So I encountered a weird issue with a 93 Leg the other day. First encounter. Won't start, voltage kinda low, but engine cranks fine. (brand new battery and alt) HAs the "hollow" cranking sound of a timing belt off a few teeth. Reset belt, it was 1 tooth off, probably installed wrong, not slipped......not the problem. Hmmm......I check electrical a bit. Turn key on. CEL lights for 1/2 sec. then goes out. Will not go into test or read mode. Swap Ig. relay, no change, Clean connection of Fusible link supplying voltage to the IG. relay, no change. Battery starts getting really low, so we hook up cables. Let it charge for a while. Try again, now CEL lights, almost steady....or at least more so. But still is blinking on/off randomnly (not in test mode, not code flashes, I know what those are). Try to start......struggles, but eventually catches, and starts. Now before it started, the cranking sound went back to a normal cachuga-chuga and fired. Shut it down and try to start again.....now cranks hollow won't start, no CEL again. I think ECU cuts out fuel and spark signal. Try a few more times......Back to sounding good, CEL lights (but still is sketching out), Fires up good. Has fired up each time since. My question is, has anyone seen an ECU fail like this. I've seen them fail to light the CEL at all, but never seen it trip out like this. Going to try a new ECU in the car and see what we get today. I'll take video of the CEL. Just thought I'd ask the community. Thanks.- 26 replies

1997 Subaru Legacy Outback 2.5 A year ago I bought my 1997 Subaru Legacy Outback 2.5. It was in great condition and ran like a dream. The CEL was permanently on, the previous owner said it was a bypass (something to do with the exhaust?) and not to worry . Never had any issues with it until now. A couple of months ago it started occasionally not starting the first time I would turn the key….I would take the key out, reinsert it and it would start right up. I did notice that my key was kind of loose in the ignition and I would have to wiggle it to get the ding ding noise. I also noticed a lot of corrosion on the battery terminals. Three weeks ago I ran it (for the first time) so slow on gas that the fuel light came on., I put gas in and I noticed the fuel light came on a couple of miles down the road, but just for about a mile. It also lagged once going up a hill. The next morning it would not start at all….not push start and not by a jump. The battery drained down to nothing and stayed that way. Replaced the fuel filter. It then started with a jump, but the idle was rough and it wouldn’t stay running. Also blew out white-ish smoke for a bit. Had a gear head friend take a look….fuel to engine problem was suggested.He also noted that my O2 sensor wasn’t there (probably the bypass previous owner did and reason the CEL always on) He brought his code reader..but it wouldn’t run long enough to read anything. I replaced the fuel filter…..and the spark plugs….and got a new battery. Fuses have all been checked. It’s not the MAF either. Now it starts (still has the ignition issue), but it is misfiring and the check engine light is flashing. Any input would be much appreciated at this point. I live 15 miles out of town in a very rural area. So it has been devastating to my daily life (getting food, propane, auto parts store, and not being able to get to work for 3 weeks).
