SOURCE: We are replacing the fuel filter in a 98 pontiac

Assuming you mean replacing the fuel PUMP, the 2 wires are different guages. Connect the lighter wire to the lighter wire and the heavier wire to the heavier wire. If the new harness uses both the same size wires, the heavier wire on the vehicle side (solid black) is for the fuel pump ground. Lighter wire is for fuel guage sending unit.

SOURCE: I tried to install a new head unit it. cut the

First lets start by disconnecting the battery. Then go through each wire you reconnected. I'm not sure what process you took to connect them. Taping, wire caps, etc.... Anyway make sure these wires are connected firmly then move on. If you got a spark I could see there being a blown fuse somewhere. From what I read you are saying there is not burnt fuses, but I'm not sure if that is what you meant to say. If this is the case you could have a bad wire. If the fuses are fine and make sure you thoroughly check them for any problems. Could be a very small imperfection causing the lost of connection. Next move onto to testing the wiring. Reconnect the battery if you have made sure all wires are safely connected and fuse is back in panel. Take the wire tester and find the ignition and constant wire. When the key is on both of these wires should be lit up. When you turn the car off, one of these wire should be off. This will indicate that you have proper electrical going to the unit. After getting through all that, check the ground wire. If this is bad you get not life from the unit. There is a lot here, but it could be a couple things causing this for you. Hope this helps and good luck!!

How do I fix my gas gauge in my 1989 ford crown Victoria ltd?


Nine times out of ten, it is the sending unit in the tank that is the problem. To check, use a sort jumper wire to ground the gas gauge wire to the frame while watching the gauge needle on the dash, with the key in on position.

Find the gas tank electrical connector by the tank. Pull it apart, and on the harness side of the connector, locate the wire going to the sending unit. I don't know what color it is, but the fuel pump wire is a pink wire with black stripe and there is a black wire for the ground. The other wire should be for the dash gauge's sending unit. Have a helper turn the key to on and watch the gas gauge for any perceptible movement while you use the jumper wire, insert one end into the terminal for the gauge's sending unit wire (this is on the harness side of the connector, not the gas tank side), and touch the other end to the car frame-you are grounding it. If the dash gauge is good, the needle should move a lot, usually will move more than half way, one way or the other. So if it does, you know the dash gauge is good, and the problem is in the sending unit.

If it is the sending unit, it is quite a job to drop the tank, pull it out from under the car, then pull the fuel pump and sending unit out. You might be fighting a lot of rust on an '89-get some penetrating oil. And look for the removal procedure in a repair manual. It's not terribly difficult if you are handy with tools...and like to get dirty. Those hoses on the tank have been stuck on there a long time. Good luck.

My wife and Step son, did me a favor, and changed the plugs in my truck. Now my oil pressure gauge is reading above half at idle and pegs out at 1500rpm. Did the pressure switch go out or could it be a...


The sensor has gone bad, it's common since the housing is made of metal and the center is made of plastic. IF you go to Auto Zone they will have the new oil sending unit and  can give you the step by step instruction to replacing it. You can check the wire harness on the oil sending unit to make sure it's has not come loose and not getting full contact first. Good luck and hope this helps. Take your cover off like you are changing your oil. If your feet are sticking out the front of the truck, it will be to the left of the oil filter location, but immediately. There will be a wire harness and a plug. You can't miss it if you use these crude directions.

Fuel tank wire harness


My schematic lies to me a lot but here it is: dark blue:goes to gauge, dark green with red stripe is pump power and black is ground.
Hot wire should have 12v, dark blue should have pulsing voltage and black should be absolute ground.
