Car wont fire.....

Car stalled out on me one nite and had to have it towed. 2004 wrx 2.0 invidia downpipe stage 2 tune and turbo back exhaust and cobb sf intake. Changed fuel pump to a walboro 255 thinking it was fuel related car ran fine then stalled out the next morning at idle. Changed fuel filter in engine bay and ran fine then did same thing next morning. Drained all fuel changed filter under the hood again ran new 93 and now it wont fire

Pull your plugs. Are you getting fuel? Clogged injectors?
Fuel. Are you getting a spark. Coilpacks? Bad fuse?

Definitely getting a steady stream of fuel and as for plugs and injectors i havent checked those yet. Would there be any CEL associated with bad plugs? Maybe crank or cam sensor possibly? But that would throw a CEL code if im not mistaken. At this point im very frustrated and would rather not take it to a garage to get bent over with diagnosing costs and labor....

How old is the battery?

**Anub1s** · 02-19-2013 02:54 AM

How well seated is the ground on your battery?

**Clark1989** · 02-19-2013 05:33 AM

Well ground wire looks fine and my battery is a subaru battery and its only around 4 months old. Even had it hooked to my truck when i tried to start it

If it turns over strong with the starter it's most likely NOT the battery or its connections. Anything else is still possible... Pull the plugs, are they wet? If you get no spark they should be soaked in gasoline. If they're dry your injectors are likely not firing (not opening...), check your fuses also.

What about the fuel filter in the pump assembly in the tank? That has been known to get clogged over time...

Ok update on car. Let it sit in a heated garage and it fired up. Why would it fire when warm but stall and just crank when cold?

**Mikie13** · 02-20-2013 04:45 PM

Battery.

**Clark1989** · 02-20-2013 06:24 PM

Well car still wouldnt fire the other night even with it hooked up with jumpers to my truck

**Anub1s** · 02-20-2013 06:42 PM

So car turns over in cold or warm, won't start when cold. But will turn over and eventually run when it's warmed up? Could be fuel related, still.

That is definitely typical bad battery behavior, although it usually rears it's head in the form of slow cranking; not cranking and lack of starting.
