no power to fuel pump, no check engine light
hello all
I have two problems I think? I have a 92, 25th anniversary Z/28, 305 tpi. First, Saturday I changed my fuel pressure regulator. The car ran great, Saturday and Sunday, Monday it would only turn over, no start.
Second, I have no power to my fuel pump, I’ve changed all my fuses, as a G.P. non wore blown. I've also changed the fuel pump relay, and the fuel pump. Still no power to the fuel pump.
I’ve checked the red and orange wires, at the connector by the battery, I have power. The orange wire at the relay has power also. Third, I noticed today I also don’t have a check engine light when I turn the key to the on position. Are they connected? What am I missing? I need help please! !

mine was doing the same thing and it turned out to be a bad weather pack, the line from the battery going to power the fuel pump was bad, check to see if you get power to the orange wire to your fuel pump relay

Check for power at the fuel pump, make sure it is plugged in correctly, next trace the wires towards the front of car until you get to the relay. You have a break somewhere....
