ALWAYS start with the simplest thing first, otherwise you will get "taken" at the Parts Stores.

Clean your battery terminals! This is the MAIN cause of not starting. Clean the clamps. Use the tool they sell, or sandpaper.Inspect the ciring for corrosion. Then make sure to re-connect the clamps tighly enough so there is a good connection. (you will not be able to move the cables).

If the vehicle doesn't start, have the battery tested. Make sure you have the correct battery for your vehicle. Different batteries have different sized terminals and different cranking power.

First, try to get a jump to get the car running. If getting a jump won't start the car there is something else wrong. If the car starts, it could be that your battery is too weak to start the car but has enough power to run the lights, etc. It takes a lot of battery power to turn the starter over.

I wouldn't doubt it is one of these two problems.

Where is the oil sending unit on a 1996 mercury cougar xr7 ? Its cause my oil pressure gauge is bouncing up and down...i dont know why...can anybody please help me thank you so much

The low oil pressure warning lamp will illuminate anytime the ignition switch is turned to the ON position without the engine running. When the engine is running, the light also illuminates if the engine oil pressure drops below a safe oil pressure level. To test the system, perform the following:
If the oil pressure light does not work, perform the following:
  1. Turn the ignition switch to the ON position.
  2. If the lamp does not light, check for a broken or disconnected wire around the engine and oil pressure sending unit switch.
  3. If the wire at the connector checks out OK, pull the connector loose from the switch and, with a jumper wire, ground the connector to the engine.
  4. With the ignition switch turned to the ON position, check the warning lamp. If the lamp lights, make sure the oil pressure switch is properly grounded in the cylinder block, and if so replace the oil pressure switch. If the lamp still fails to light, check for a burned out lamp or disconnected socket in the instrument cluster.
To diagnose an oil pressure light that stays on, perform the following:
  1. Check the engine oil level and top off as necessary. If the engine was 2 or more quarts low on oil, test start the engine after topping off the oil level and recheck the oil pressure light operation. If the light stays on, stop the engine immediately and go to the next step.
  2. Disconnect the wire at the sending unit, then turn the ignition switch to theON position. If the light remains on, check the wire from the sending unit to the gauge for being shorted to ground and repair as necessary. If the light goes out, turn the ignition switch OFF and go to the next step.
  3. Replace the oil pressure sending switch with a known good switch.
  4. Start the engine and check the oil pressure light operation. If the light stays on with the engine running, stop the engine immediately to avoid severe engine damage until the cause of the problem can be determined.

WARNING
If the oil pressure light remains on while the engine is started, stop the engine immediately. Do not operate the engine until the cause of the problem can be determined. Operating an engine with low oil pressure will cause severe internal damage.

Possible causes for an oil pressure light to stay on are:


Pinched or grounded sensor wireDefective oil pressure sending unitRestricted or severely leaking oil filterExcessive internal engine bearing clearance.Insufficient or severely contaminated engine oilBlocked oil pump pickup screen or severely worn oil pump

My 2005 Toyota 4runner with a v6 will not start when the temp gets below 32 outside what could be my problem


There could be several reasons why your engine will not start. When you first turn the key to the On position (without starting the engine), the lights on your dash should illuminate. The yellow Check Engine light should come on, at least for a few seconds. If not, then you are not getting power to your engine computer. Perhaps the fuse is loose. Locate the Engine fuse in the cabin fuse panel and wiggle it while watching the dash lights. When the Check Engine light illuminates, you should be able to start the engine. If not, then it is time to check for spark. You can remove a spark plug, install a jumper between the ground electrode and the engine block, insert the spark plug securely into the spark plug boot, and have an assistant crank the engine. If you see your spark plug firing, then you can assume you have a fuel delivery problem. Have the system pressure tested. You may have a weak fuel pump.

When I turn my key to the on position the check engine light will not illuminate and the car will not start. If the check engine light illuminates the car will crank fine. What is going on?


Could be a problem with the key switch or the wiring. Someone would need to find out if the computer is getting power when the key switch is on.

1998 bonneville engine hesitation


Is there an illuminated check engine light on the dash? That sounds like a failing TPS (throttle position sensor). Unless you have low fuel pressure! When (if ever) have you replaced the fuel pump and/or fuel filter? Are you running the correct type of fuel in the engine? If you have slow or sticky fuel injectors, a can of Seafoam might help!

94 wrangler 4.0 fuel pump wont turn on


If your check engine light does not illuminate when you turn the ignition on then your jeep ecu is in need of repair. The check engine light has to be on for the fuel pump to get power. Try leaving the ignition key in the on position for a few minutes to see if the check engine light does eventually come on and if the fuel pump starts to work then.
