Casull Posted August 12, 2015 Share Posted August 12, 2015 (edited) Howdy, My Subaru won't start all of a sudden. I am new to this car, so bear with me. I will explain what I have observed. Upon turning the key to a point the lights turn on the fuel pump in the rear makes a "Rrrrrrr... Rrrrrrr" Sound with about a one-and-a-half second pause between sounds. This happened before but the car would start and then there would be a constant "rrrrr" sound. There was a situation not so long ago where I cranked for a while longer than I'd like to, and it did start. The fuel pump and fuel filter look brand new. But my first assumption to this point is that I must have been too low on gas and they got gummed up. However, I must consider than the sound is normal. Again, I'm a newb. Did a firing test. Definitely firing. Suggestions, ideas, knowledge? Update 1: After letting the starter attempt to do it's job for about five or six seconds the car did start and does start every time after. However, I do not know if that means the problem is somehow solved. The idle itself on the first rough-start was fine, but became more adequate all of a sudden with a higher RPM. I will be doing a cold start soon to see if I experience the same difficulty.Update 2: I let the fuel pump oscillate two to three times before attempting a start. After actually running or being on a trip it starts right away. The short (if there truly was one) is also gone. I have not experienced difficulty to start anymore. I assume it was dirty fuel causing inadequate pressure. But really, I don't know. Edited August 20, 2015 by Casull Quote Link to comment Share on other sites More sharing options...
jono Posted August 12, 2015 Share Posted August 12, 2015 fuel pump may look new, but is it ? Got factory part numbers on it ? I suspect you have a spfi - throttle body fuel injection ? The efi fuel pumps don't last forever if original, can do with a tap from a hammer either before or during start attempt Quote Link to comment Share on other sites More sharing options...
Casull Posted August 13, 2015 Author Share Posted August 13, 2015 Thank you. So far so good today. I also have an interesting dilemma. My AC/HEAT controls are mostly unmarked. Anyone have a photo of any that are in tact? I have a feeling mine has no "off" button like I've seen...I will update the main part of the thread as I discover more about what is going on. Largely good to go through today after keeping it going and all. Quote Link to comment Share on other sites More sharing options...
Casull Posted August 20, 2015 Author Share Posted August 20, 2015 I have updated the thread. The problem seems to be solved by allowing the fuel pump to work a little. Read more in Update 2 of the main post. Quote Link to comment Share on other sites More sharing options...
