SOURCE: Failed AZ emmisions test

On the side of the dome shape intake manifold closest to the belts, there is either a sensor with a 3 wire plug going to it or just a vacuum hose (it depends on what engine you have in your car as some have the valve visible while others have it hidden). If you have the dome, remove it and you'll see something that looks like a lid. take the lid off and the pcv valve will be behind the lid

SOURCE: i need to reset the timing on my 93 oldsmobile

You must have an ignition distributor to be able to reset or change the engine timing. If you do have a coil pack then the engine timing is completely controlled by the computer and there is no timing adjustment.

What makes the fuel pump not kick on on a 92 Oldsmobile Cutlass


There is a red wire close to the battery in the front. It's not connected to anything. Apply positive voltage and that will run your pump for testing purposes.

Fail smog test


fist i would like you to post the year make and model of the truck along with the HC ppms and NOX ppm it would be very helpful but high hc and nox can be attributed to a faulty EGR system nox is produced when the combustion chamber temperature gets too high so a small amount of exhaust is cycled back into the air stream to help cool them there are other causes but without looking at the levels its much harder to say

My 1992 Cutlass Supreme SL Olds failed emissions.


High NOX readings indicate a somewhat lean condition IE: hot exhaust. Possible causes are cracked and leaking vacuum lines or lazy oxygen sensors. If possible have a reputable garage with engine electronics scanner services check the sensor to see if its helping to create the lean condition
