hard start issue
I recently put a new battery in the svx and after its been sitting for a few weeks in near freezing temps I decided to take the car for a drive,after several attemps of popping back out the intake and exhaust it barely started after it started to smooth out and warmup you can cut the car off and restart it with ease.But after sitting overnight I gave up this morning trying to get it started.One thing I did notice was that the fans was on while I was trying to start the car so I replaced the coolant temp sensor with one from a 91 legacy i found at a salvage yard,that was probably bad also because my car is still hard to start,I have some extra ignitors and will order a coolant temp sensor tomorrow.Any ideas let me know what you think.I got a few days before I get the parts so I will check the fuel system first and go forth from there.

Re: hard start issue
Sounds like you are on the right track with the coolant temp sensor. You should check for any stored codes to be sure.

Re: hard start issue
Yup, classic coolant temp sensor issues. When they fail or are failing, they cause the ECU to always see a warm engine condition, which includes not wanting to start when it is cold as it is not giving the right mixture for the cold temps. Also makes the fans turn on since the ECU is "seeing" a warm engine.

Another thing with a CTS that is failing, is you will get some bogging/surging until the car warms up on colder days. The only way to get OBD data if it is a 95 or earlier is with a Subaru Select Monitor as far as I know. Those aren't something the average person has but that would be one way to check. |

Re: hard start issue
Also I realized the coolant temp sensor I replaced wasn't the right one,after reading some older post I replaced the single spade connector and should have replaced the dual spade connector,I think I can round one up today.If that get me back up running I will perform a good cleaning of any sensor contacts I can get my wire brush on.
