I can't get an inspection sticker for my car because it keeps failing inspection because the computer will not reset. Every time it does the same thing. When they test the OBDII Readiness it says the...

Every time you reset the light or disconnect the battery it completely resets the system and it has to go through EVERY test again. The O2, EVAP, and Cat tests are generally the LAST THREE tests that are tested. You're not doing yourself any favors here.

Essentially what these readiness monitors are is the computer's notation that his has run the self diagnostics on each system and that the results feel into the expected results. If it is outside the expected results the computer will generally try to run the test multiple times before setting a DTC and turning on the Check Engine Light. It cannot set the status to "Ready" until it has a successful test within expected results; sometimes multiple successful tests. Sometimes, the tests need to run at different speeds - so the vehicle has to be driven not only at freeway speeds, but also city speeds for the tests to complete properly.

The O2 test MUST complete before the Catalyst test can run. The EVAP test generally requires that you have your fuel level at between 1/4 and 3/4 and that the vehicle sit undisturbed after being driven for a period of time for no less than 8 hours in order to run the EVAP test.

The same can be said for the O2 test sometimes because the computer needs to test the O2 sensors reaction to heating up and cooling down. Eventually they will all complete - unless there is an issue. I have seen where a component was in the process of going out and the computer was getting both GOOD and BAD results when running the tests. As a result it wouldn't set ready status because it wasn't getting the concurrent GOOD test results.

As a Texas Recognized Emissions Repair Facility - my shop sees this kind of stuff all the time.

Good Luck.

How many oms for the starter and fan relay on 1991 Cherokee Laredo

Starters are measured in the amps they draw under load (while turning the engine over). General rule of thumb is an amp per qubic inch of engine displacement. For instance, a Chevy 350 V-8 should pull about 350 amps cold cranking. A 150 cubic inch 4 cylinder should pull 150 amps. Disable the ignition system so the engine can not start during test. Ohms generally do not change except if there is an open curcuit (infinity ohms). You did not list the problem that is leading you to troubleshoot this way. If the starter is off the car, many parts houses (AutoZone) will test for free. Ray (garage owner)

How do I test a rear windshield wiper motor ? Generally it doesn't work at all. Sometimes the blade will move half way and then stop. With a helping hand it can be returned to the static position. All...

There two ways. One is dynamic testing, and the other is static testing. Dynamic testing simply means you put power to it to see if it runs. Static testing means measuring the resistance at the terminal, which you will need a multimeter. Dynamic testing just requires 12 volts source.

Mazda Tribute. Water leak under driver's feet. Had similar leak on passenger's side and it was the air-conditioning. Could this be the same?

Generally, water on the passenger side is the A/C drain tube.
Driver side generally means widshield or sun roof seal leak.
Did you wash the Mazda or did it rain prior to puddling?
Before disassembling the windshield seal, test ... with a water hose (Remove floormat and place a towel on newspapers on the driver's side floor).
There is a "smoke" test" that can more accurately find the leak. See if you local AutoZone will rent one (maybe free) to you.

Vw passat will not run

*Assuming everything ran fine prior to running out of petrol*, the most likely cause is air in your fuel lines or fuel injectors.

For a Volkswagen, the most sure fix is to have a Volkswagen mechanic inspect and maybe clean and prime your injectors. If you are handy enough, you could possibly do this yourself, but it can be quite hard.

Also, there are some additives that claim to be able to fix this in a bottle, but there efficacy is marginal at best.

Last, this problem can sometimes work itself out, though the process of waiting for the bubbles to clear (you may have to endure many quits by your engine) can be more than frustrating.

I hope this helps.
