Car won't start, no fuel pressure. Pump won't turn on. I've replaced the pump, crank sensor and checked the fuse and relay but both are fine. What other sensors could keep the pump from turning on? Also there is no security light when the key is in.
You DO realize that it only powers for 2 seconds when the key is turned on, right?
Have you tested for power arriving at the pump during that period?
Are you using a fuel pressure gauge to read the pressure?

Yeah I know, but you can usually hear the hum of it as soon as you turn the key. And theres nothing. I dont have a VOM to check the power, nor a fuel pressure gauge but nothing came out of the nipple on the fuel rail.

You're going to need some test equipment if you expect to pursue this problem yourself.
Can you follow a wring diagram to test the circuit?
