PATS (perimeter anti-theft concern.It means that the computer has not recieved a signal from your key when trying to start the vehicle. A few things could be wrong.
1...The key you are using to start the vehicle is not programmed to the vehicle or broken internally. So try a different key(one that you know is programmed to the vehicle) if you have more than 1. If the theft light goes on and flashes when you try to start the vehicle, you must wait about 5 minutes before trying the second key because the computer goes into antiscan or theft mode and wont let any keys start the vehicle.
2... There is a small transciever ring located arount the key cylinder which recieves the key signal. The wiring for the tranciever runs down the steering column into the dashboard wiring. Sometimes these wires break. If you have a tilt steering wheel, move it all the way down and try to start, then try moving it all the way up and try to start. Keep in mind the antiscan that I mentioned in #1. If this works then you need to check the wiring at the base of the steering column. A white connector with 4 wires. Pull on each wire to see if any are broken.
3... Check fuse #30 on interior fuse panel. If it is blown then you will have to trace down the cause of the short. The ignition coils are on this fuse also so one could be shorted. Disconnect all ignition coils(you may have 8 located on each plug if 5.4l engine or 2 located on l+r front of engine if 4.6l engine) and see if the short is gone. If the short is still present disconnect the radio noise supression capacitors( small black box approx 1" x 1" square with a single wire coming out) that are located on the left and right front of the engine. Pay close attention to all the wiring around the coils, look for any areas that may have rubbed thru and shorted.
These are things that I would look for first and are the most likely causes. This should get you started in the right direction. Be patient and post your findings if you fix it or not.
Good luck
