No...Full power.. - ZR-1 Net Registry Forums

Hi...newbie ZR-1 owner here.

Just bought a 90' Z with 48K miles. I bought the car knowing that there was a leak to the secondary system. Read up on all the forums including this one about the system and how to diagnose to problem. Pulled the plenum and sure enough one of the hoses was disconnected. Hooked every thing up, even changed the wires while I was down there. Put everything back together, system now holds vacume and the pump is quiet with the ignition on. (unlike before) SES light is now out. Full Power light comes on when the key is turned.

Problem is...still no secondaries.

I know there are certain other engine parameters that must be met before the secondaries kick in. But with out codes and the SES light I'm not sure where to look.

Any thoughts, help or similar experiances would be appreciated.

Hans
