Default Cars own me, wrx is an electrical nightmare apparently

yay for 3 cars that don't run right


So a few months back the wrx decided it didn't want to start one morning, with a fairly new battery in it and nothing left on I found this very disturbing, but ignored it.


Follow up with today and now its happened 3 times this week. My wife picked me up from the gym yesterday, and shut it off for maybe a minute. Went to turn it back on and nothing. Had to have a friend jump start us.

Same thing happens today.


So, whats the problem here? Almost new battery not taking the charge? 3 year old alternator on the fritz? Completely factory wiring has a short somewhere?


I'm so frustrated, but trying to keep sane.

probably a loose connection, it sounds like it's sitting cold and losing a contact... but when it's running, the motion of the engine is enough to keep it mostly connected

... which is a sucky answer because there's like no freakin' way to diagnose it other than very very slowly

Check Everything. What are you normally doing to get it started after it does this?

If all you've done is change the battery, I can't see it being a short (unless you've done some splicing of wiring harnesses or something).

It's not unheard of for new batteries to be messed up - uncommon but not unheard of. If you still have the old battery, try putting it back in as an experiment. Might want to take the new battery to a Sears or something for a quick test.

Hope that helps a little.

I have to jump it.


Tried push starting it with my wife yesterday, but apparently we can't push it up to speed enough to turn the motor over.

I have never touched the wiring on the car, even the stereo system is stock.


I guess I will take the battery back to autozone later tonight. Unfortunately they didn't put me in the system for the warranty for some reason (they usually do, but I remember specifically on that occasion that they never asked for my info...wish I had said something) and I don't think I have the receipt. Well if its bad and they don't replace it, I will just not buy from them again (and george is going to give me back my altima redtop, bizzatch!).

If you want to check your alternator, start the car, then disconnect the battery. If the car remains running, your alternator is good, if not, you might wanna get a new one.

Yes, that was recommended to me last night, but I haven't got the chance to look at the car yet. I will test the battery, alternator, and look for any obvious loose wires tonight and get back to this thread with what I find. Hopefully its something simple and cheap (har).

Although I was just coming out of the gym, plus I am sick. Although according to brian I don't need an excuse as it was technically impossible...and that time me and my wife push started the 240 was just a figment of my imagination.


Why you guys gotta kick me when I'm down, go punch dave in the nuts or something.

Make sure the battery terminals are clean, and they are tigntened down good. It's very basic but had the exact same thing happen to a friend, her dad forgot to tighten the terminals. Sometimes the car would start other times it wouldn't.

I checked the basics yesterday when it wasn't starting. Terminals looked like they had a solid connection. Couldn't find any obvious loose connections anywhere.

You should switch the connections on the battery terminals around, that should fix something, if not prove entertaining

Well its definitely not the battery. My wife had to go to work today and the car wouldn't start, so she took a battery out of my other car. Goes to work, and now she can't come home, doh.


My boss is going to lend me one of those jump starter battery packs tomorrow, that will help in the meantime.

Is it not cranking at all?? If so check the trigger wire going to the starter, on PureEPI's car the wire came off and the car wouldn't start or even attempt to. On the RS its just a black plug with a female spade inside, the starter has a male spade sticking out for it to plug on to.

Although I'm not sure if it is exactly the same on the Wrx.

I've heard of this test before. I'd try it on my 32 year old truck, but not on my WRX. Too many expensive electronics like the ECU that could get 'zapped'. If the car runs, swing by a battery store and have them test the charging system, takes a couple minutes and is usually free.

Well it starts as soon as a new battery is jumpered to it though. So it seems like a problem with something draining the battery or with charging it. I guess if there was just a loose connection on the starter, a high enough current could overcome that loss possibly...


I didn't realize they could test it w/o taking the alternator out of the car, I will swing buy autozone and see what they say tonight.

It sounds very much like something is causing the battery to drain and not maintain a charge. If you were here we could use an amp clamp to try to narrow it down. If you can find someone with a DC amp clamp you can try to track it down. Turn the car off, measure current on either battery lead, see if abnormally high (I would say anything that registers on the meter would be too high). Of course if no current is read that would point to a bad alternator but if the alternator was bad things would start going on the fritz as you were driving when the battery completely drains. I could probably help you diagnose this if you were local but long distance it will prove very challenging. You'd be better off going the autozone route to be honest.

Good luck.

Every time that happened in one of my Fords it was the da**ed ignition switch, or a loose wire to the ignition switch.
Take the car to Autozone or Advanced Auto they'll check the charging system for free, at least that will give you somewhere to start.

Well since last night I have not had a repeat incident, so I'm tentatively calling this case closed.


I noticed when I was stuck at the gym that the battery connections were slightly loose, but I jiggled them and pushed them down and the car still wouldn't start. I assumed that wasn't the problem because of this, but I didn't think that maybe that loose connection had drained the battery to begin with.
Also everything came on fine in the car (stereo and lights), so I was thinking the connection was solid.

What I wasn't considering is the large load placed on the system when starting and its resulting current impulse. This would cause a huge voltage drop at the contacts due to ionization of the small amount of air between the terminals and the connectors. Then the car wouldn't start, but everything would seem normal inside.

Same kind of draining effect when the alternator is trying to charge the battery.

(wordy to try and make myself look less stupid for not tightening them all the way down in the first place )

So anyways I tightened them down solid, lesson learned.


(alternator tested fine)


and thanks everyone for trying to help me out, buster you win a cookie for being right.
