Question edited for clarity and make some real sentences and punctuation. Change 'want' (a request for something) to 'won't' (a contraction of 'will not). So many Americans get this wrong!
It is a Chevy, and it is 24 years old. When was it last serviced? Check spark plugs for gap and condition. Check compression. Also check transmission fluid level if by 'she won't move', you mean when you put the car into gear, it doesn't move. That could also indicate sticking transmission solenoids which free up as the engine oils and ATF get warm.

This is the stock wiring. Sometimes you need a conversion wiring harness to whatever aftermarket radio you are fitting. Crutchfield does them. The first this to try is bench testing the radio, with power, ground and one speaker, especially if it is not new.
Question edited for a lot more clarity.
Question moved to model category.
It might be the flasher relay and it might be the horn relay although horns tend to seize up through lack of use. the flasher relay is is separate to the Hazards relay which is often part of the switch.

Trouble Code 42 indicates that there may be a malfunction in the
Electronic Spark Timing (EST) system. During cranking, the timing is
controlled by the ignition module and the ECM grounds the EST line. It
expects to see no activity on this line at this time. When the ECM
enters EST mode, it applies +5 volts to the BYPASS line and expects to
see voltage variations on the EST line. Reasons for the ECM to set Code 42: 1. System in BYPASS mode (i.e. EST line supposedly grounded) but activity sensed on EST line 2. System in EST mode (i.e. BYPASS line driven with +5 volts) but no activity seen on the EST line
Possible causes include: 1. BYPASS line is open or grounded 2. EST line is open or grounded 3. Poor connections between ignition module and ECM 4. Poor routing of EST harness and/or poor quality ignition wires (EMI induced electrical noise 5. Faulty or incorrect ignition module 6. Faulty ECM 7. Faulty Pick Up Coil 8. Faulty Ignition Control Module
9. Faulty Crank Sensor or the Crank Sensor magnet probe could be cracked
Irrevocable damage on a vehicle that age. Cracked piston, broken or seized rings, stuck valves, cracked head. damaged bearings. The list is long. The first thing to do is use a stethoscope and trace exactly where the tapping is coming from?
You mean you want us to post 200 pages of wiring diagrams? Ain't gonna happen. That's just not the way it's done. See this post on how to get a wiring diagram.

If cleaning the injectors got it running and not it won't start I'd look at something contaminating the injectors, try recleaning again and see if it starts, if it does clean the fuel system
Cruise Control Cable
Disconnect the cruise control cable at the module and the throttle lever. Refer to Cruise Control Cable Replacement .
Ensure the cruise control cable moves in and out of the cruise control cable casing freely and smoothly.
Replace sticking or binding cables. Refer to Cruise Control Cable Replacement .
Replace the cable(s) if the adjuster lock does not hold under normal operating conditions. Refer to Cruise Control Cable Replacement .
This is the part that fails most, like in the video above.
Turn the ignition switch on.
Set cruise control switch to ON.
The cruise control switch indicator lamp turns on.
Does the lamp turn on?
Cruise Control System Circuit Description
The stepper motor cruise control (SMCC) is a speed control system which maintains a desired vehicle speed under normal driving conditions. However, steep grades may cause variations in the selected speeds. The system has the following settings:
• CRUISE
• COAST
• RESUME SPEED
• ACCELERATE
• TAP-UP
• TAP-DOWN
The cruise control module contains an electronic controller and an electric motor. The controller monitors the speed of the vehicle and operates the motor. In response, the motor moves a connecting strap that is attached to the cruise control cable. The cable moves the throttle linkage which varies the throttle position and maintains the desired cruise speed. The cruise control module contains a low speed limit which prevents engagement of the system below a minimum speed, approximately 25 mph.
The mode control switches are located on the multi-function turn signal lever. Cruise control is in Standby Disabled mode until all conditions which are inconsistent with cruise control operation are cleared.
With the ignition switch in RUN, battery voltage applies to terminal F of the cruise control module. When you move the slider switch to the ON position, battery voltage applies to terminal A of the cruise control module connector. If the driver of the vehicle does not depress the brake pedal, battery voltage is present at module terminal D. When the driver depresses the brake pedal, battery voltage is present at module terminal G. Terminal G must see current flow through the center high mounted stop lamp bulbs in order for cruise to operate (disable) properly.
When the driver moves the slider switch to the R/A position, battery voltage applies to terminal C of the module. With the Set switch pressed, battery voltage is present at module terminal B.
Cruise control module connector terminal K is the speed signal terminal. In operation, voltage will oscillate between a high of 4 to 5 volts and low of near ground. Cruise Control Module terminal E is ground.
Terminal J signals the PCM when cruise control is engaged. The PCM determines the correct shift pattern for the transmission.
The PCM uses terminal H in order to inhibit cruise control when any of the following conditions, which are inconsistent with cruse operation, occur:
• Vehicle speed is less than 25 mph
• When the park/neutral position (PNP) switch indicates the following gears:
- PARK
- REVERSE
- NEUTRAL
- 1ST GEAR
• When an under battery condition or an over battery condition exists
• With low engine RPM
• With high engine RPM (fuel cut-off)
If the signals come on, but don't flash, check & or replace your flasher, or swap it with hazard flasher if it's the same to confirm flasher is the problem. Hazard & blinkers are on serarate flashers.
