My Car Won't Start , What could it be ??

The Number One cause for your car or truck to give you the "click, click, click" no start blues is a dead battery. Just because the radio plays or the lights illuminate on the dash doesn't mean the battery has a strong enough charge to start your engine. The Engines starter requires over 50 amps to spin it, where as the radio only requires less than 5 amps.

  1. Make sure your battery connections are clean of corrosion on the inside and out.
  2. Check for corrosion inside the battery cables themselves.
  3. Check for loose connections at the battery.
  4. Fully charge a battery before testing.
  5. After charging and testing the battery or replacing the battery, Test the alternator.

What is an IAC ?

The Idle Air Control (IAC) valve controls the engine idle speed and dashpot functions. The valve is located on the side of the throttle body. This valve allows the necessary amount of air, as determined by the Powertrain Control Module (PCM) and controlled by a duty cycle signal, to bypass the throttle plate in order to maintain the proper idle speed.
Turn the ignition switch to the OFF position. Disengage the wiring harness connector from the IAC valve . Using an ohmmeter, measure the resistance between the terminals of the valve. NOTE: Due to the diode in the solenoid, place the ohmmeter positive lead on the VPWR terminal and the negative lead on the ISC terminal. If the resistance is not 7–13 ohms, replace the IAC valve.

Crank Seal Is Still Leaking How Do I fix it ??

I have a 1990 Mitsubishi Mighty Max, 3.0 V6. I have an oil leak at the front crank pulley. I have replaced the crank seal and still have a leak after the motor warms up. Do you have any ideas of the problem I am facing.
What you will need is a speedy sleeve. When the crank seal wears a groove in the crank you need to install a speedy sleeve on teh crank so the new seal has a new un-grooved surface to seal itself against. You should be able to purchase one at your local auto parts distributor.
