jmoss5723 Posted May 12, 2016 Share Posted May 12, 2016 Phase 1 EJ22 had an idler blow itself apart and jumped time. While we had it all apart, we replaced all TB components, water pump, thermostat, accessory belts, and valve cover gaskets. Did an oil change, and coolant flush and replacement. Now it has a strong crank, but won't start. Just turns over with the starter. It seems like everything is hooked up. What am I missing? Should I just keep cranking and pray?

1 Lucky Texan Posted May 12, 2016 Share Posted May 12, 2016 (edited) you may have used the wrong mark on the crank sprocket - for belt installation, you ignore the arrow/triangle on the front. You use the tab with the dash/line on the back of the sprocket. also, did one of those tabs break off? the crank position sensor needs them.

Unfortunately, my brother finished up the TB change, not me. So I can't be sure without tearing the covers off and looking. Back to the garage, I guess.

987687 Posted May 12, 2016 Share Posted May 12, 2016 What year is it? if it's a 97 or 98 it may have bent the valves. I bet the timing belt is on incorrectly, though. 1 Link to comment Share on other sites More sharing options...

The car is a 96 with a non-interference engine. I'm betting my brother put the belt on with the crankshaft off 180 degrees. He's out there tearing it apart to figure it out right now.

Bushwick Posted May 12, 2016 Share Posted May 12, 2016 If he uses the correct crank pulley mark and has the cams aligned, it should fire assuming all is well. Link to comment Share on other sites More sharing options...
mikaleda Posted May 12, 2016 Share Posted May 12, 2016 Probably just didn't get it right the first time, it happens. I'd pull the covers off and redo it and see what happens. Link to comment Share on other sites More sharing options...
jmoss5723 Posted May 13, 2016 Author Share Posted May 13, 2016 He was sure that he set the timing right. He pulled the covers and reset the timing, still nothing. We pulled the plugs and they look pretty bad. We'll install some good plugs and try again, but it would be a little bit weird that it ran fine before the timing failure and now the plugs are suddenly so bad that it won't start. So I'm betting the plugs are not the problem. We're also going to change the fuel filter to see if maybe its not getting enough fuel. Low fuel AND low spark AND TB failure would be quite the coincidence, but I guess anything is possible. Link to comment Share on other sites More sharing options...
mikaleda Posted May 13, 2016 Share Posted May 13, 2016 (edited) Your positive its a non-interferance motor? A compression check might not be a bad idea at this point. Edited May 13, 2016 by mikaleda Link to comment Share on other sites More sharing options...
987687 Posted May 13, 2016 Share Posted May 13, 2016 96 is a non-interference, I had the belt break on mine going 80 on the highway with no damage. You can count the teeth between between timing marks. With all the timing marks straight up. From the crank mark to the passenger side cam mark, there should be 44 teeth. From the crank to the driver side cam there should be 40.5 teeth (yes, it starts on a groove and ends up on a tooth on the belt). This will ensure you have the belt on correctly even if it's marked incorrectly. At this point, you need to start checking the engine vitals. Pull the injector harness plugs and using an oscilloscope or noid light check to make sure they pulse when the engine is cranked. Check to make sure you have fuel pressure. Check spark at all cylinders. You might have bumped a connector on a cam/crank sensor that's causing all your issues. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted May 13, 2016 Share Posted May 13, 2016 (edited) I'd spray some starter fluid or similar into the intake to see if it fires - that should help with questions about fuel. make certain the crank position sensor is undamaged and plugged in. any CEL codes?

mikaleda Posted May 13, 2016 Share Posted May 13, 2016 96 is a non-interference, I had the belt break on mine going 80 on the highway with no damage. But how do we know the motor wasn't swapped out with an interference motor? Its always a possibility and it only takes a few minuets to do a compression check. Ive had it happen, you just never know unless your the original owner. Link to comment Share on other sites More sharing options...
winginit Posted May 17, 2016 Share Posted May 17, 2016 same thing with the 96 ej22 i am working on. previous owner took it apart to change cam seals put it back together and wont start. it will start after resetting the T belt. everything has been changed. I smell gas when its turning over. either in the intake does nothing. did you fix yours ? thanks Link to comment Share on other sites More sharing options...
