SOURCE: where's the fuel filter on a 2003 cadillac cts

The fuel filter on these vehicles is attached to the underbody, in front of the fuel tank. Note that there are no service intervals for in-line fuel filter replacement. Only replace the filter if performance problems or troubleshooting indicates the filter is restricted.

Hope this help (remember rated this post).

2003 Cadillac CTS how to do a hard reset please?

You can effect an ECM reset by disconnecting the battery for 10 minutes. HOWEVER, then you have to reset the antitheft and alarm security system. You will need the code for your radio, and you will need to a full Drive Cycle relearn.

and after that it still might not work. You really need a mobile auto electrician with a pro grade scan tool computer. You issue is electronic, not mechanical.

How do I reset the fuel gauge on a 2003 Cadillac cts

You take it to a qualified repair shop , no reset . They will hook up a factory scan tool an check fuel level sensor input data to the PCM- engine computer an input to instrument cluster . The sending unit in the fuel tank could be bad or the instrument cluster gauge is . GM had problems with stepper motors inside the instrument cluster , these stepper motors control the gauge ,fuel , temp , etc... 2003 to 2006

Just purchased a 2003 cadillac cts the fuel gauge does not work thought it was out of fuel ---filled the car up still does not work

The fuel sender is in the gas tank. If the gauge stays on empty then the sender may be bad . If the gauge reads anything else the wire between the sender and gauge is open. A bad sender can also give the same indication.

CTS 2009 Reset, recurring of fuel gauge and engine light issue ?

I would first try to do a hard reset which means disconnecting your battery for 24 hours, that solves more problems than you would imagine.
Good luck.

2004 cadillac cts gas gauge stuck reading zero

The reason the guage is staying at empty is because it has set a code for a fuel level sensor. This car has 2 so it could be either one, or a wiring issue (unlikely). When you disconnect the battery, you likely either clear the code or reset it as not current so it allows the gauge to work for a short time until the code sets again. Have it scanned and I am sure you will find a code likely P2066 or P2068 for the level sensors.

I have a 2003 Cadillac cts it drives fine but if im at a red light I shuts down but not all the time

Sounds like a possible fuel filter. Bigger question - when was last tune up? With the different grades of fuel these days and with temps fluctuating a fuel filter would be my first thing to change.

I have an cadillac Cts 2003 with starting problems

the plugs are the problem, they become unable to ignite all the fuel when in idle, so that they get wet and won't give any spark until dry. try to replace them. if there's no difference the problem is at the admission system(fuel pump maybe)
