No start, dash lights on - SOLVED!

Hi guys, apologies if it's custom here to do an introduction thread before posting.

My partner and I have a 2001 Forester SF GT Automatic here in Aus. The car started to have an intermittent starting issue. I've searched for days trying to find people with the same issue on this site and all over the internet to no avail. The car doesn't want to start at all now. When it's playing up, the symptoms are; when the key is turned on and even when key is removed, the low fuel light is constantly on and so are a bunch of warning lights on the top right, NOT in the same way that the lights come on during normal ignition start procedure. Eg; the engine warning light is faded but on. I go to crank and i get nothing, not a thing. When the problem first happens (just ignition on, not trying to crank) I get noises from relays clicking for about maybe 10 seconds, then all clicking stops and the problem persists. Sometimes and only randomly, the problem goes away and the car starts and acts fine. I replaced the ignition switch this afternoon thinking this had to be the problem. Still the same, no start, dash lights stay on even when key is removed.

Funny thing is, if I slip the gear stick into reverse (only reverse) with key off (key on lights still stay on), all the dash lights turn off. As soon as I put it back into park, and key back on, boom, same problem.

I'm trying to diagnose this as best I can. I've got another forester to pull parts from but not close by, so really want to get the right bits one time only if I can.

One forum thread I read the guy had exactly the same problem, ended up being and earth problem. He'd done his head gaskets recently, we've had no major work done on this car since we bought it 2 years ago and it's been fine till now. I'm happy to test earths if you have a process I can follow with the multimeter. All the connections I could find were fine with 1 exception. I found a broken earth wire under the intercooler that I can not for the life of me find where it was hooked up to. I scratched it to connect to the chassis to test for any change and nothing. It seems it's definitely not the issue either way.

That's all I can come up with for now, I really hope someone knows where I can go from here to diagnose and at least this problem is now on the internet so people with the same issue can actually find a fix for the same issue!

Where abouts is that broken earth wire? Under the intercooler, kind of on top of the turbo/at the back of the (aus) drivers side fuel rail? I noticed I had to be super careful with that earth when replacing my turbo. It's meant to connect to the chassis, on one if the bolts that holds the boost controller on place on the strut tower.

Could be different on the 2.0 litre (mine is an 06 xt) but worth a shot. Throw up a pic of where it is.

Having said that, could 1 broken ground there stop the car starting? I guess it's possible if that supplies grounding to the injectors, if that's even how they work lol.

Hi Kevin, thanks for the welcome and moving the thread.

The battery is a Century less than a year old in A1 condition. I can't do a manual code read on this model cause it doesn't have the black plugs, only the two green ones. Currently can't get the car to start to take it to someone and get codes read. In the morning I'll head down to the other car and I'm going to grab the alarm module (the separate central module as well though it shouldn't be that) and the neutral switch from the auto.

I don't know of any mobile mechanics around here with the proper code reader. I'm really stumped so far but I know the alarm could be the culprit cause it has control over the car cranking as far as I'm aware. So basically if these things don't work, then I should be checking for an Earth problem.

Re; MosquitoCoils. I don't think that wire is the problem, I grounded it to the chassis and to the engine (which is where it comes from anyway and there was no change, also it doesn't move around and touch on anything to obviously suggest that it's causing an intermittent fault but I'll pull the cooler off tomorrow and have a look. It connects to the top engine side of the bell housing right under the top mount.

ok so calling it a night finally, this is the wire in question

http://www.subaruforester.org/vbulletin/f85/where-does-ground-wire-go-121037/

So basically, this evening I removed the negative cable to the battery briefly to do some testing, maybe for 5 max 10 mins. I then went ahead with re-connecting this wire. low and behold the car started straight after. I have noticed though, (not every time) when I disconnect the battery for a long period the car sometimes goes back to normal. I will keep this thread updated on what happens as this problem has been happening fairly often, every day or two it comes back to say hello. At least I can now head into town tomorrow and get a code reader run over it. So MosquitoCoils you may just have been right in suspecting that wire, time will tell! Any further advice is still very welcome,

Cheers

It's possible that disconnecting the battery has reset the ECU, clearing any codes, and so the car starts up.

If you're not aware of the process:

How To: Reset ECU (Engine Control Unit)
1. Disconnect battery - I disconnect both terminals; earth = first off / last on.
2. Disperse current; depress brake pedal / switch ignition on as if cranking - wait 15-30 mins or let it sit overnight.
3. Reconnect battery
4. Switch ignition on - wait 3 secs for the idle air control solenoid valve to initialize.
5. Start car - touch nothing other than the key! (optionally - get a coffee while you wait)
6. Idle to normal operating temperature (radiator fans will come on) then switch off.
7. Switch on again and you're good to go.
