so very rarely over the last few months, our TL (with ESS) has had an occasional tough time starting, where the engine would crank for 5-10 seconds before finally catching. Yesterday, for the first time, it actually failed to start, after cranking for 15 seconds or so before giving up on its own. I tried it once more, and it fired right up!! Weird, right??

I haven't explicitly tracked this, but I think it happens on a warm engine only. The instance yesterday happened after a two hour drive, then shut it down for 10-15 minutes, and then it failed on the restart. Made a couple more quick stops after that with no issues restarting then, or today.

My brain is telling me battery is the logical and likely culprit, but my gut instinct thinks the battery is OK ... maybe fuel? Back in my saab forum days, this was always a CPS replacement.

Just broke 20k mi, so I still have plenty of warranty, but I know the dealer can't seriously troubleshoot such an intermittent issue...

anyone have any advice? anyone else have similar symptoms?

If it is cranking at normal speed, it certainly does not seem to be the "low battery" issue we are seeing elsewhere.

Should we assume it is not trying to "catch" -- just cranking away with no "partial" starts.

Either the fuel injectors are not injecting, or the spark plugs are not firing as a first guess. Can a fuel injected car "flood?" I guess there are more exotic possibilities with these computer heavy vehicles.

As you say, intermittent problems are extremely difficult, but I would get to a parts store next time and get a free OBD download anyway as soon as possible.

Good luck. It will be interesting to see if others have had the same the problem.

The 2010 Ford Fusions had a problem of extended crank times before the engine fired up. It was due to one of the main grounding points in the engine compartment . It seems that the grounding area was painted over before the cabling was attached and the paint was preventing a good ground, the fix was to scrape away the paint and re attach.

Update:
Took it into the dealer two weeks ago to have them check it out while they were working on the park release and cruise control recalls. Of course they couldn't replicate it, but they said the battery checked out low. They recharged it and said the battery tested OK after that.

The very next weekend, it happened to me twice, after filling gas, and then dropping off some boxes at a friend's house (separate days). Both times after the car was fully warmed up, turned off for 5-10 minutes, and then tried to restart. Both times, the engine cranked and failed to start, but then fired up like normal on the 2nd attempt. I guess I'll be calling up the dealer again to document this... Yet there are plenty of times in seemingly the same situation, like filling gas, where the car starts up just fine afterwards. But these few odd intermittent cases...

I hope you guys don't have this issue, but I kinda hope some of you do, so that we can figure out a solution that much faster!!

So what was the dealership's answer for the the battery being 'low' ? Sounds like more diagnosis and or battery replacement needs to be done. Thanks for the update. Good luck.

I've experienced this too, but after several years of this and NO help from Chrysler, the pattern I've noticed is that more often than not it happens when the wheels are turned. Strange, yes. It's less likely to happen if the steering wheel is straight, but if the wheel is turned sharply and you start the car from that position, for us I've noticed it brings it on. Not sure if a left or right sharp turn of the wheel brings it on.

Hi chris.,
We're truly sorry that you are having this concern. Unfortunately, as you know, the dealers are unable to asses this concern if it cannot be replicated. With that said, if you are able to replicate this for you dealer, please feel free to send us a private message so we can assist you while your van is at the dealer.

Sounds like the classic cam sensor problem. When one fails it takes a few revolutions of the engine for the ECM to determine engine timing. Once timing is calculated, it starts the engine. Should throw a code though or at least have one pending. Sometimes the ECM will place a code as pending to see if the problem duplicates before lighting the check engine. It varies how long they stay pending but most will stay at least a couple of key cycles.

This just happened today. Drove the vehicle to my office, came out three hours later and pushed the start button, and it cranked for 6 or 7 seconds before it fired up. The crank was very fast, so I do not suspect a battery issue. No CEL.

Get a free OBD download & printout ASAP at a parts store or other place. It may have thrown a code that does not trigger the dashboard error light. Waiting may let it age out of the system before the dealer sees the van.

If it is the fuel pump, there would be no codes.... Just difficulty starting on an intermittent basis, until it gradually becomes worse over time, and finally you feel some hesitation when accelerating hard (under load), and ultimately when it refuses to start most of the time....

Of course, there are many other electrical, electronic and fuel system issues that can cause starting problems, but I have seen/lived what you are describing ... and sometimes it is just the most obvious and basic problem (like a fuel pump), rather than a complex, hard to diagnose problem.

A dealership technician might determine the root cause quickly and easily, or might start pinpoint testing of all engine starting related electrical and electronics systems.

Good luck..
