starter is located behind the motor under the intake manifold, to replace remove the battery cable & air filter box and remove 2 15mm bolts that go through the bell housing into the starter then get under the car and remove 4 10mm nuts & bolts that attach a plate from intake to the block then remove 1 more 15mm bolt holding starter in and pull it back then nose first down then remove 10mm and 13mm nuts on starter solonoid removing cable and wiggle it out past the half shaft and vualla its out

Two common things can cause this code. High fuel pressure or a bad fuel pressure sensor. The easiest thing you can do is replace the sensor. It is located on the fuel rail on the passenger side of the engine. It will have a vacuum hose and a connector plugged into it. The part is available from the dealer for about a $100. A basic set of tools and about 1/2 hour are all that is needed to replace.
The fuel line will be under pressure so be aware that fuel will spray all over the place when you remove the sensor. There should be a test port near the sensor with a black plastic cap. If you remove the cap you will be able to push in the schrader valve and release the pressure. Again watch yourself and have some rags handy to catch the fuel spray that comes out of the test port.

SOURCE: getting p0193 code for my
P0193 is "Fuel Rail Pressure Sensor Circuit High Input"
Meaning: Car's computer is reading input voltage from the FRP (Fuel Rail Pressure) sensor as
voltage out of the acceptable range, because the voltage is too above the acceptable range.
assuming you are running gasoline...
check for fuel in the vacuum hose of the FRP sensor after running engine at idle for 2 minutes. if not, check fuel pressure. Check fuel pressure by connecting a fuel pressure gauge to the Schrader
connector on the fuel rail, which you will find under a small (black, usually) plastic protective cap.
If the fuel pressure is indeed too high, your fuel pressure regulator has gone bad.
if fuel pressure is good, check voltage between Sensor connector Vref (Pin#3 LB (light blue)) and
Signal Return (Pin#4 GY/RD (gray/red)), which should be 4.0V-5.5V with key ON.
The acceptable voltage range from the FRP sensor to the car's computer is 4.0-5.5 volts.
What the P0193 code is saying is that the voltage from the FRP sensor is over 5.5 volts,
and therefore it's "High Input."
If voltage from the FRP sensor is bad (out of range high, presumably), then replace the FRP
sensor and reset the OBD-II code.
If the voltage output from the FRP sensor is also good, the car's computer is kaflooey, so
you'd need to replace the car computer (which is costly), so replace the car's computer as a
