So I have a 2008 ES 350 with 53,000 miles on it. In December of 2015, It was starting fine, then it sat for about two weeks without me driving it. When I went to start it, it had to be jumped. It took longer and longer to start (more cranks) until I took it in. Also there was a delay between hitting the lock button on the handle and the car actually locking. The battery was still the original one, and the dealer tested it and it was in fact in need of replacement. Now here's where things get weird: I replaced the battery with a brand new Interstate 24f 700 CCA battery from Costco. The car starts now, but it is kind of slow (about 4-5 cranks) to start. Does anyone know what is causing this?
Thanks!

N.B.: also, the car starts faster (two or one crank(s)) if I first put it into accessory mode then start it

 

Also, if it helps anyone, here is a link to the battery from costco: http://www.interstatebatteries.com/p...841-2147384906

 

Huh, I had similar problem couple of days after I replaced the fuel filter. The problem was the o ring on the non-return valve.

 

@LjeksesES Is that the same thing as the idle air control valve? Thanks!

 

No. That's an o-ring that is located in the fuel tank. The o-ring was not put in the right way and there was a fuel leak, the fuel returned into the tank and there wasn't any pressure in the lines so the engine took longer to start.

As FYI, the reason for that is by putting the car into ACCESSORY mode first, you are pressurizing the Fuel system first before cranking the engine.
This is actually a good idea as well in cold weather as it helps start the car.

As already mentioned, the issue you are having is not battery related.
Definitely FUEL related though as in FUEL PUMP, FUEL FILTER, etc etc

 

The Interstate 24F battery I bought from Costco is white with green trim. Black looks better.
