LT1 wont start

[turnerracing]

My car just crank. I have fuel pressure and spark but no injector pulse and there no codes. I've replaced the opti with a mad one and tried another pcm I got from a junk yard. Anybody have an idea why injector are not getting the ground signal because the pink wire hot.

Have you tried spraying some starting fluid in the intake to be positive it's not getting fuel?

I got it to start today but I dont know what I did. I shut it of and retried it. It was hard but got it to start again. Then I let it sit and tried it again and no go. I havd injector pulse know but the fuel pump prime to 47psi then drop to 35psi and hold there is that normal.

If its not running..fp blleding off is ok. Although if it instantly drops to 0... That is not.
