i checked all the relays and fuses on the car (http://zilvia.net/f/#) and they all worked fine i took out the fuel pump and i tested it with a battery and it worked fine i put evrything back together and my car wont start.
so far what i noticed is that i have no power going to the fuel pump cuzwhen i turn the power on the fuel pump wont turn on for a sec as it should
once agin im clueless all the relays and fuses r fine but when i checked the power plug from the fuel pump my test light shows theres no power going to it at all so does anybody have an idea y its doing that?

THANKS A LOT FOR THOSE WHO R HELPING ME!

Just becuase you test the fuel pump with power and it spins doesn't mean its good, you need to test it with a fuel pressure gauge.

See if you have power at the relay, fuse, and then the harness at the back. Should be able to figure out, from there, where your prob is.

Make sure the wires have a good solder at the pump, yank on the wires, make sure they stay connected.

Try using a different ECU, or making sure your ECU is plugged in tight.

I had a bad ECU and my fuel pump wouldn't prime.
