which engine is it. and USA car?
did you even look first. seems not to me.
why not go to Valvoline oil changers, and let them do the mess.
no split oil.
here it is, me reading your manual < LOST IT:
?
Question edited for clarity
Take it to a good local auto-electrician as advised.

Have it checked for DTC'S - diagnostic trouble codes , before you start playing with thing's . All the gauge setting information comes to the instrument cluster over serial data network GM Class 2 from the PCM/ECM engine computer . Could have U codes stored, Do you know anything about serial data networks or U codes ? If not, do yourself a favor an have a qualified repair shop check it.

Fuel Gauge
The instrument panel cluster (IPC) displays the fuel level based on information from the engine control module (ECM). The engine control module (ECM) calculates the fuel level based on information from the fuel level sensor. The engine control module (ECM) sends the fuel level information to the body control module (BCM) via the serial data circuit. The instrument panel cluster (IPC) displays the fuel level as received from the BCM. The fuel gage defaults to E (empty) if:
• The ECM detects a malfunction in the fuel level sensor circuit.
• The IPC detects a loss of serial data communications with the BCM.
• The BCM detects a loss of serial data communications with the ECM.
When the fuel level is less than a pre-determined value, the Low Fuel indicator message illuminates.
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on information from the engine control module (ECM). The engine control module (ECM) calculates the vehicle speed from the vehicle speed sensor (VSS) input. The ECM sends a serial data message to the BCM indicating the vehicle speed. The instrument panel cluster (IPC) displays the vehicle speed as received from the BCM via serial data circuit.
The speedometer defaults to 0 km/h (0 mph) when any of the following occur:
• The ECM detects a malfunction in the vehicle speed sensor.
• The BCM detects a loss of serial data communications with the ECM.
• The IPC detects a loss of serial data communications with the BCM.
The plug cables could be worn. You can't tell from surface inspect or test each one. The boots or connection is common to wear. Also ignition module may have issue. The timing or fuel delivery may be hidden problem
The models ran from 2002 to 2007 as the first generation and 2008 to 2010 as the second generation. So there is a good chance the CD player will fit.
The only thing to watch for is if there was a factory option upgrade to the head unit. This could affect wiring.
As long as the two units look exactly the same and you've got the unlock code you should be able to fit and use it.
Hi. Thanks for your question. For assistance on intermittent starting issues you can visit https://www.reliable-store.com and download the entire workshop manual which includes all the information along with the diagrams for better understanding. Good day!
What
Dealership ?????? Saturn dealers are no more . What is it you would like to know ? Complex electronic's involved . Ignition switch is low voltage input to the BCM - body control module.
Have seen this problem your having before , BCM problem ! Service engine light on ????? What DTC'S - diagnostic trouble code's are stored , same for air bags an
Traction control "OFF"
What code's . Any code's stored in any module ? Do a full vehicle scan .
The body control system consists of the body control module (BCM), communications, and various input and outputs. Some inputs, outputs and messages require other modules to interact with the BCM. The BCM also has discrete input and output terminals to control the vehicle body functions. The BCM is wired to the GMLAN High speed serial data buss and the GMLAN Low speed serial data buss and acts as a gateway between them. If the BCM does not communicate the vehicle will not start due to the inability of the engine/powertrain control module (ECM/PCM) and vehicle theft deterrent (VTD) control module to communicate without the BCM providing the gateway function.
Power Mode Master
This vehicles BCM functions as the power mode master (PMM). The ignition switch is a low current switch with multiple discrete ignition switch signals to the PMM for determination the power mode that will be sent over the serial data circuits to the other modules that need this information, and so the PMM will activate relays and other direct outputs of the PMM as needed. Refer to Power Mode Description and Operation for a complete description of power mode functions.
Your best bet , try a different dealer .
My guess is, it is telling you the horn relay is absent/defective? Put the relay back. It may be the relay is the problem or maybe not. Look for a code.
have vehicle scanned if their are any codes pending or active remote start wont work --also may have lost program with fob which a dealer will need to flash
