I have 1994 chevy silverado. Cruise control

There are some ideas in the link, but because of the Cruise Control issue, I think you need an auto electrician as things like this are controlled by ECM and BCM.

Look for a bad ground connection.

Could be a relay. Look at your wiring diagram. Swap relay with one of the same number, see if it cures the problem.

If the switch is replaced,then it can be wiring issue or faulty cruise control board.But as the switch is replaced,get the voltage at the switch tested to confirm the switch is actually receiving voltage.If no voltage received at switch power supply wire then ,apply external 12 volt power to the cruise control switch wire and then see if cruise control comes ON.If yes,then you know wiring is issue.

It sounds like the cruise control linkage was never reconnected. Have you been back to the place that did the work?

its the fuel cut off valve locate on top of the fuel injector pump. shape like cylinder
to test it remove it from the pump.plug back wire turn the key on.but (don;t start) the black rubbber should pull back. if not it broke.Auto sale $278.00
Ebay $89.00

check for a vacuum leak i believe the cruise control runs off a vacuum
