LS3 No Start
I am having an issues starting a LS3 swapped into a 95 BMW.
Harness is from PSI. I reprogrammed the PCM.
Fuel pump is running both when priming and also when cranking. But no fire at all. Not even a sputter.
When I scan while cranking I do see around 125rpm so that tells me the crank sensor is working.
I have not checked for spark yet or used a noid to see if the injectors are get a pulse.
But when I pull a plug I am not smelling fuel at all.
Fuel pump is running and I have fuel up to the rail. I have not checked pressure yet tho. I need to get a tester.
In HP Tuners I set VATS 1 and 2 to disable and did a write entire.
It seems like the injectors are not turning on.
When I scan DCTs I get
P0315 - Crankshaft Position System Variation Not Learned
What can I check next?

I haven't scanned for that yet.... Should I just add "Cam Sensor Counts" ? Or something else?
