A few times, after sitting overnight when cold, my 2006 3.0 V-6 Fusion won't start. I've tried the procedure for cold start in the owner's manual with no luck. After giving up and trying again 15 minutes later it started.
My 2006 also has the no start issue, mostly when cold, but has also had during the summer. I saw a post that said place foot on brake, turn key to on position and place vehicle in neutral. try to use your foot and roll vehicle just back a few inches, then try and start again. Weird but it worked. I have no idea what sensor this may be related to. But give it a try and see if it works for you. I have done it a number of times
My vehicle sat overnight Friday Night into Saturday Morning. Temperature was 30 at 7am. Car struggled to start the first time, had to let it sit for about 10 seconds, and then it started right up. It wasn't much of a issue last year, but now its starting to be more of an issue.
It's been 3 years this has been happening to me and neither ford dealership could figure out the problem. Finally I read this post and asked them to update the PCM ($125) and so far (1 week now) it seems to be working fine.
Have the dealer flash the computer and do a new install of the software. It is about $100.00 but will work. They will make you sign that you don't want them to diagnose it which is fine.mine starts great now.
My car will not start when temperatures are below 40. I have replaced fuel pump, spark plugs, cleaned throttle body, replaced sit intake temp sensor, added fuel injector cleaner. I do have 1 code that pops up and that's a purge valve but it shouldn't effect the start up. That and when it's warm outside there is no problem at all with starting. If I spray just a bit of starter fluid up the air intake it will fire right up. I am at a loss.
The car sits overnight temps get to the lower 30s. The next morning the car doesn't want to start, like everyone else after 30 min. to an hour it'll start. This is not good when I have to be at work, or somewhere to be.
Mine was doing the same thing and we got a new battery for it and after changing of the car started but now power to move it had to leave it sit for had an hour then hook battery back up and it started
