Long Crank to Start When Warm

Ever happened you any of you? Happened to me for the first time tonight. Had driven 15 miles home from work, stopped at the gas station 5 minutes to fill up. Turned the key to start and.....crank.....crank.....about 4-5 seconds. Haven't heard that since the carburator days. She normally always fires within 1-2 seconds.

Very weird. I'm think it has something to do with the crank sensor. Anybody experience something similar?

I had that going on until I got the Sunroof TSB fixed and the dealer charged me up.

Apparently the sunroof still draws current when the car is off. I didn't affect me until the this year when it got cold.

I don't think that's it - battery has plenty of juice, according to EVIC. I'm thinking some kind of vapor lock, or the position of the throttle sensor when I stopped the car.

I've used this car to run numerous errands, and had many "hot starts" after it's been sitting only a few minutes, which is why it surprised me.

Hemi31 over on ****** suggested I may have filled the tank too much (I always squeeze in a bit more after the click), and this may have caused it.

I never heard of this before.

Resurrecting this, as I had an interesting issue today. Started the car this morning to go to work, it has been sitting for 6 days, and temp was 18*. She fired right up. Got to work, and it sat 1.5 hours, went out to run an errand, and she cranked at least 5 seconds. Almost thought she wasn't going to start. Drove about 2 miles, had to stop and drop off some mail, car was shutoff maybe 1-2 minutes, and then she fired right up again.

Get to my next destination, where it sat about 1 hour. Temp is now only about 23*. Came out to start her, and again, cranked 3-4 seconds this time. What is going on? She starts instantly after a week of sitting, but on after sitting 1-2 hours, she is taking a while to light - engine turns over just fine, and battery in EVIC is averaging 14.1 volts, as it always has since new. I've had it 3 years in February, 10,000 miles on her. Car is now going to sit about 6 hours, so I guess I'll see what happens when I go to start her up this afternoon.

Just something with the cold?

Have you ever done an oil analysis? You may have leaking or seeping injectors. When they seep or leak, and then you try to start it up you get a slight flooded condition causing more cranking etc.

I have seen several LX cars with this issue. A simple fuel rail leak down proceedure will also show the problem it that is the cause.

Just a thought.

I thought of a fuel rail leakdown myself. Car only has 10,000 miles, and never an issues. Why would the car start instantly after sitting for a week though, if this were the case?

That would be because the gasoline had time to vaporize and then go out of the chamber....open valves, pcv etc. It is when it is warm and spritzing while sitting there under pressure and still wet that it produces the flooded condition.

Interesting. I'm sure if I took it to my dealer, they would be "unable to duplicate", or just tell me that those crank times were within the realm of normalcy.
