I am having a very similar problem on my 2000 Taurus SE. It won't start right now, but it sounds like my fuel pump is priming.
The first well-below freezing day of the year it wouldn't start in the morning. Cranked it for 45 seconds without even a sputter of ignition. I poured in a can of heet and got a ride to work. Got home, no start for 30 secs cranking. Tried again 45 mins later, same. Tried again 45 minutes later, it started! So my first thought was that I really did have a frozen fuel line and the heet took a while to melt it. Nope. 4 days later I drove to lunch, parked for 30 minutes while I ate, it wouldn't start when I came out. I called for a ride. But I tried starting it again 1 minute after the first try and it fired up immediately. Since then, it's happened 3 more times. But today is the first time after 4 hours of attempts that it still won't fire up.
But wait, there's more. I also do not think it's coincidence that my AC
, wipers, and ignition all did something similar to this over the years. Is there some component in common that I need replaced?
In 2005 it would stall when it was very hot out. At first it would start right back up. I'd say it did this about 1 every 10 hours of driving in temps over 90f. Then it got more common, and sometimes it wouldn't turn over after stalling. At first 5-10 attempts in a row it and it would turn over. (Remember, back then when I got it to turn over, it would always start. Today is a new problem where it turns over but apparently has no fuel.) It progressively got more frequent, stalling more frequently and on less hot days, and the number of tries turning the key off and on before it would turn over went up to hundreds. I kept taking it to the dealer and paying a 200 diag fee or $400 PCM
upgrade and they'd always report no problem found. I did that about 4 times and finally got a second car for summer driving and only drive the taurus in the winter now.
Then the wipers did something similar in 2006-7, but not apparently temp correlated, where low or hi would drop out. At first when low would go out I'd just switch to high which would work, and when high didn't work I'd switch to low. It got worse and worse and neither would work except once in a blue moon. I finally installed a bypass line from ground to a switch in the dash, to the wiper motor. I just flip it on high from there and have gotten really good at flipping them off when they're at the bottom of the stroke.
, same story in 2009-10. But I only drive it a little in the summer because of the problem that started in 2005. The AC
stopped working 3 times out of about 10 in 2009, and once in 2010 it worked. I'm pretty sure it won't come back on again. (compressor comes on, but warm air.)
None of these problems have ever thrown an engine code. They all start off intermittent and get progressively worse. There's got to be something in common. I'm a medical tech, so I'm good at tracking symptoms and facts about a problem, but I'm lost with modern car electrical problems other than basics like wiring up the wiper motor. It feels like the kind of problem I see at work when there's a coworker who can't put 2x2 together. It seems like a good logical auto tech could easily go "ah ha!" on this. (Assuming all the problems are related, which seems likely.)
I'm going to go try starting it again.
