Question about 1994 Ford Taurus

1 Answer

1994 taurus doesn't start like it used to ....I have to keep turning the ignition over and over; it eventually starts but during this process of attempting to get the engine to catch, the fuel gauge is reading full when I know it only has 1/4 tank. The gauge eventually goes to 1/4 tank after engine starts; after this initial attempt the engine starts ok. The trouble starting only happens when car has been sitting overnight or for 1-2 days.

    During the past winter, for a week or two, it would start but cough out before I could put it in gear..(it only happened briefly and only about 3-4 times total.) I put heet in the gas tank for a couple of weeks after I filled up tank. That cleared up and everything was ok until about a week ago; I only have a hard time getting it to catch when I am attempting to start it and only after it has been sitting either overnight andor for a day or so. After it starts, there is no problem, it keeps running fine, and if I am going to the store and turn the car off it starts fine when I get back
    and start it. I have noticed that while I am attempting to start it the gas gauge reads full initially, then goes back to where it should be. The oil and transmission and all fluids are checked routinely and the oil and filter and air filter were changed about 2 months ago. I am not working now, so I don't drive my car as much as I used to. The battery cables are ok; mileage is about 151,000.

    Not sure the gauge is any indicator of the starting problem itself. When was the last time there was any tune-up work performed? Plugs, cables, cap, rotor button, injectors cleaned and fuel pressure checked? Did this suddenly start happening or has it gradually gotten harder to start the vehicle. Let me know some details and we will go from there to help you out.

Based on the information that you have provided me, my attention is now centered on the ECT Sensor (Engine Coolant Temperature). This sensor provides information to the ECM to richen the fuel mixture on start up and also to lean out the mixture as the engine warms up. Very similar to the old fashioned choke in operation. A cold engine requires additional fuel to start, while a warm one does not. This matches your situation of a cold start versus a re-start and also explains why you are having to cycle the start sequence several times to fire the engine. Those cycles are finally providing enough fuel for start up.

Check with a local auto parts outlet to see about having the ECM read for a memory code related to the ECT. Most of the stores will now do this testing for free.

Let me know if this helps you out or not. Thanks.

How can I hot wire my ford Taurus? I lost my key


Problem with hot wiring the ignition is that the vehicle will start and run but with out turning the ignition the steering wheel will be locked > I suggest a new ignition switch , you can always hammer a flat head screw driver in the ignition were the key goes and turn the ignition. Either way you will need a new ignition switch .

Do you smell gasoline fuel ?? When there's too much fuel, it saturates the spark plugs, preventing ignition. Let it sit for an hour to let spark plugs dry, then it starts OK later. Next time, turn starter without giving any throttle or very small throttle as engine turns. Myself, when my 2006 Dodge Plymouth minivan (sitting in storage) needs to start, I squirt (half second) starting fluid into air filter, close the air filter housing to trap flammable gas from starting fluid, then turn the engine without pressing on throttle. When the engine starts is when I give it a little throttle to bring up the RPM to 2,000 until it idles on its own without stalling from cold engine.

I have a 2000 Ford Taurus. My wife left the radio running with the ignition off for a short while. Now the car won't turn over, won't start, won't jump. There is one click when trying to s


The click you are hearing is most likely the start slenoid making contact, however you should short the large wires @ the solenoid to make certain the starter still doesn't run, if so try tapping the starter with a hammer to shift the comutator a litle and try to start. Even if it now starts the starter will continue to give you problems so the proper fix is change the starter

When I start my 96 ford Taurus I have no radio or windshield wipers or speedometer. But when turn key backwards radio and wipers work


I am betting it is your ignition switch- it is just like any other type of switch, in that it has contacts that eventually wear out. Once you turn the key to start the car, it returns to a position that maintains the contacts to power your accessories, and it sounds like those contacts inside the ignition switch are worn or broken. The "acc" contacts when you turn the key backward are rarely used so they are still in good shape, unlike the "run" contacts which get hit every time you start the car.

My 94 Taurus will not turn over. Lights work...I replaced starter then ignition switch. Car will not turn over. It has a history of intermittent starting problems. It may or may not start. Now it...


They have a bad ignition problem. Its more than likely the ignition. Turn the key on, Then right below the ignition theres a hole. take a long skinny phillips screw driver and push it up through the hole and you will hit a release for the ignition. Push it up as you pull the ignition out. Then try to start the car with a flat head screwdriver. Write back if that doesn't work but i have a feeling it will.

My car want start it turns over but want start


You could try resetting the computer. The car maybe in lockout mode. Try turning your car over….leave the ignition on. Wait exactly 10 min. Then try turning over again….again leave the key on. Wait exactly 10 min and do it a third time….this time the car should start…maybe run a lil rough while it relearns the processes of your vehicle again. It is important to wait the exact 10 min each time. You will probably need a battery charger or a set of jumper cables because if your car goes low during this process it will not work. Good luck and I hope this works.

94 taurus wont start after 30 minutes of running until engine cools off


the taurus uses a "thin film" ignition module located on the side of the distributor where it touches the distributor there is a film of heat transfer paste to keep the module cool this paste dries out and, the module heats up and, you have a "no start" until the module cools
the paste is availlible from Ford or, radio shack

Starts but doesnt stay running


I'm not sure your car even has one but the symptom is reeeaal familiar; 'starts fine, dies afterward.'
Ignition coils used a special resistor or a relay that switched one in or out of circuit depending on whether you were starting the engine or afterward, running it. The special resistor started at a low value of resistance but rose rapidly to a higher one allowing more current to flow through the coil primary to start. The design using a relay simply bypassed a fixed resistor (not heat sensitive) during the cranking of the engine.
The resistor allowed either a full 12 volts or at least a good bit of it to be used for starting by supplying the primary of the coil with a much higher voltage than needed to only keep it running. This allowed the use of a 'hotter' coil that stepped up the voltage more than was done 50 years go. That high current could not be tolerated for longer periods as it would eventually cause heating to the point of coil failure.
If you can come up with an electrical diagram of your ignition system, check the path of voltage to the ignition coil and keep an eye open for a symbol of a zig-zag line inside of a rectangle, a symbol often used in other schematics, and if you have one that has an arrow across the zig-zags, this is the thermally sensitive resistor that needs no relay to function.
These were often mounted on the fire wall, not far from the steering column so the wire run wasn't overly long and are often in a ceramic rectangle with wires attached to either end.
