So I installed the new walboro 450 on sunday. And car still wont start or get fuel pressure (regulator is reading 0)

I am at a complete loss. I have an aem fuel pressure gauge which I havent installed yet. As well as a new diaphragm for my apr that I havent installed. (Didnt want to change to much at once)

I unplugged the fuel line and no fuel comes out. I've checked the wiring with my multimeter. I get power all the way to the connector inside the tank that attaches to the pump itself(however i have not tried the other end of that connector as i dont want to open up the wires etc). But the pump doesnt turn on when i power it up via link.

Any ideas on what's else? Only other thing I notice is 3 of my 4 aem gauges dont stay on while cranking where as they used to, and every time the car ever cranked and fired up those gauges stayed on.
