Adamw Posted June 18, 2020 Report Share Posted June 18, 2020 When you say it "wont start", can you give a bit more detail - are there any signs of life at all - cough or backfire or anything? Do you have realistic and stable RPM in the software when cranking? Can you do a short PC log of it cranking: https://www.youtube.com/watch?v=_P1LRANeO4A Quote Link to comment Share on other sites More sharing options...
Nate Posted June 18, 2020 Author Report Share Posted June 18, 2020 It's to the point it almost wants run but then dies out to a flat motor turning over repeatedly. But I'll try to get log Log 2020-06-18 7;18;55 pm.llg Quote Link to comment Share on other sites More sharing options...

Adamw Posted June 18, 2020 Report Share Posted June 18, 2020 Looks like you have some trigger issues. Can you do a triggerscope while cranking. Here's how: https://1drv.ms/v/s!AiYbYlZQuRHPmidU5V2CmTcv6t2y?e=jewJ26 Quote Link to comment Share on other sites More sharing options...

Adamw Posted June 19, 2020 Report Share Posted June 19, 2020 Nope, I dont think you have done that right. Make sure the engine is cranking when you click the capture button, and keep it cranking for 5 seconds or so after. Quote Link to comment Share on other sites More sharing options...

Adamw Posted June 19, 2020 Report Share Posted June 19, 2020 Yep, you got it this time. I cant beleive I have seen this twice in a week now, but you have a damaged trigger wheel on your crank. It has some teeth missing somewhere about directly opposite to where the normal missing teeth are meant to be. Same as this guy here, he says his had rusted off: Quote Link to comment Share on other sites More sharing options...
Nate Posted June 19, 2020 Author Report Share Posted June 19, 2020 Dang it man!!! Thanks Adam for the feedback I will get on it and see if there is any damage to that wheel This was a full rebuild so not to happy I gotta go that far backwards but the time and money that's been invested I'm on it Quote Link to comment Share on other sites More sharing options...
JMP Posted June 20, 2020 Report Share Posted June 20, 2020 kind of common for people to damage the teeth on JZ crank sprockets when they remove them but dont remove the tab on the intake side of block first, usually ends up ripping the trigger wheel off the back of the sprocket Nate 1 Quote Link to comment Share on other sites More sharing options...
Nate Posted June 21, 2020 Author Report Share Posted June 21, 2020 Adam, appreciate that info you was right on Quote Link to comment Share on other sites More sharing options...
JMP Posted June 22, 2020 Report Share Posted June 22, 2020 The missing tooth looks to be in the same position as the retaining tab when the keyway is facing straight up Nate 1 Quote Link to comment Share on other sites More sharing options...
