Why does my Subaru Impreza stall when cold?
It starts just fine and idles smoothly when cold. It also drives good, great in fact when the engine is still cold – it accelerates smoothly and with plenty of power, but the second the temp gauge starts to move it begins idling rough, missing and loping and now it will even stall out and become very difficult to restart.
Why does my 2005 Subaru Forester not start?
My 2005 Forester has similar problem. No crank when failed to start warm. OK after a while. I heard it was a “shift linkage” problem that somehow “the computer returns a message as the car is in gear hence it doesn’t start when the key is turned in the ignition”.
Why is my coolant temperature sensor not working?
If a warm car continues to turn over and not start (assuming everything else is working correctly), the coolant temperature sensor is the culprit. Also you should be able to unplug it and the car should start as normal. If removing the sensor from the equation fixes your problem – then thats a solid diagnoses.
Why is the fuel pump not working in my Subaru?
Corrosion is resistance. loose pins at the plugs mean sporadic outputs or operation. Check them. Fuel pump could be running great and supplying sufficient fuel a for cold running engine and then as it heats up, with the engine, expansion of the metals in the pump or module reduces the pump output.
Why does my Subaru keep bucking and stalling?
Fuel is a tricky thing. If you buy cheap, you get cheap. If you buy a major brand gas, or a station that has a major brand label/sign, and the station doesn’t see a lot of fuel traffic, water can be an issue, or the settlement of alcohol on the base of the tank is finding its way in to your tank. Bad grounding and/or conductivity.
Why does the ECM slow down a Subaru?
If the systems do not have enough electrical flow for use, you get a dumbed down car. Think in relationship to a laptop or cell phone with a low battery, it slows down. Same with the ECM. And if the electrical flow is low, solenoids and switches will either work poorly or not at all.
Where does internal combustion occur in a Subaru?
The cylinders encase the pistons, where internal combustion occurs, therefore this is the part of the engine that receives the most abuse. The cylinder walls are exposed to explosions with high heat and impact, and expand and contract when the engine is on and off.
What do you need to know about a Subaru engine?
The complete engine is what comes out of your engine bay in its entirety. It is everything, minus the intercooler, piping, hoses, and fluid reservoirs. Also known as Turn-Key.
What causes a Subaru to run pig rich?
If the sensor is constantly telling the ecu that the coolant is too cold and placing the engine in “warm up mode” even when the engine is at operating temp, it will cause it to run pig rich when it is unnecessary, like driving an older car with the choke open constantly.
Why does my Subaru a / C blow cold and then warm?
If I turn it off to go into a store or something, it’ll still blow warm, only gets cold again if it’s off for a while. It’s a 2015 with 88k and I’m out here in the desert of SOCAL, I thought maybe it running low on Freon, so hooked up the can of ac fix but the gauge displayed good pressure right away To rule that out.
