car will not start Last year while driving the car it died an would not start, figured i spund a bearing because oil pressure was at 0, now motors all built, go to turn it over im getting no spark.>
Checked-
Fuses
Relays
Pin outs on harness
Swaped a ecu to see if mine went
Tested the crank sensor with a meter, its not getting any power.
I got nothing, im lost on what to do next.

As always seems to come up: Check the ground on the rear of the driver-side cylinder head. You would not believe how many times this gets missed. Other than that, get a wiring schematic, and start tracing every wire and verifying voltage (where applicable) and continuity. There's really not going to be any "short cuts" on this....you need to continue working the normal process of elimination.

Looking at the bcm, 1 of the 5 relays wasnt clicking on.
Looked close and saw a crack on the 'T' . Fixed that and still nothing.
I think my bcm is shot?

Do you get a check engine light with the key on? Plug a scanner in and see if you can communicate with the pcm. On some cars the fuel pump fuse also powered the pcm.

No codes are being thrown.
If i hot wire it, it wont die in 3-5 seconds? Cuz this is a new engine that needs the ring set
Is there any other way to check if my bcm is shot?

No signal,
Every sensor is getting power but injectors, cam, crank.
I looked at my wire harness. Its near my charge pipe but i dont think any wires melted.
Someone told me to track back the wires for. Ign 1 2 or 3. Because one of those control the cam crank n injectors
