Emmissions failed due to the following. OBD Connector Integrity - malfunction indicator light (MIL) status This is for a 2000 chevy lumina

That means the check engine light is on.

you need to check the bulb in the dash see if its good check for power at the plug for the obd

MIL is your malfunction indicator lamp, (check engine light)

CMD is the computer interface port, or OBDII port indicating a malfunction communicating with your cars computer

check all the fuses, primarily any marked pcm and retest your vehicle
note: your check engine or MIL has to be on in KOEO state (key on engine off), if the bulb is burned out everything will still work and the OBDII test computer will show MIL status ON, and if you don't have a computer to tell you that, you must get that light to light in the koeo state.

obd is the diagnosis connector, mil is malfunction indicator light, also known as check engine light

First step is to have the code or codes read.If the "check engine light" is on there will be a reason and should be a code or codes to be read.Once you have the codes,you can determine the correction needed to get that "check engine light" out and a valid emissions test completed.Get back to us with the codes found.

could be a fuse or a broken wire

Doesn't look like an easy fix? Good luck.
Potential Symptoms

There will likely be no noticeable symptoms along with this code other than the MIL (Malfunction Indicator Lamp), commonly known as Check Engine Light illumination. However, there may be noticeable fuel odors in some cases.
Causes

A P0453 DTC trouble code may be caused by one or more of the following:

• Open on FTP sensor signal wire
• Short to voltage on FTP sensor signal wire
• Bad FTP sensor
• Abnormally high pressure in fuel tank due to blockage in EVAP purge hoses or overfilled tank
• Loose/damaged FTP sensor connector
• Loss of ground to the sensor

check the connector on some chevys they go bad i have replaced them before so try a new connector or maybe that the wire got burned with the exaust pipe or even disconnected ?? good luck.

Trouble Code: P1676 (3.8L V6 VIN K Auto)
Evaporative Emission (EVAP) Purge Solenoid

Number of Trips to Set Code: 1
OBD II Monitor Type: CCM Details
Indicators: MIL Details

• PCM Details
• MIL Details

Trouble Code Conditions:
Conditions for Setting the DTC.

• The ignition is on.
  
• An improper voltage level has been detected on the output circuit which controls the EVAP purge solenoid.
  
• The above conditions are present for at least 30 seconds.
  

Possible Causes:

• Poor connection at the PCM. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.
  
• Damaged harness.
  
• Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the PCM, turn the ignition on and observe a voltmeter connected between the EVAP purge solenoid control circuit and ground at the PCM harness connector while moving connectors and wiring harnesses related to the EVAP purge solenoid. A change in voltage will indicate the location of the malfunction.
  

1998 Chevrolet Lumina - Powertrain - Engine Controls - 3.8L - DTC P1676 Evaporative Emission (EVAP) Purge Solenoid Control Circuit

Some vehicles require very specific drive cycles (called "drive traces" if you perform them on a road simulator or dyno) to activate certain self-checks like the catalyst and EVAP monitors. As a general rule, doing some stop-and-go driving around town at speeds up to about 30 mph followed by five to seven minutes of steady 55 mph highway speed driving will usually set most or all of the monitors. Consequently, if you're checking an OBD II system and discover that one or more of the monitors have not run, it may be necessary to test drive the vehicle to set the remaining monitors.

You should talk to a good emission tec, if this is not throwing a code, it is hard to say if that one of the components could be bad. O2,pump,convert, HeO2, every part of the emission system.

With a 1000 miles, and doing what is says above just before the test, and ending driving at the test
should be plenty. If it is not, you will have to have each emission part checked, or when the computer
is plugged in it might show a code that did not trip dash light.
