I have had a CEL on my '93 legacy for about 3 months now for a purge control solenoid. Yesterday morning my car cranked really good but just wouldn't start. I pulled the codes and got 21 CTS, 32 oxygen, and 35 purge control. I put in a new CTS last night and it was a little hard to start but ran well after it started. This morning I went to leave for work, and it wouldn't start again! Same thing it was cranking hard but just wouldn't start... could the purge control be causing this? I thought that was just emissions junk.... thx!

Did you use a OEM sensor? You did replace the ECU temp sensor right the one with a two pin connector. Try resetting the ECU unplug the negative terminal on your battery for a good hour and try again see what codes come back. A purge solenoid could cause some running issues so I could definitely see startup being a possible issue.

Problem solved... just wanted to follow up the thread. I put a new PCS on, and the car still had the same not-starting behavior. I did the ECU reset procedure and voila! she runs like new.
