Why / how do you feel scammed?

Why was the pump changed?

Did you test the wiring for power prior to changing the pump?

Did you test the wiring for power after the pump change?

Did you apply 12V to the clutch to see if it engages?

My 97 has a electric air pump. It typically runs for 60 sec at start up to provide extra oxygen to the exhaust and sometimes runs for a few seconds after coming to a stop.

Also, most have a upshift delay when cold to get the car converters warmed up.
