change fuel filter.then check fuel pressure.if you got TBI FUEL INJECTION PRESSURE SHOULD BE 26-32 PSI. IF YOU GOT MFI FUEL INJECTION PRESSURE SHOULD BE 40-47 PSI.if all is good .have car scan check the egr valve.map sensor. coolant sensor.if any one of those are bad it causes rich fuel mixture.that will cause you to fail smog test.also replace plugs and wires.if they are faulty they will misfire cause unburn fuel to come out exhaust.also check for for intake leaks check all vacuum hoses.

No, the water pump leak would not cause it to fail the smog test. The only way that could have any bearing on the test results, would be if you lost a lot of coolant, and the car was overheating, then maybe it would have something to do with failing. What were the results (specific #;s and exactly what failed?) Is the check engine light on?

No this is not right. If you remove the battery everything resets anyways. If they are talking about relearn procedure, it should only require 50 miles. But if the light is on than either they did something wrong, created another problem, or there was already another one existing. Have the code read and let me know what it is. I'm in Ca too and used to prep european cars for smog, so I do know what I'm looking for. How did the rest do? What were the readings(if possible)?
