My 1989 Ford Taurus GL 3.0L has been having issues with the fuel gauge lately. Sometimes it reads correctly but most of the time it doesn't. Now twice this week I have had a no-start problem. This morning I went out and cranked it until the battery was low. Put a charger/booster on it and still nothing. I checked for spark and am getting it. I then finished charging the battery. I also checked to see if there was fuel at the Schrader valve, and there wasn't! I added a gallon of gas and still nothing. So I was assuming that it is the fuel pump in the gas tank, that I replaced four years ago. I got some neighbors to help push it into my carport and let it sit for a few hours. I went back out and tried it again, and it started. I then checked for fuel at the Schrader valve again and had some. This is the second time this week this has happened, and I can not afford this to happen again. Should I still be looking at my fuel pump?  |

I would catch it isn the no start condition and unplug the fuel pump and check for current at the plug. If there is current at the fuel pump plug and no start, the pump is probably bad. If there is no current, there is a CCRM (Constant Control Relay Module under the radiator cover that houses the relays. It is an intergral unit and has to be replaced as a unit.

Oh no not that thing again!  I think I found the problem. I have been using the trip meter as a gas gauge. It occassionaly will stick when the 100's number turns. Evidently, I wasn't driving when it stuck again, and it was just low on gas. I like easy fixes. So I guess that leads to, how do I get my gas gauge to read correctly? |

You need to u nplug the wiring connector at the tank and find the wires to sending unit. Turn key on ajd use a jumper wire between the input and signal return to see if the gauge moves full scale. If it moves from empty to full--or full to empty, the sending unit in tank needs replaced. It is attached to the fuel pump module. If gauge does not move full scale, replace the gauge

Is it possible to do this without dropping the tank? I just filled up.

yep. but to change the unit you need to lower the tank. You can just drop the rear of tank and there is enough room to remove it
