Hello all. I have a problem that has been driving me absolutely nuts.
I have a built 6.0 LQ9 running a SD Open loop tune. It has been running for about 6 months now with no issues until now. The car turns over and it seems to want to start up but it does not fire up. We tested for spark using the in line spark tester and it does not have any spark. We changed the crank sensor to a brand new one and same with the crank sensor. Also checked the injector pulse with a noid light and the injectors seem to be working fine. Also, we tested for power at the coil packs and the coil packs are getting power through the pink wire in every single one of them. We tried to put on different coil packs and still the same problem persisted. We even checked the ignition relays and swapped them with fan relays and no luck. Even tested the relays to make sure that they worked and they seemed fine as well. Fuel pressure is also good. Reading around 55 psi at resting and 53 psi on cranking. I am at a total loss on where to even start next. Attached is a log file that i took when cranking the motor over but not starting. Maybe you guys can pick something up that i can't. I need some big help here. Thank you all in advance.
