Okay, so after spending some time learning about relays and going back over the instructions, I have finally figured it out. This is a lot to explain but I'll try my best. Basically in shorter terms, the factory EEC power relay is non-existant and the painless harness EEC power relay wasn't getting the constant power that the computer and relays need allowing the trigger wire to turn the relays on and off like normal. For the Hissing noise from the fuel pressure regulator, I removed the vacuum line off the tip and the adjustment screw came off with it. I think the adjustment was at the least amount of pressure possible allowing the fuel to just go back into the return easily. I threaded the screw in a decent amount and now the hissing is gone.
Being that both the factory fuel pump relay and painless harness fuel pump relay were hooked up at the same time. Both had Constant and key-on switch wires attached like normal with power going to them but, my factory EEC power relay was removed when I eliminated the old engine harness. But the new painless harness has an EEC power relay and I know both the fuel pump and EEC power relay connect. Since finding out relays have a constant 12v and a key on switched wire going to them I checked for constant 12v power on the painless harness with a voltmeter at the fuel pump relay and had nothing. I then traced down and figured out that I mistook the wire labeled "starter relay" for the ignition trigger wire and placed it wrong. This yellow wire is labeled
STARTER RELAY: This is a yellow, open ended wire. Connect this wire the the B+ side of the starter relay or to the positive side of the battery. This wire provides constant Battery 12v power to your computer and relays. I attached this wire to the middle threaded part of the starter relay, which wasn't providing the constant power to the fuse box, computer, relays, and wasn't providing the signal to the trigger wire to turn the relay off. After placing the starter relay wire in the correct spot I checked the painless harness for constant power and key on power at the relays and fuses and everything checked out. I then checked my green/ yellow trigger wire when I switched the key on with a volt meter and the numbers blipped and went down as a trigger wire should. I then disconnected the factory pink and black fuel pump wires from the factory fuel pump relay and hard wired the trigger wire to it and my pump primed for 3 seconds and shut off like normal and I even had the car running and idling.
Thank you everyone for the help. This was just me kinda-sorta rushing through the installation and not reading the fine print in the instructions given and just going off of the labels taped on the wires that painless has.
Voodoo cams cost a lot to get that sound.
