The fuel pump and sending unit is located in the tank. I hope your tank is empty, if not you will need to siphon it out. It is dangerous with the gasoline, and remember the fumes burn, not gas. You start by removing the filler hose, then loosen straps, detach sending unit wire and fuel line, then lower tank. Then unscrew the sending unit/pump and replace. reinstall.

E13-Oxygen sensor voltage stays between 0.307 and 0.609 volts for 64 seconds. Engine was at normal operating temperature at a speed over 800 RPM.
E44-Right oxygen sensor was lean for more than 50 seconds when engine was warm and at 800 RPM or greater.
E52-PCM has lost primary battery power.
E58-Pass Key fuel enable was not correct.
F47-PCM has received bad data from IPC for 3 seconds while engine speed was 500 RPM or more for 3 seconds.
F48-EGR open command was given during off idle operation. EGR opening should cause the mixture to be slightly richer because of the low oxygen content of exhaust gas. Vehicle speed was over 35 MPH and engine was warm.
Good luck and hope this helps, keep me posted be glad to answer any questions you may have.

The E98 is P/N to D/R In ISC (Idel Speed Control) Range problem. This code will not trigger a service light.
The F47 is Refrigerent System Problem. This code turns on the Service Air Cond light, and switched the Climate Control from Auto to Economy.

I've got an even cheaper and easier solution, instead of buying a new cylinder, find that plug and snip the orange wires going to the old cylinder.Then remove the resistor chip from the key and solder each of the the wires to each side. this will fool the car into thinking the correct resistor chip is in place, allowing you to use the original key or any copies with or without resistor chips. i just did this to my caddy and it roared to life! :)
