Even though the KE system doesn't have an accelerator pump, pumping the throttle will actually add additional fuel if the engine is running because of the mechanical connection between the air flow plate and fuel meter.

Is the ABS light on? Assuming this is a cold start issue, it could be an OVP problem since the the OVP provides power to the KE and ABS electronics. OVP relays are known to act "flaky" due to intenal bad solder joints.

If there is no power to the KE system, none of the cold start features are active, so the car can be hard if not impossible to cold start.
