After replacing front and rear brake pads, the pedal is spongy when engine is running. Good firm pedal with engine off.

Try bleeding your brakes thoroughly. Start with a caliper farthest away from the master cylinder and work your way closest. If that does not work you may have a master cylinder going bad

It sounds like you have air in the system, try bleeding it as described earlier. Also this vehicle may require a scan tool to do an automated bleeding of the abs module. If you can not get a better pedal with conventional bleeding you might have to take it to a shop or find someone with a scan tool that will do the bleeding.
