ehsnils Posted June 20, 2013 Share Posted June 20, 2013 So, there's good news today. After testing for continuity, and running ohms through MANY wires, I found a broken wire that led me to think that I got the ECU and the BIU talking again. I trailered it to the Subie dealer today, and we reflashed the immobilizer. FIRE! Whoo hoo!! Well, more like sputter. I turn the key and it sputters for a few turns but never runs. Remembering, this is a brand new engine- is there anything I am missing? I have fuel, and I have fire... but not a constant running car. I get a few sputters, but nothing sustained. Last chance?? Any advice?? Check all timings so that you have the right timing and also so you haven't mixed up the firing order to the spark plugs. Wrong order to the injectors should still allow the engine to run. Link to comment Share on other sites More sharing options...
SBT Posted June 20, 2013 Share Posted June 20, 2013 Electronic nanny working properly ?Compression ?Fuel ?Air ?Fire ? Obviously, if 1 isn't proper, then 2-5 aren't going to work properly either. If you have compression, then valve timing should be close enough to run, but could still be out. Check the timing belt to make sure everything is as it should be there. Fuel pump getting signal from the ECU and firing at the proper speed and pressure is critical to starting and running. ECU needs input to know when to fire the injectors as well. Air - If the ECU is reading the signals correctly from the crank and cam sensors, and the Throttle Body is correctly connected and feeding info to the ECU, then it should be reading everything correctly there and "air" should be happening Fire - Again, ECU reading sensors correctly, and sending spark control the proper sequencing on the coilpacks. It's all interdependent. - Pro amore Dei et patriam et populum - Link to comment Share on other sites More sharing options...
CaptainGVT Posted June 20, 2013 Author Share Posted June 20, 2013 I have checked the timing belt, and I think I may be a tooth or two off on the passenger's side, and 2-3 teeth off on the driver's side. Tomorrow I will try to remedy this. Does anyone think this small variance could be the cause of my sputter/no run issue. ECU to fuel test is good. Cam and crank position sensors are receiving pulses and sending back to the ECU- maybe just not at the right time. Coil packs tested positive, so I am hoping I have found a smoking gun. Wish me luck.

frank_ster Posted June 21, 2013 Share Posted June 21, 2013 If a cam is out of phase the ECM won't let It start Just so you know Subaru timming is done 90 deg from tdc just incase you thought it was like a normal engine. I made that mistake! Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...
frank_ster Posted June 21, 2013 Share Posted June 21, 2013 With data logging can you see rpm in the data log ? Can you see injected pwm? Is the fuel pump being commanded ?

CaptainGVT Posted June 24, 2013 Author Share Posted June 24, 2013 Through the weekend I discovered that only driver's side of the engine has spark. Another step sideways. Hmm. Link to comment Share on other sites More sharing options...

CaptainGVT Posted June 25, 2013 Author Share Posted June 25, 2013 Cam gear is off?? Care to elaborate? Timing belt is off a tooth? We checked the timing belt, cam gears, main crank, marks, etc. as per the manual- and all has been put right. I have ordered a cam position sensor, and we will see if that helps. Wish me luck.

frank_ster Posted June 25, 2013 Share Posted June 25, 2013 Car will run with the cam sensors unplugged they are there for sequential fuel injection timming and can advance timming. I you have two coil packs firing and two that are not I would say the timing is correct there is another problem either wiring or the coil pack them selves Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...
CaptainGVT Posted June 25, 2013 Author Share Posted June 25, 2013 Replaced the passenger's side cam position sensor- got fire... roared to life! Wow, what an adventure it's been. Now, to button everything up, start clearing codes- and drive the wheels off of it. Link to comment Share on other sites More sharing options...
frank_ster Posted June 25, 2013 Share Posted June 25, 2013 could you just try unplugging both cam sensor s and see if it starts .. it would require the engine to crank for about 5 seconds. it wont start right away.

subymike77 Posted June 25, 2013 Share Posted June 25, 2013 Probably the most interesting thread I've found on this sight. I thought I was the only one who wanted to do this to a 956. Link to comment Share on other sites More sharing options...
