New ecm and no start
Ok. I’ve been fighting a no start issue The last couple weeks after doing a firmware update. Borrowed a new ecm, downloaded the software for it, redid a new tune file for it, did a tps autoset, have tried a new crank and cam sensor car still won’t fire. Prior to these issues the car ran for 3 seasons. Ran 5.40s with a sbe 6.0. Car cranks fine. Tach says sync, then will flash a rpm usually in the 700-900 range which is way higher then it’s actually turning then will say error and keeps repeating that sequence. I’ve replaced everything short of the harness itself. Any thoughts?
