      The check engine light doesn't have to be ON to store a fault code.

      Check the vehicle for fault codes to see if there are any sensors were involved to the malfunction of the engine.

      1.Local auto parts stores such as Autozone ( not in California) or Advance Auto parts will scan and retrieve any diagnostic trouble codes ( dtc ) stored in the powertrain control module for free of charge..

      2. Amazon.com has the code reader for less than $ 18.00 dollars + shipping
      Autel MaxiScan MS300 CAN Diagnostic Scan Tool for OBDII Vehicles

      3.Re-post the dtc's in here " answer question " for further assistance.

      Note: we need the dtc's to identify the sensor, there are a dozen different sensors to operate the car.

      Visit this site and see all the different sensors.

      Have your battery tested at any local shop for free. If it passes, your problem may be due to loose/corroded connections at the battery terminals and/or starter motor and relay. Any green-bluish growth around connections is a buildup of corrosion and needs cleaning.

      If the starter motor does not have enough power supply from the battery, it will either make a machine-gun like clicking noise or not do anything at all if the connections are too loose or if the battery charge level is too low.

    Need help putting fuse wires back together.
    Fuse box melted last week, so I pulled it out, replaced the necessary wires, but I didn't recount which wire went where. All I have is this picture I thought to take after I took out 7 wires. http://oi59.tinypic.com/2dj9ze1.jpg

      Check the ground cable on the battery and possibly the neutral safty switch. Try to start it in neutral. Another symptom is but not always no reverse lights

      How long since tune-up? Check the throttle position sensor. You should be able to use a digital multimeter to check the tps. key on, take reading on tps signal wire, move throttle up and down, if the voltage has a glitch, I'm thinking the tps has a problem. If the voltage reading moves smoothly, that sounds ok.

      Can you check for applicable codes? Your obd 1, you should be able to check codes, yourself.

    What is causing my gas gauge to suddenly change levels on gas in the tank while I am driving.
    I just recently had the alternator replaced. I purchased the car from a local dealer 2 years ago. It only had 56,000 miles on it. And, I make payments on it as well.

      A sudden stop or acceleration can effect the float in the gas tank, which in turn can effect the voltage to and from the pcm and ipc, that will effect gage reading. Some GM makes and models have a service bulletin relating to the fuel gage sending unit in the gas tank, corrosion and or coating, that effects the gage reading. I haven't looked at the tsbs on your vehicle to see if it applies to your vehicle?
