mpvoss Posted January 24, 2011 Share Posted January 24, 2011 I changed out the timing belt and now cannot for the llfe of me can not get the engine to start. Iam absolutly sure the timing belt is on correct. I have spark on all wires, have fuel also. I shot a microburst of starting fluid to see if the engine would start. No start. Cranks great. What to look for now? I'm stumped. Thanks for your input. I have search for the answer and am unable to get the results I need. Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted January 24, 2011 Share Posted January 24, 2011 just in case you are not sure about the correct timing marks. never the arrows!! Quote Link to comment Share on other sites More sharing options...
Ionlyhave3suubs Posted January 24, 2011 Share Posted January 24, 2011 (edited) The most common "no start" scenario when replacing timing belt on these engines is improper timing mark alignment. I have been sure I got mine right before and went back to find that I was a tooth off. Real easy to do on this DOHC design engine that the cams on the drivers side keep wanting to turn while you are putting the belt on as they are under tension. Whenever I do a Subaru ej series timing belt now, I always try to start it before I put the front timing covers back on. I always put the main accessory drive pulley back on the crank and the bolt back in first before trying to start it. It makes it a lot easier to take back apart if needed, and you can turn the engine back to TDC and re-check timing mark alignment in case of a no-start. For the crank alignment, you did use the notch on the back of the crankshaft toothed pulley lined up with the notch at the bottom of the crank sensor for your crank line up, right? I have seem some try to line up a notch on the main accessory drive pulley with the 0 degree timing mark on the outside of the outer, center timing cover. If your timing marks are right, check all of your sensor and other electrical connections. Sometimes these get disconnected while taking things apart and they get forgotten on re-assembly. Good luck! Added after reading above reply, the "crankshaft toothed pulley" I referred to is actually called "crank sprocket" in above diagram.

SchwarzeEwigkt Posted January 26, 2011 Share Posted January 26, 2011 This happened to me and it turned out to be that I forgot to plug the crankshaft position sensor on top of the oil pump back in. Maybe that's it for you too? Quote Link to comment Share on other sites More sharing options...
Cougar Posted January 26, 2011 Share Posted January 26, 2011 Checking the compression on both sides of the engine should show up a timing belt issue if there is one. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted January 27, 2011 Share Posted January 27, 2011 i know you feel like you got it but without seeing it first hand we have to say the most obvious and common things - +1 for alignment probably being out. did you remove the cam sprockets and did you reinstall them in the proper locations?

Luvn737s Posted January 30, 2011 Share Posted January 30, 2011 I think I counted 26 electrical, vacuum or coolant connections when I disassembled mine. How many are critical to starting, I don't know. Quote Link to comment Share on other sites More sharing options...
Cougar Posted January 30, 2011 Share Posted January 30, 2011 In case you haven't checked to make sure the ignition system is working yet you need to do that. Quote Link to comment Share on other sites More sharing options...
