Replace ignition module. Engine computer is related only to the fuel injectors. Spark is only controlled by ignition module. Make sure that you replaced the prom chip inside the computer when you did your switch as well.

There is a loose connection on the sensor, or clean it with a fine Sandy paper, it's best to replace. If the problem persists, see a specialist.

Hi Ricky:
That could be a trick question as a lot of the older vehicles did not have a horn relay. This is where a bit of wire tracing will come in handy. If you find the horn(s) you can use a jumper wire from the batter positive terminal and touch the horn where the wire attaches. You'll know if the horn is functional.
- Having someone listen under the hood (engine off) while you press the horn button should make the solenoid click if there is one.
- check the fuse panel for a horn fuse, and make sure that there is power. If there is power at the downstream side of the fuse, check for power at the horn when the button is pressed.
- Have a ponder about how well the horn worked BEFORE the problem started, and ask yourself if anything specific happened that might have caused the problem.
Cheerfuls!

Check to see if you have power to the solenoid (on top of the starter). Connect power to the small wire on it for a second. Any results? Use a screwdriver to bridge the two large connection bolts on the end for a second. Sparks and engine turn over?

Probably lost either spark or fuel. First try some starting fluid into the throttle body (take off the big air boot) and see if the engine tries to run on it. If it does, you need to see if the fuel pump quit working. Best is to check fuel pressure-autozone and others rent or loan fuel pressure gauges. If pressure is not there with key on, likely a bad fuel pump. (you should hear the pump turn on for 2 seconds when turning the key to on, not start-this will pressurize the lines up to the fuel rail and to the injectors. Listen for the pump to turn on.)

If you have gas up to the engine, and the starting fluid caused nothing, check for spark. Buy a spark tester from a parts store and check for spark on 2 or 3 spark plug wires. If no spark, the ignition system went out. This is often due to the Crank Position Sensor or the Ignition Control Module.
