Second, on the pedal assemblies you have the switches for Start, Brake, and Cruise release.
Verify that all switches are adjusted properly.
On the brake pedal, you will have two switches. Both switches are activated when the brake pedal is pushed down. The activation occurs when the button on the switch is released.
To properly adjust the switches, firmly push the switches TOWARDS the brake pedal. They will complain a bit by clicking, but they should stop dead against the pedal. The clutch side has a switch that PULLS a rod through the center of the switch. It has a small plastic clip on the side towards the driver that adjusts. When you push the clutch pedal, it pulls the road, which slides through the center of the switch. This pulls the plastic clip down, and engages the switch, allowing you to start the car. If this is out of adjustment, you will be unable to start the car. I believe there is a second switch, either part of this assembly (been too long since I checked), or near it that also disengages the cruise when pressing the clutch pedal. It operates similar to the brake switch, if it is not part of the main start switch.
Verify the electrical connections on all switches. Pull the lower trim under the dash. Look for a black, very stiff wire coming out of the column. It will end in a flat connector that plugs into a 4 wire plug. This is your cruise switch. Verify it is connected properly.
Under the decklid, check the connections on your vacuum servo. The canister under the vacuum servo is a vacuum can. They tend to develop pinholes in them. Check it for rust. If clean, then move on.
Check your vacuum lines from the servo to the engine, and from the servo to the vacuum canister.
90% of Cruise issues are caused by the switches at the pedals.
The cruise computer sits in the left side of the center console, down by your right foot/leg. It is clipped into the plastic panel behind the carpet.
It receives the speed information from the dash cluster through a plug on the bottom of the left side of the cluster. Verify this is plugged in when the lower trim panel is removed.

Disconnect it, plug the lines and throw it away. Your engine compartment instantly looks enormous.
Not me. I make sure it works. I use mine all the time. My daughter's coupe doesn't have it and I'm putting the pieces together to put one on. When you drive an average of 400-500 miles everyday you really learn to appreciate cruise control anytime it's available.
Synthesis is right those are all good things to check. Another problem area is the cruise switch itself. On my car, the wire broke where it enters the turn signal stalk. With some luck, I was able to disassemble the switch, cut off & unsolder the broken wires and resolder the remaining good wires to the switch.
