auto shutoff relay bad..

All a crankshaft does is transmit torque from the piston/rods to your transmission, which then tranmists torque to your axles, which then makes your wheels turn. If your crankshaft is broke, the engine will probably be locked up in a non-running state.

undo the lines at the master cylinder and place your fingers over the holes to act as one way valves . Have a friend gently pump the brakes and release any air in the cylinder. Replace the lines and start at the longest line working back to the shortest. IF that dosen't work you may have to pressure bleed the system. It is not normal to prime a new master cylinder but I make it a practice using a rod I pump the m/cyl before fitting it in the car. It saves a lot of heart ache.

you have a fuel leak in the engine compartment-don't drive unless you have to -get it to a garage it shouldn't cost much to fix-Denny

Check your catalytic converter could be clogged

you have air in your heater lines, when the thermostat opens it cools down after the coolant circulates

I assume that you are talking about car or truck (vehicle) batteries or lead-acid accumulators. If so, yes, usually temporarily, when you need to boost a dead battery with a strong one, either for start-up or for charging purposes. The procedure is simple, but can be dangerous if an error occurs. A lead-acid battery contains dilute suphuric acid which can cause severe burns if it comes in contact with the skin or clothes (though some types of fabric are resistant to its effects). If fact, it can cause blindness if it explodes into you face. So beware. If in doubt, let a qualified auto-electrician do the job instead. Would you want to venture it yourself, so I can outline the procedure?

sound like a vacuum leak.

Many times the thermostat switch can be the culprit or a separate fusebox. Does your fusebox list the cooling fan as a specific fuse? I believe there is a relay on the side of the fan for this model which is most likely the issue.

When your engine light flashes about 95 percent of the time (f not more) means that your vehicles computer (PCM) has detected a misfire and that the misfire at the time it is flashing that the misfire is bad enough to cause damage like to the catylist converter(s), oxygen sensor and a number of other things. You need to find out which cylinder has the misfire. You can go to your local auto parts store and most of them will pull diagnostic trouble codes (DTC\'s) for free. Now once you get the DTC(s) you can narrow down whcih cylinder(s) has the misfire by what DTC they pulled. For example a DTC of P0301 means a misfire in cylinder 1, P0302 would be cylinder #2 and so forth. A P0300 means multiple random misfire a much further testing needs to be done in order to diagnose. Say you have a P0301, depending on your engine size you will need to isolate cylinder # 1 to diagnose. If you have a 3.8 liter engine in most cases it\'s the fuel injector ot a bad spark plug wire for that cylinder that is bad but if you have the 4.6 liter most common cause is a bad ignition coil for that cylinder as they have a seperate coil for each cylinder but it could be an injector too instead of the coil. I\'m just giving you the most common causes but diagnosing needs to be done in order to replace the faulty part(s). Other causes of a misfire are crank or cam position sensors, a vacuum leak, Faulty spark plug wire (if you have the 3.8), engine problems (internal), electrical and/or wiring problem or even the PCM. Many other things can cause this, these are the most common. Gatting that DTC is vital in order to diagnose. If you need further help as far as testing procedures once you get any DTC\'s I\'ll be happy to helps you diagnose the problem. Hope I was able to help you understand what\'s going on...

Bad water pump, low on water..thermostat bad, cooling fan or fan relay switch broke,clogged radiator ..Catalytic converter clogged .....These are the first things to check...

How can we answer that for you !!What do you think it is?Tire,wheel bearing,shock,
