duncan351 Posted November 30, 2019 Report Share Posted November 30, 2019 Long story short I had to pull my motor and rebuild it after spinning a rod bearing, So the motor was torn completely down and rebuild with same everything except replaced crankshaft, rods, & oil pump. Now the motor won't start. I have checked continuity on the cam sensor wiring Signal and sensor ground. which seems to me like its my trigger issue and They ohm'd out perfect they ohm'd out perfect. I have spark and fuel but spark seems to be firing 180* off all a sudden since reinstalling motor. I am including a few logs of me try to start the car. I can confirm the spark if firing 180* off by using my timing light. My offset is 200 which was perfect before. I have physically re timed the motor a couple of times just to make sure I wasn't off on my timing causing trigger errors and no difference. Any advise on what I should try next? My arming voltage was at .5 at 0 rpm's but I raised it to .7 see if that would help but it still firing 180* out while the cams are rotating and I use timing light.

ClintBHP Posted November 30, 2019 Report Share Posted November 30, 2019 Where is your pclr file, the cam sync seems to be a bit close to the missing tooth for my liking, try change the trigger edge see if that helps. Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 30, 2019 Report Share Posted November 30, 2019 It looks like your crank wheel has a damaged tooth. It has the normal 2 missing tooth gap where it is meant to, then another single missing tooth about 180° opposite that it shouldnt have. You will need to replace the wheel.

duncan351 Posted November 30, 2019 Author Report Share Posted November 30, 2019 Update: Adam, Thank you for your support. Once a part one of the teeth were broken off between taking it off and installation on the rebuild. Motor started right up. Now I know how to identify a broken tooth in the trigger scope. Thanks again for all your help. Link has to be one of the best supporting aftermarket ECU companies out there. Great support!!!! Quote Link to comment Share on other sites More sharing options...
