recently ive been having problems starting the car. on a cold start i turn the key and nothing. i wait a few mintues then try again and it starts up. its been doing this for the past few days. the battery is brand new. its actaully a warranty replacement. a few times its been allittle cold out. about 65-68 degrees. thats cold for Hawaii. any idea whats up?

 

You turn the key and it doesn't crank over? If so then it's probably a starter on the way out. If it cranks over then it's got to be diagnosed to look at fuel pressure and cranking voltage.

 

Get any clicking sounds? does the radio/nav start up?

65-68 is not a cold temp for cars.

Possibly Fuel Pump needs to prime? May be a fuel system issue, depends on the sounds your getting when you try to start it

 

no sound when i turn the key. lights go very dim. and everytime after it starts i have to input the Nav and radio codes.

dont know if this is relevant but i hardly drive the car now. this actually started to happen right after i let the car sit for 3 days without starting it. this was the longest it hasnt started. also i only drive the car right down the street to my place of employment.

 

I had a similar issue last night. The TL had been sitting for 2 days. I moved it yesterday afternoon to wash it in the drive way. When I went to leave later that night, I had full lights and instruments but it would just sit there cranking. I let it sit for 10 seconds and it finally turned over and it didn't do the usual "cold" idle.

 

When that happens have someone hit your starter while holding it in the crank position.

Check your battery terminals it could be possible they are loose or broken.

Once the car is running check the charing voltage off the battery. It should be 13.8-14.2

Like I said diagnosing over the internet is only as good getting gum for 75 cents.

 

sounds like your battery is dead... you should get it checked or try jumping your car

 

Agreed with Nokiaboy, your battery died after letting it sit. Get a jump, and drive around for 20-30 mins. and it should recharge the battery. In addition, what I would do is look for corrosion around the battery terminals, if there is; clean it up, and place the terminals back on the battery.

 

i agree. i just wanted to know if anyone else had a simalar problem.

something has to be draining the battery then right? i mean it just got replaced about month ago.

thanks all for the input. i just went outside to start the car and it started normally. ill try again tomorrow morning.
