Default '07 WRX won't start... Just turns over.

Hello Everyone,

I've had my Subie 3yrs this past May... Haven't had any issues with it until this past weekend.. I drove from the Baltimore (MD) area to Ocean City (MD) for a Subaru Meet (MAIC)....

I left Baltimore around 9am on Saturday and arrived in Ocean City around 11:30am... I drive down coastal highway (main road) and then make a u-turn at 52nd street to head back down... She's driving fine.. No issues.. Well I turn onto one of the side streets to find a parking spot and she dies.. I press the gas pedal and nothing.. She shuts off and I drift to the side of the shoulder... Wait a second.. Try to start her again and nothing.. She tries to crank/turn over but nothing..

I usually hear the fuel pump turning on but I don't hear it coming on (when you put the key to the "ON" position).. Weird...

So I wait a bit and call a buddy who's down there and he starts to hear up.. We mess around with it... Check all hoses/cables in the engine bay... Nothing out of place/disconnected/ect..

So I'm thinking maybe the fuel pump went up... Well since there's about 100 Subaru's down Ocean City for a meet/cruise I ask around and low and behold a buddy has his stock '07 STi Fuel Pump (since he just upgraded to a Walbro) and he gives it to me..

So we swap it out and the car runs perfect.. I take it easy on her (for those who know me I'm easy on my car anyways, so easy that when I called some friends to see what they thought the problem was they thought I was bull****ting them about me having problems)

I left Ocean City on Sunday around 11:45am and get to the Baltimore Area around 2:30pm with no problems.. I drive to my girlfriends house on Sunday and drive home.. I go to work yesterday (Monday) (40 mins to work) and then drive to the gym... As I'm on my way home from the gym my car dies again.... I'm like WTF!

I try to start it again and nothing... I call my father since he's the closest to me and he comes up but nothing we can do on the side of the shoulder... My dad calls his friend who works for a Tow Truck Company and I get the Subie towed home... I get it off the Tow Truck and for ****s and giggles try to start it and it starts up but then dies within a minute or so.. WTF

I've done my research (for the most part) and thought it might be the fuel pump relay... My buddy's dad said for me to get a new relay and he would help me install it... So today I got the fuel pump relay and he puts it in and I still don't hear the fuel pump... WTF...

So we pull the carpet back in the trunk to access the fuel pump.. I take the fuel pump cover plate off (plate with 4 screws) and we see the fuel pump power connector.. He disconnects the connector and said he didn't like how it was in there (crimped i think he said) so he straightens it out and reconnects it...

He told me to see if we can hear the fuel pump now.. I turn the key to "ON" and SOB I hear it come on... He said go ahead and start it... I start it and the car fires... But dies shortly after... WTF

Things I have NOT done yet:

- Tested the voltage to the fuel pump connector
- Replaced the fuel pump with a brand new one

Vehicle:

2007 WRX Limited

Mods List -> http://forums.nasioc.com/forums/show....php?t=1519859

Thanks for reading all of this.. I tried to be as descriptive as possible.. I know this is the Newbies & FAQs sub-forum... I just don't know where to start.

-Jeff

C/N: Car runs fine for 3yrs I've owned her... Seems like she's not getting fuel.. Cranking but not firing. Fuel Pump does not come on..

I have drove 2.1 miles since the new Walbro Fuel Pump was installed and no issues. Car started fine once the new pump was installed.

I'm still scared ****less to drive far just in case something else happens and I am stranded but I am pretty sure she will be fine.

Thanks Again Everyone!

Update

Car died again after 24 miles with the new Walbro Pump. Will be going to the shop

Update

Car was fixed on 6-25-2010

Electrical issue with the fuel pump power connector.

Sorry to hear about your trouble. I have a few ideas, dunno how accurate or valuable they'll be.

Maybe take a look at your fuel filters to make sure they're not clogged? Do suby's have an aux. pump? If that died, your main pump would be trying to pump through it.

I don't think they have aux pumps...

Fuel Filter... That would make the pump not even start? I don't even hear the pump come on.. :/

And this. Actually my bet is on a loose connection on a ground as you've replaced the pump and the relay already.

Keep us updated.

I just need to find this loose connection on a ground....

I don't even know where to start...

Edit: I checked the one on the intake manifold a few nights ago.. It was tight.

Well check for the 12v at the pump, obviously when it won't turn on. If you have 12v at the pump you can then start checking grounds.

If you don't have 12v then you know it's possibly a broken wire, loose pin in that harness. Could explain why after your buddy adjusted the harness it came on.

If you don't have a multi meter, you can find them just about anywhere...Home depot, Harbor Freight (cheap), Radio Shack, Walmart (?).

He should've gotten the call from IAG, they already called me about it. It did have power at the connection going to pump in the trunk.

Hey ****er,

Get out of my thread with your useless information! I don't give a **** about a typo! Did it really make a difference? NO! Did you help me at all? NO!

Beat it!

Today I'm going to install the new Walbro and see if that fixes the problem... I hope it does but have a feeling it's something more than that....

I thought you already tried replacing the pump, and got the same results? Intermittent operation?

I was down Ocean City and a buddy had his '07 STi fuel pump in his trunk (don't know how long he had it in there though) but we installed it and it worked for a day...

it wasn't brand new... prob 30k+ miles on it... don't know how long it was sitting in the trunk...

So you put that one back in the car?
Why didn't they test the STi pump also?

I'm confused.

You took just the Walbro that you removed to IAG to have tested. The STi pump is still in the car, not working. You now have a new Walbro to install?

Hope that's all it turns out to be.

Yes that's correct... If the new Walbro doesn't work/has issues then I'm going to trailer it to IAG and have them look at it....

OK. Gotcha.

Yeah good luck. Electrical issues suck, so hopefully it was just the Walbro went bad and just bad luck with the STi pump. Maybe corrosion on the connector from sitting in your buddy's trunk.

Keep us updated though either way.
