    Suggest checking to see if the fuel level sensor is working. At the fuel filler (have to remove the cap and rubber boot to get access to the wiring); un-mate the connector and use your voltmeter to measure the voltage across the gauge side of the connector. Should be +12V. Then measure the resistance across the fuel sensor side...should be between 90 and 10 ohms, depending upon fuel level. If resistance is higher, then you have an open which is why the gauge is always showing full.

    If the problem is the fuel sensor, pull it out of the tank and probably just needs a cleaning, hopefully no broken wires.

    Let us know.

    Was it reading full all the time before you got behind the dash?

    Default WAS fine untill....

    Errrrrr, no working perfectly ,,untill I got my mitts on it , Its just frozen at FULL now , I did the entire interior ,so carpet ,seats ,console etc out .
    Do you think I could have broke a wire along the way ??
    Just picked up a new voltmeter ,going to test after the HURRICANE ,,,unless i get swept away.

    Going to tell my wife that it wasnt me but the Hurricane that caused the gauge to go dead anyways !!!

    Yep...you broke....I mean Irene broke a wire. An open will show FULL.

    Time to pull the console back out and check the wiring between gauges and the fuel tank.

    Normally it's the crappy plastic circuitboard. Mine looks like has "survived" two huricanes, it works but I don't know how and for how long.
