2004 Outback 3.0 H6 refusing to start
Posted 12 August 2013 - 03:43 PM
- it had a immobilizer, connected to the starter! If not started after 30 seconds after unlocking the car, the immobilizer would kick in! And the starter would not work! And a lock/unlock would be necessary!
From one day to another, the alarm stopped working, and would not release the immobilizer! After 30 - 40 tries, I pulled off the +cable from the battery and replaced it!
Now the alarm worked fine! Immobilizer releasing the starter! But when I try to start the car nothing happens! The ignition and fan turns on and the starter tries to turn the engine over but it won't ignite or anything.
WTF is wrong
My subaru dealer is saying the ECU is dmaged and needs to be replaced!
I don't know why, but i dont agree! I can't figure out how this could have happened!
Please help me

If you just pulled the (+) cable, waited, and then put it back on, that itself would not damage the ECU.
No sparks, no drama, no crossed cables?
If the immobilizer decided to do something bad, who knows.
Can you disconnect the immobilizer?

I just noticed you're in Sweden. Is it a second generation or third generation Outback? Different markets got different models in 2004 which is why I ask.
Just for grins, disconnect the black ( - ) cable from the battery for 30 second. Reconnect with the key off. Get in, turn key to "ON" but don't start it. Let the gauges sweep and leave it there for 10 seconds. Probably will hear some relays under the right side of the dash click during this. Then try and start it up!

Er hc! If that helps!
I think the engine spins, at least I hear the starter going round and round, but nothing happens! I will try the black cable today

but, as mentioned above, your model 04 may not be prone to that failure.

So the starter interlock / alarm starter kill curcit has a box marked keyless entry unit or somthing like that inside it is a set of switchs 3 or 4 of them in differnt positions actavates differnt things eg ig kill starter kill light on or off horn ect there is realy good info out there on how to set it up. Also i think if you try 3 times to start unsucsesfully will not let it start at all. On the six we used on race buggy there was one wire had to be hooked up to fool the alarm engine kill curcit or whould not run. also like tex said check feul preshure and confirm ig realy power up.

1.unplug battery = car won't start.. Starter turns the engine
2. Remove alarm along with the immobilizer(note that the immobilized only prevented the starter to turn) but now with the alarm gone! The starter turns! But engine won't start
Ivan imports!! Where can I find this box you are talking about?

If you haven't checked the fuses under the hood and in the dash yet I suggest you verify they are good using a test light probe. Fuses should also be checked first if there is a suspected electrical problem.

possible cam position sensor. Or crank postition sensor but I THINK injectors are cut off if the cam sensor is bad.
any DTC//'check engine light' codes?

It seems odd this problem happened after the alarm system was worked on. That makes me tend to think that something else beside the ECU is causing the trouble but it could be the cause of the trouble. If just the injectors aren't working you should be able to spray some starter fluid into the air intake and start the engine.
If you do end up needing a ECU you should be able to find one at a salvage yard for a lot less money or get a rebuilt one for much less than new.

a dealership may be able to at least confirm if the ECU is damaged, or just needs reprogramming.
also, I THINK there may be a couple availble thru this German site - do a search using the number 22611AJ220

If it backfired that could mean the timing chain has slipped position. You better check the compression. I doubt replacing the ECU is going to fix the trouble.

the control keyless entry mod might bo on older cars have you naroowed down the imoblizer wire on ecu ? and have you treid a noid light on injectors i have a cut down wire harness for 3.0 h6 could check specific wires if needed but dose sound like you may have damaged ecu I had one i ruined lost spark and feul but could see the burnt trace inside ecu have repiared some ecus but is very difacult because is so small inside

I'm not sure how you measured the valve timing which I am refering to, not the ignition timing. The error code P0406 refers to a problem with the EGR valve circuit. The Hc error refers to a problem with the communications bus line circuit and that needs to be corrected. Here is a link for some info about it.

All keys to the car is reprogrammed whit codes from Subaru factory! This was my first thought, that the car forgot who it was!
groundings for ecu are measured, the removed one was a Gemini alarm system with connections only from ignition to starter! Everything is removed from the car!
Ivan imports!! No if there is a immobilized built in the car and I can unlock wire past or cut this I would like to know
Posted 17 August 2013 - 03:16 PM
If you are sure there is no external control for the injector circuit and have made sure all power connections to the ECU are okay then replacing the ECU may be the next best thing to do. I would first verify the engine runs using starter fluid.
