Then we went to a snow park with the kid, and I decided to do another test: The car stayed for about 3 hours within 25 F', I started the engine and waited about 2 minutes, observing the temperature...
* Nope, I haven't done the pressure test yet - this is the next step. ( together with testing the coil on plug packs & the wiring for grounding)
* As far as I know, the fuel filter is enclosed with the pump in the tank, so not really serviceable.
I just did the battery test yesterday, on a...
I wasn't familiar with that. But yes, the process flow is quite complex, so seems like hundreds of potential root problems exists.
One thing I remembered is that the previous owner(I'm the second one) changed the water pump at about 60K (Now 125K). I still have a very very little coolant leak...
* The spin speed seems the same, but once It gets into the firing stage, it starts "coughing slowly". Probably the sound is similar to the sound made when not enough gasoline is reaching to the system.
* I will have to check the fuel pressure with a gauge, but still I thought that if I wait...
