Hi all,
Here's a tricky one. Just hoping for some brainstorming type ideas. I have a 1990 Legacy GX (NZ new, if that matters). The clutch was slipping and the cam belt was due for replacement, and the engine bay was pretty mucky, so I decided to pull the engine out, do the clutch and belt, and clean (pressure wash) the engine bay. None of that was a big problem, I've done a lot of clutches and cam belts with no problems, though it has been a long time since I last did that. On reassembling and re-fitting the engine, it won't start. I've checked everything I can think of, multiple times, and I've run out of ideas.
Behaviour - engine turns over OK, and occasionally pops, fires, kicks back etc. Never really gets close to running.
Things I've checked:
- Cam belt seems OK. This is the SOHC engine, not too hard to verify. The crank and cam position indicators seem OK, and the new cam belt's marks also look OK, so I don't think I got it wrong initially or that it's slipped. The belt was marked EJ18 when it arrived, but I expect that's fine (I know the EJ20 and EJ22 SOHC belts are the same).
- It has spark (checked with the plugs out of the engine)
- It has fuel (externally at least - has flow out of the return, though I can't easily check the regulated pressure)
- If I give it a bit of engine start while it's turning over, it makes no difference, suggesting either that there's something pretty fatal wrong with it, or it's too rich/flooded.
- If I put my hand over the throttle body intake while cranking it, there's very little (almost no) vacuum. I wouldn't have thought that was normal, but I've never tried that before on one of these.
- Compression sounds fairly even.
So - any ideas? I posted on alt.autos.subaru before realising that it's pretty dead there these days. Should have tried here first anyway.
Also - anyone have any ideas where the diagnostic connectors on this thing are? I thought the ECU might have some ideas for me, but I'm damned if I can find that little black single-pin connector...
