starts hard when cold

[Peterlegacy]

I have 1993 Subaru Legacy wagon ---Anything below 45
to 40 degrees I have a real hard time starting this car. I've replaced
plugs and wires the fuel filter and was thinking it might be the fuel pump
? Check engine light is still on . Could this be a sensor ?
Starts fine in the summer.

Thanks
Peter

quite possibly the temp sensor. Not sure on a 93 but likely to be a
seperate sensor from the coolant sensor. Basically, the ECU doesn't go
into 'choke' mode at low temps.

Could be a lot of things.

Get the CEL code pulled and come back.

Carl's right on the money with his suggestion.

Do you have a check engine light?
If so, there are diagnostics connectors under the dash that will enable
to read the error code. If it is the thermo sensor, you can reset the
code and the car should start normally again (until the next time you
need to start it cold, that is). This is only a temporary fix, as you
will still need to replace the thermo sensor.
For the procedure, see http://www.troublecodes.net/Subaru/
