Flex Fuel tune by Phatron

Question car won't start some mornings...

need some ideas here...been acting up more these days.
some mornings usually cold or not driven a day or 2, my car wont turn. I'll even let it be in "on" for a few minutes before trying to turn the key all the way to start the engine. Then when I try to start the engine, it just won't even try, and I'll have to do this several times before it will out of nowhere start to turn and engine goes on.
I thought it was my Costco interstate battery but I just checked the voltage on it while driving and it was 11 to 14 which seems fine. I started to pull some CEL's while starting it recently which were Codes P062d / P2146 that deal with Fuel Injector Driver Circuit Performance – Bank 1 and fuel injector group “A” supply voltage circuit is open.

My car is FBO with flex fuel (fuel pressure never drops below 200) tuned by Ron, Costco battery, and runs fine. Do you guys think it has to do with my led fog light bezels or led highbeam lights that don't work anymore? Its just a headache when I need to go to work and my car won't start on the first try.

Is that not the rate of charging? Battery may not be holding a charge, so maybe easiest to get it tested first.

Measure parasitic draw if you have modified factory electrical circuit. Maybe something is slowly drawing current while the car is not running.

Are you currently running a high E content? How cold has it been outside when you've gone to start the car? Ethanol and cold starts don't always mix.

FWIW mine doesn't like to start with anything higher than e50 if temps get below freezing overnight. I have actually just been running 93 past couple days with the very cold temps we have been having

The OP stated that it wouldn't even attempt to turn over, I doubt that ethanol content is the issue.

I always think ethanol is the problem. But I don't think ethanol is the problem. Or charge. But it is electrical.

no its e53-55. low temps are like 50-60, rarely anything under 50. I do live in the bay area of Cali. so its really weird that it doesn't want to turn over. Maybe i should get the battery checked out.

Do you have a muiltimeter? Without attempting to start the car, pop open the hood and check the battery voltage in the morning. Give the terminals a good wiggle and make sure they don't come off.

you mean it won't even crank at all right?
not that it just won't fire?

But then when it does crank is it normal? or super slow like the battery is almost dead?

If a battery was so bad it wouldn't even click then there's no way all of a sudden it would just crank normally, so it sounds like something is locking out your starter and won't let it actuate.
Like a neutral safety switch or something like that.

correct, when it does work all is normal but sometimes it doesn't crank. I don't think the battery is dead because all the power is on like radio and everything like that but when I turn the key to ignition, it doesn't do anything. hmm neutral safety switch... ill be seeing my mechanic and ask him this wed. thanks

yeah it's not the battery then.
And I'm not saying it's the neutral safety switch, I just mean a safety lock out type thing like that is exactly what would make the key do nothing at all, and then sometimes it works perfectly.
I know we have a truck here that sometimes won't do anything at all, and you have to take the shifter and pull it out of park and then put it back in park, and then try again. There's some sort of sensor that isn't recognizing it's in park and the key does nothing.
Then once you mess with it and get it back in the truck cranks and starts fine.

I don't think there is one.
I know there is a clutch safety switch.
A dead battery can still power radio and other things but not enough to crank the engine.
I have noticed my car would crank much slower if it's been sitting in the cold all day vs in my garage all night.

Iíve had weak or dying batteries still power things like you mentioned. I wouldnít rule out a dead battery yet. Throw a charger on it to top it off for a few minutes or bring it somewhere that can test it.

Iíve had a similar issue with my 2015 wrx. Originally it would either no crank or have trouble cranking intermittently. Found it was the battery not holding a charge. Likely because of the special load based charging built into our MY. The second time had crank but no start and same fault code as yours. Found that the positive battery terminal was loose. Our MY is really picky about its power. I would strongly recommend checking all terminals and having your battery tested as was mentioned by other users. You donít know if the battery is bad until you get it tested. And our car kills batteries.

true, but when does a bad battery do nothing at all, no struggling, no clicking, and then all of a sudden crank normally?
pretty much never

terminals could be a possibility, but dead batteries don't just spring to life

Like you mentioned before when it wonít crank it still powers the radio etc. this would imply more that either the charge cycle wasnít completed the drive before (due to our unique alt set up) you can see this all over Nasioc forums and there is a wire to remove to have it charge as expected. Or it would imply that one cell is going bad. If when it doesnít crank check the voltage. Anything below 12.5V would imply a cell is going out and may not provide enough current, but batteries recharge just a little after use (fun fact) and that may be just enough to provide the amperage to run the starter. It took over 2 months for my dying battery to finally say no more and stop cranking all together instead of intermittent. And that was after having the car for a year

ahh thanks! I will take a look at the terminals and getting battery tested.

I agree with the logic but weak batteries make cars do weird things in this age of computer controlled cars. Itís a cheap and easy thing to test to rule out the problem

update: battery checked out good. And while I was at my mechanic about to leave it did it again and car turned but wouldn't start. P2146 code came up. Tried again and engine fired up normally. Everything running smoothly just this startup issue. I'll have to check my battery connections...
