On my 88 560sel -I changed the smog pump and the two valves that go to it. Are you sure these valves are good (if your car has them?). On my car there is a plug for the smog pump clutch on the passenger fender inside wall. If you have the same plug - unplug it and hook up a voltmeter to the leads from the car. When someone starts the car - read the meter - you will know if voltage is getting to your pump.
