hard starting when cold
Took my 94 SVX to the local mechanic because the car has developed a problem starting when it has been left in the garage over night. He couldn't diagnosis the problem because the car is too old for his diagnostic equipment and he recommended I go to a dealer. I've had a similiar cold start problem in the past, w/a Volvo and it was the cold start injecter. Any suggestion as to what to check?

In the mean time, I would fit a new Temperature sensor. Its the one with two wires, on the water crossover pipe under the left hand side of the Inlet manifold. Harvey.

Re: hard starting when cold
Temp sensor is a easy first step

Re: hard starting when cold
Make sure the car is quite cold when you change the temp sensor. Otherwise you'll get sprayed with hot water when you take the sensor out. The sensor is cheaply available from rockauto.com.

Re: hard starting when cold
I agree with the temp sensor, however get an OEM subaru sensor. They are only a couple dollars more than some of the cheapest aftermarket, and actually cheaper than some aftermarket. I have seen some of the aftermarket sensors not work properly with the SVX ECU.

Good to know. Got a part number?

Re: hard starting when cold
Thanks for the info. I'll do that as a first effort. My usual mechanic was "older",and retired after 3 strokes. I need to find another mechanic who will work w/me on mods and is more flexible. The car also needed a NY state inspection and he wouldn't pass it because the headlights are yellowed. I don't think that's a failable issue but rather than argue (which I wouldn't have won), I will polish the headlight because they do need to be polished.

Re: hard starting when cold
Still need help w/cold starting problem. I installed the OEM Subaru temp. sensor (very easy) but I still have a problem starting when cold. The engine cranks over immediately but it takes a few seconds of cranking and the engine tries to start. Some times it will start and run rough for a few minutes but now that the weather is colder, the battery dies before the engine will fire up. I've eliminated the temp. sensor so what would be the next step? I had an older Volvo which had a cold start problem caused by a "cold start injector". Do we have something similar?

Re: hard starting when cold
We do not have a cold start injector.

Re: hard starting when cold
Is the battery sufficiently charged? time to swap it?
Did you try giving some throttle after 3-4 cranks? It's down to -15 celc here, I have minor issues and blame the fuel transfer system, from pump to injector. A small tap on the pedal usually does the trick if there's serious problems. Mine does start but rpm goes to 1400 rather than usual 2000+.. might rise eventually or might just hang around at one point rather than settling slowly down to it's usual 500. This does not happen when the engine is warm.

Re: hard starting when cold
Brand new battery and I replaced the temp sensor located at the back of the engine, driver's side by the intake in the lower water crossover, as instructed by earlier posts. Tapping the throttle (gas)peddle or holding it down makes no difference. The engine will crank until either the battery dies or it starts running rough (Think just from too much gas while cranking), then it settles down to normal running when the excess fuel is burnt off. It will start normally after this for the rest of the day unless left off for a long time. Then the hard start reappears.
