When I tried to start my car it sometimes does not want to start. The engine turns over but it doesn't crank. When I quit cranking I hear a clicking. I continues when I turn the ignition off. It will sometimes quit when I remove the key. Other times it doesn't quit until turn the ignition to Accessory and back to off and remove the key. The car will eventually crank but the Tach and Temp and Gas guages just jiggle a little for awhile and then they start working. After that everything works fine. I also notice that if I have been listening to a CD it sometimes starts where I left off other times it goes back to the radio.

I have the same problem started about 2wks ago after the car sat for the weekend and didnt drive. After trying to start it 3 times it finally started. Then about a week and a half later it did it again but in the afternoon and it had run in the morning just fine. I also noticed that the tacometer and other guages where jumping around when it first started and then it went away after the car ran for a few min.

Hello,

This sounds like the rear control unit can be going out but to be sure here is a video to show you how to run a CAN scan which can tell you for sure whats going on. You can get a CAN scanner from Amazon for about $50.00

Please run down this guide and report back.

Hi. I have a 2007 Ford Taurus and it randomly won't start. Sometimes it does, and sometimes it doesn't. The battery is only 2 months old and we just had all of the connections cleaned and checked last week because it wouldn't start. When I turn the key, it just makes a quiet click and that's it. Do you know what this might be?

It could be a bad starter among other things. The wiring circuit will have to be troubleshooted from a wiring diagram to be sure. Here is a guide and the starter wiring diagrams so you can see where it looses power and I have included how to change the starter motor out.

My car randomly wont start after I have driven it for a while. Seems to be heat related, as if its a short drive, and cool weather, it wont happen. When its a longer drive, or a short one in hot weather, it wont crank. When I turn the key, I hear a click, and that's all. This happened before, but using the clicker to turn off the PATS system worked every time, now it wont work from that at all. The car has to sit for several hours before I can start it again.

Already Checked: Battery, Starter, Spark Plugs & wires, Fuses.

Is it a relay, or something else?

You tested the starter when the engine was cranking over?Starters can be very intermittent when they fail. They can test fine and then when they get hot to a certain temp not restart the the car till they cool down.

The starter was tested and appears to be working fine. It seems like, when the issue occurs, the starter doesn't get power. It's definitely not the pats system, as when it does start up again, I don't need the clicker.

Let me say this again a starter can test good then when it gets to a certain temp it can fail and not start the car. Its not uncommon have seen this a lot and is difficult to diagnose. Because you have to check for the power trigger at the starter with the key in the start position with the starter not working at the time.I hope explained like that you now know what iam talking about?To the starter can test good a 100 different times but I still wont not rule it out with the issue your describing.I even made a feed back light for those intermittent starters I suspect and let the person drive around till it doesn't start.I have them tell me did the liggt come on when it wouldn't start?

My wife drove it to work and she said it felt like it lost power, like she has to give it more gas than normal. The engine was making a noise like a cat purring. Her steering wheel starting vibrating and she pulled over and the car died. It will start for a half a second then just turn over. Any ideas

Did the check engine light come on when this was happening? Have you checked to see if there is proper fuel pressure to the engine? Have you checked for spark to the plugs?

When it does crank it idles up then just dies, if you pat the accelerator constantly for about 30 seconds when it starts to die it will finally smooth out and start idling after this it cranks fine until it sets for about 20 or thirty minutes then you have to repeat the same procedure over again, after getting it to run smooth it still has a slight hesistation when you take off from a stop but it picks up and goes just fine. The check engine light came once but when I tried to retrieve the code my scanner kept saying error, tried another scanner said the same thing, disconnected battery and went through procedure of getting it to crank now light hasn't came back on.

My car will not stay started when it is real cold unless I press the gas a little. Then it starts fine the rest of the day.

If there is no check engine light on, I would start with checking the fuel pressure under the conditions mentioned. If the pump is a little weak, it may be causing the problem.
