In this diagram, the asd relay supplies voltage to fuel pump. See the red wire, hot all the time, protected by fusible link. Use a test lite check for voltage on that wire? If it is hot, unplug the asd relay use a jumper wire on load side of relay, the load side is that line with arrowhead. Use a jumper wire between red and dark green wire terminals, if the pump runs, hopefully it is ok. The problem would be on control side of relay, right side in picture. The control side of relay needs both voltage and ground.
Any applicable trouble codes?
if it did not have an electric fuel before then the installation of an electric pump is a relatively easy process. If you have an electric pump already fitted but it has failed then remove it and install the new pump in its place. Take care to check all wires, fuses and relays and any pressure sensors for correct operation. Remove and blank of the opening for any mechanical pump on the engine
For new installation select an easily accessible place under the vehicle that can be protected from flying rocks and road debris. Run a power wire (red colour) from the run side of the ignition switch to the relay ( to be fitted ) near the battery or in the engine bay. Run this wire through an inline fuse close to the ignition switch to protect the circuit. attach to a coil actuation terminal of the relay.( look at the base of the relay for terminal identification. Run a black wire from the other side of the coil actuation pin on the relay to earth. Normally the same bolt that mounts the relay. Run a red wire capable of carrying 20 amps directly from the battery terminal through an inline fuse ( close to the terminal) to a power pin on the relay. Run another red wire from the outlet power pin on the relay to the electric pump. . Run an earth wire from the pump to earth.
This is a basic electric circuit for the installation of the pump. If there is a requirement for a pressure regulator or pressure sensor to control the pressure or pump operation , that control wire will be connected in series into the wire from the ignition switch so that when the pressure is reached then it breaks the circuit to the relay from the ign. switch and the pump will stop operation until the circuit is again completed. When the ignition switch is off there will be no power for the pump
a fuse of this size may be the ignition fuse or a fuse that powers high power draw units , fuel pump lights etc. However if it blows immediately then you have a dead short in that system like a failed relay or solenoid or a wire ribbed through or pinched shorting to earth. Carefully check wires from this fuse and look for the same colour coded wire on relays ,ignition switch starter solenoid etc.
For that you will need to be able to do some serious wiring. You will need to find a relay in the engine compartment fuse/relay box that turns on when you turn on the key, like the electric fuel pump relay, for example. Next you will need to calculate the amperage draw of all of the lights you are going to hook up. If the fuse for the relay you chose is smaller than the amperage you need to serve both the fuel pump and the lights then you will need to make a fuse connection at a spare in the fuse box to connect to the new relay output and input (see below). The fuel pump relay has control and supply wires on it. The supply wires actually supply the power to the fuel pump. The control wires simply turn on the relay when you turn on the key in the ignition. You need to hook up the control wires of the fuel pump relay to the control wires of the new lights relay. As stated earlier, the supply wires are then hooked to the relay and, in turn to the supply fuse. Make certain that you use some heavier wire for the supply circuits. Thinner wires may be substituted for the control wires. Solder at the fuse box side and use spade connectors at the lights side...good luck!
connect the positive wire to the ignition wire ,, so it only turn on when you ignition turns on.. if needed for an emergency run it directly to the battery.
The fuel pump relay is located on the frontof the engine compartmant on the passenger side of the radiator support. they are right behind the right side headlight. they are the oval looking style relay with a white diagram printed on top. The fuel pump relay will be he one with a black,green,grey and red or orange wires going to it. if you suspect it is bad check the wiring in that vicinity first for a break in the insulation usually accompanied by some green corrosion. The grey wire is the wire that goes to the fuel pump. The green wire recieves a ground signal from the computer for 3-5 seconds when the key is turned to the on position and is ground all the time that the car is running. the fuel pump fuse is also located near the relays. you have to remove the fuse from the holder to check it. Good luck! Scott
Are you getting battery power and ground at the fuel pump connector? (This should have been checked BEFORE replacing the pump)
Other things to check:
1. Fuel Pump relay in the Engine Compartment Fuse Block
2. The relay is powered (Secondary -or- "fuel pump side") by Fuse 0 in the Engine Compartment Fuse Block.
3. The relay Primary -or- "control" side is powered by Pin 37 RED wire at the PCM
4. The relay Primary control (or ground circuit) is operated by Pin 22 LIGHT BLUE/ORANGE wire at the PCM
5. The Inertia Fuel Shut-off Switch located between the fuel pump relay and the fuel pump may need to be reset. The switch is located behind the right kick panel. The DARK GREEN/YELLOW wire at the switch is the feed from the fuel pump relay. The other wire goes to the fuel pump. Some units have the DARK GREEN/YELLOW wire going in and the wire going out can also be DARK GREEN/YELLOW, or PINK, or ORANGE - the wiring diagram for your vehicle does not specify the color of the wire that actually goes to the fuel pump itself.)
6. If none of the above produce any results, make sure that your ground wire at the fuel pump has good continuity to ground. It usually screws to the left frame rail near the fuel tank.
Any of these components (including the PCM) or their connecting wires could be the cause of your problem.
In the engine bay there is a inline fuse holder with a red wire going into it(and out).It runs to a relay.Standing looking into the engine bay,these are on the left hand side.This relay is for the fog/running lights only.Check the inline fuse.make sure the relay has power and then check the relay is 'clicking.1st thing though is to make sure all connections are tight and clean.Its a short easy to follow set of wires and nothing else runs off this circuit so it is easier to see problems than most elect, problems.The wires from relay to light will be red/white.Hope this helps
fuel filter? how about power to the fuel pump,loose ground wire to chasis? wiring harness? terminals clean at point of connection?did you check the fuel pump relay? Relay is located in electrical center under the hood on the driver side.relay and fuse legend will be on bottom side of cover, you sould be able to switch with another relay that you know works, ie: switch horn relay with fuel pump relay, honk horn to insure both relays are working when either relay is inserted into horn slot. Do you by chance have the electrical schematic drawing for the fuel pump?
