I'm stumped got an 02 spectra with a 1.8 inj and fuel pump fuse have no power with the ignition on if I jump the fuel pump relay and put a 12v jumper to the inj fuse it runs what am I missing
Main EFI relay.
The pump relay should have four terminals. Number 2 is a green red wire which powers the pump from a 10 amp fuse. Number 3 goes to the pump. Number 1 powers the magnet in the relay and number 4 is the ground signal from the engine computer. If the relay does not engage on its own, one of these circuits is not working.
The injectors get power from that 15amp fuse which gets power from the main relay.
The problem could be farther upstream with the 25amp main fuse.

did you reset full cutoff switch? this will be located in the rear of the vehicle in the wheel well behind the fabric. in some cases they are located underneath the drivers seat.

try to locate the fuel pump relay. the pump should be turned on by the relay controlled by the computer. If you can't find the relay, to your local parts store, sometimes they have a component locator and can tell you exactly where it is.

needs looking at because it could be switch that allows it to turn on if sufficient gas is present ,or a problem with the clima compùter ,but to do anything you will need the special machine to empty the system then check things out so take to an authorised AC garage ,because these systems are a potential accident and you could lose a finger with frostbite in a matter of less than 2 seconds .therefore i will not tell you how to look for a soloution because of the dangerous nature of playing with air con
