I'm having the "clicks, won't turn over, won't start" thing going on. I popped the hood and checked the terminals... those were good.

Here's an easy question: where can I find the starter / starter motor? (Pics would be awesome if anyone has 'em)

edit: I have a 2004 D23e

I too am having the same problem. It clicks but it won't turn over at all... Ran through the steps and don't know where the starter on our cars are located. It should be behind the flywheel under the car, but cannot find it.

Have you checked the battery? If you haven't its most likely a dead battery.

Thats what I was thinking, but when I first had this happen (a few days ago) it clicked for a while and then cranked hard and turned right over. Does that make a difference?

Also, should I be able to push-start it?

Default Re: car wont start? click here! (troubleshooting guide)

Okay you Car Guru's please help...

I have a Ford Focus Zx2 and today when I tried to start it. When I turn the key it starts just fine but then it starts stuttering and dies on me with the following lights: battery and alternator..

Well, I checked the battery to make sure there wasnt any corrosion on the battery itself (We just replaced the battery on a different occurance anyways) and if its the alternator it just wouldnt start right?

Just recently a friend and I had to change a hose that was going from the air filter because the old one had a hole in it and I checked that and it was still tight on the hose and felt no holes.

When, I give it gas when it starts it stays alive for a few more minutes before spuddering and dying on me...

Thanks

Default Re: car wont start? click here! (troubleshooting guide)

Hey guys I need some help...I installed a new optima battery about a week and a half or 2 weeks ago. 2 nights ago I went out to my car to leave a friends house and I went to start it and nothing no click nothing. Battery has juice. Tested ign. relay and replaced the blown fuse in auxilary block underhood. 30 amp maxi with a square and a key in it. What is this fuse? Does anybody know? Any help would be greatly appreciated.

Thanks,
John

Default Re: car wont start? click here! (troubleshooting guide)

So here's my story (yesterday).

2750 miles on a 1.5 month old Focus. I get into the car and it won't crank. Battery seemed ok. I manually pressed the clutch switch, no difference. I noticed instead of the mileage, the dash shows a number of dashes (-). I get out and wait a minute, just in case the anti theft has mixed up, no difference.

I call ford roadside assistance and they sent someone to tow me to the nearest dealership, which is already closed at 8pm. Not the best thought I must say It would have been nice if they had a mechanic on call to help diagnose simple problems for people willing to try, but they didn't have any.

While waiting, I checked the manual to find out what fuses are related to the PATS / ECU / starter /.... I checked the fuses, but they were all fine. Then I looked at the related relays, the first one I swapped was the ECU relay and bingo! Now I have no AC though

I called Ford roadside assistance back to dismiss the tow truck.

It's a shame people get stuck for such a simple problem. I wonder if all the Ford relays are low quality, or was I just too unlucky.

I went to a dealership today (I'm in NJ, 1900 miles away from home (TX)) and told the service advisor my story. They wanted the car to stay for today, which was impossible for me without a rental. So they scheduled it for tomorrow morning. I wonder if they are going to say you modified the relays so it's out of warrantee?! :|



Anyway, I guess in this FAQ, you should mention checking related fuses and relays


Best,
Ahmad

Default Re: car wont start? click here! (troubleshooting guide)

Your troubleshooting tips should be very helpful. I am trying to determine why my 2003 Ford Focus SVT does not crank on a regular basis. I had the battery removed and checked, but was found to be OK. I have juice to run the radio, lights, security, etc but no sound when I try to start the engine, (not even a click). It has started a couple of times since I had the battery recharged, but not a consistent basis. Most times it will not restart if the engine has been turned off and I try to start it again when the engine is warm.

Could this still be a battery or starter problem? This problem has been ongoing ever since I bought the vehicle but more so know, that the car has been not been driven for 6 months.

Also is it common for the AC not to work after the battery has been disconnected and reconnected? Does it have to relearn itself? Doesn't run cold and only on high speed - nothing on speeds 1, 2 or 3?

Any help would be appreciated.

Idle in Texas.

Default Re: car wont start? click here! (troubleshooting guide)

Lets see in anyone can help me. I'm guessing its the ign. relay, but we'll see. I have an 02' ZTS w/ 85000 on the od. In the mornings or when I go to leave from work, the car will not crank. If the car stays warm overnight, the problem seems to go away, but if it drops below freezing, the problem comes back. I have to cycle the key 1500 (or atleast thats what it feels like) times or so before it will finally turn over. When I do this, the odometer will blank out with "------" but eventually the car will start.

Sound like an ignition relay?

Thanks for any help

Ok I put in my key and try to turn the ignition but cant. I tryed turning the wheel and beating on the key and other things but it just dont want to turn at all. Not sure but for some reason a while back the LED on the dash started blinking fast and I had to jiggle the key to get it to go in then it owrked fine. It just didnt go in all the way and stopped about half way then you pull it in and out a couple of times and it went in and all was fine. I think it finally quite working. Any and all help would be greatly appreciated.

This helped immensely, the tech at my service center was stumped, I searched the forum and found this, easy fix, just needed a new coil pack.
