i've noticed that whenever i start up my TSX now, it takes a few extra cranks for it to start than it used to.

i've read on here that the OEM battery is crap, and its best to switch to something better once it dies. but is it normal for it to act like this after only 3k miles? i mean, there have been times where i've hooked up a mini-vac in the cig lighter to clean the interior, or had the music playing while cleaning the inside of my car, but this is kind of ridiculous. the temp isn't really that cold either. i think we've been averaging around 40's at night.

 

Mini vac consumes a lot of power from a small battery.

 

true. i was just surprised that it's already sputtering.

 

i also use a mini-vac and have the radio on while i am cleaning my 06 tsx- no problems (knock-on-wood) with the battery. the battery is under warranty so go the dealer-maybe you can get a new one. I also have a mini cooler plugged in one of the chargers. I have owned my 6spd tsx 6 months (bought new) and it has almost 16,000 miles.

 

Do you turn the key and let the fuel pump prime before you start cranking?

There should be a warranty on the battery and you can have it replaced if it dies

 

Don't know about you guys but we here in Aust.get 2yr warranty on battery.

 

according to the 2006 tsx warranty booklet (page 36) the battery in the us gets a 3-yr warranty-100% replacement-after it is prorated.

 

I'm driving an 04 with around 31.5k miles and I'm having the same problem. It's taking a few seconds longer to start my engine. I installed a voltage stabilizer and grounding wires kit hoping to help with this, but it didn't seem to. I'll probably end up just buying a better battery once I've got some money kicking around again.

 

would that be the first position turn? i usually just turn it all the way when i start it.

i don't know. i guess if it gets worse, i'll take it into a stealership. it's just annoying.

 

it should be position 2 (on). try turning it to the last position, the position that the car runs in (after starting). leave it there for about 3-5 seconds, until the fuel pump finishes priming (you can hear it). once the fuel pump has primed then start the car. see if this helps with the number of cranks it takes to start your car.

 

did you check the distill water level? shouldn't be a issue at 3K but I had to put distill water in for my 04

 

my 06 has also felt like it has done a few extra cranks lately.

 

same problem with me.. but i think it's just a weak OEM battery.. even after a bunch of highway driving it takes like 3-4 cranks for it to start

 

same here.. ~7500mi

 

Oh forgot to mention i have only 5500 miles on it

 

My 07 with 4000 miles does the same thing. I took it to the dealer that tested the battery and charging systems . No problems were found.

 

well, here's another observation--usually my first start of the day (after leaving the car idle overnight) takes a few extra cranks.

but every start after that is relatively normal. would this mean it's more of a fuel-pump-related issue that gftgrill was talking about? or is it just the crap OEM battery? i'll have to check the distill water level this weekend.

 

my civic used to have problems with not starting if you didn't let the fuel pump prime first.

it's not a problem with a specific component. the problem is that there isn't enough fuel going into the engine to start it. when the car sits for long periods of time, most of the fuel flows back into the tank. well when you turn the key to the on position the fuel pump start pushing fuel to the motor. if you're cranking the motor while the pump is priming the line, then it's going to take a couple extra cranks to start the motor.

as long as the motor starts cranking once you turn the key, the battery is fine. It means that the battery is suppling enough power to turn the starter.
