    Please help, won't start
    Was driving and randomly stopped. No warning no nothing. Pulled over tried starting and it wanted to turn over but wouldn't. Let it sit for about 10 mins and it started up like normal. After letting it run for about 5 mins it shut off exactly the same way. It won't ...

      Have you done any testing? When problem is ongoing, if it cranks good but won't start, Have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Last, but not least, check for a fuel injector pulse. It may be possible to have spark and good fuel, but, if the computer doesn't see an rpm signal, no injector pulse/ground, even if you have the other two. I haven't looked at your vehicle information, yet. My first thought is your losing rpm signal or something wrong with ignition module? I can't be certain from here.

      Can you check for applicable trouble codes? Your obd1, you should be able to check some codes, yourself.

      I did check the battery now and that's not it. And I can't check the codes with an OBD reader due to the fact I don't have one and my cars in the driveway unable to get someone to text it. But I did contact autozone and they think it's the ignition module but I don't see how it could be that cause the car starts up and runs but then dies

      Your obd1, you don't need a code reader. You can use a jumper wire between terminals A & B at the data link connector. Then turn key just till the dash lites, come on, no further. Then the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes.

      My bad, some of my info says, no way to use flash codes. Sorry about that, I'll double check.

    Why does OBD2 reader say no link?
    It died while idling at stop light & would not restart. It cranks but no start. OBD2 reader says no link when hooked up.

      At the datalink connector, check pin 16 for voltage, if no voltage the code reader won't work. Of course there could be other issues? Pins 4 and 5 are grounds.

      You may have to check serial data lines?

      A mechanic said something is shorting out my computer, but he will reprogram computer for $280. But when I asked him what was shorting it out, he said he didn't know.

      How do I flash the ECM? How much does it cost to reprogram a used ECM?

      Call different shops and get estimates. I don't know if this would be a dealer only type job? I guess anybody with the proper access and equipment can do it?

    My car is shooting out clouds of smoke and smells like burnt rubber.
    My car was leaking oil from the oil pan. We got it fixed. Then we noticed the valve cover was leaking so we changed that too. I only put a quart of oil in it at that time. Today i added 3 quarts and now there are clouds of smoke coming from the tailpipe. And it ...

      Did you fill up the tank? Use a gage and check proper fuel pressure. Also, check for a fuel injector pulse.

      If the problem is gas, cycling the key two or three times before you crank it may help?

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance.

      This aspect is important; there may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      Do not skip this important first step - there are literally hundreds of possible fault codes. Avoid wasting/ throwing money at the problem.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

    Why does my car die out when it gets warmed up?
    My car runs fine until it gets warmed up and then you can smell antifreeze and it'll die out while driving. We usually have to double foot it after it gets warmed up to try and prevent it from dying and that doesn't always work. Sometimes we can start it right back ...
