I've got a 99 Legacy Outback (30th Anniversary edition) that just flat out died while driving on the interstate. No previous problems or symptoms. Car turns over, just never starts. Note: The check engine light is not on. I've run the diagnostics, and gotten no codes. Here's what I've done: * I believe it's not getting spark (by spraying starting fluid and still nothing, also I can hear the fuel pump switch on and I pulled the fuel line and am getting output). * I put on a new coil pack - no change to the symptoms or status. * I took my ignitor and put it into another car. Other car performed fine. * I took out the crank sensor and the cam sensor to test them. They appear to be functioning fine. * I took out the ECU and put in one that I know to be fine - no change to the symptoms or status. *** Note: I found it weird that the car had the same symptoms regardless of whether an ECU was hooked up or not. Now, where do I go from here? Timing? Also, please know that about every fifty attempts at trying to start it, it sounds like it gets close to catching at the initial key-turn, but then nothing. Please help.
RetiredGearhead posted a topic in 1990 to Present Legacy, Impreza, Outback, Forester, Baja, WRX&WrxSTI, SVXI swapped a 97(?) JDM 2.5L in for a 99 2.5L recently. The 99 was driven about 60 miles with no water in it due to a blown hose, nuf said, it wasn't me. I installed the "new" older 2.5 with new timing belt blah blah blah. Timing set up nicely. Even though the JDM was injected, we transferred the inake and other appropriate items to the "new" block including drilling and tappping out the EGR hole in the head. I don't want to go into the 4 bolt vs 8 bolt "bell housing" issue as it doesn't seem to be an issue. Where my problem is at, is that I can get spark to the cylinders #1 and #2 but get no spark to #3 and #4. The coil(s) check out, the ignitor checks out and there doesn't seem to be a signal from the ECU to fire the #3/#4 ignitor circuit. I have checked the wiring between the ECU and the Ignitor and it appears OK. The connector at the ECU is clean and undamaged. So I assumed it was the ECU as I have read that it is the main source of "no start" conditions. I put in a used ECU. I got exactly the same deal, no signal to #3/#4 circuit in the ignitor. I find it hard to believe that a second (albeit used) ECU would have the same problem ........ or does it? What would cause the ECU to send signals to fire the #1/#2 circuit but not the #3/#4? I am baffled but it is probably something simple. Any help? I am new to this site and this is my first request. As far as my background. I have degrees in Electronics and Mechanical Engineering so I am no ametuer at troubleshooting and I am pretty much down to earth in that degrees don't mean spit sometimes. I usually find the simple things are the ones that trip us up.
