it means "One's own home is the best of all"
The fuel rail is right above the Intake manifold in front of the engine. To see it you might need to remove the grey rectangular plastic cover secured by two 10mm bolts on top of the valve cover. Otherwise just squint really hard; you will see the line leaving the rail right by the throtle body!
check fuseable links in wires located near the battery, they burn inside the insulation, so check them with a test light. peace on Fuel pump relay is bad, located under passenger seat or under truck under passenger seat? hard to find. I had the same problem on mine! The relay is on the passenger side behind the right knee panel (just under the dash on the right side immediately fwd of the door's fwd seam). A new one was about 35 dollars from the dealer. It is aplug and play affair and took about 3 minutes to knock it out. I've had multiple 720's with 'failed' relays. The relay itself is OK, but the connections to the relay on the circuit board fail. If you're adventurous, the fix is easy. After locating the and removing the fuel-pump control relay (see above) remove the circuit board from the black plastic box. The two connections on the circuit board that connect to the coil of the actual relay fail by cracking. They are located at the end of the relay with only two connections (the other end is the contacts and has three connections). If you look with a magnifier, the cracks are obvious. When the cracks are gone, the problem will be gone too. Resoldering mine fixed my problems permanently!
Didn't know there was more than one. The only one I know of is almost dead center underneath the vechial.
there is always a pressure release valve to remove air for fuel,location is usually on the right top of the motor where the fuel lines come in from the tank. the valve looks like the valve from your tire. just use a nail or something similar to press the valve and air will release then fuel will flow. and don't forget it has a cap.
