    unrelated problems but I thought id just mention everything a once. so starting out I changed my fuel sending unit about 5 months ago and the gauge started acting funny a month later (saying I have 3/4 tank when I only have about 2 or 3 gallons left) then a few weeks later just completely stopped working (says full tank when the car is started then moments later says tank is completely empty for the rest of the drive no matter how much fuel I actually have). I checked the connections at the cannister and everything seemed fine and checked the connector with the key in the on position and got 4 volts? is it supposed to be this low if not what do I look for?

    for the second issue I changed my lifters last week and had my battery disconnected from the ground for the entire install. took me the whole weekend as I was busy with other stuff but everything runs great except I cant turn the radio back on? its an aftermarket pioneer radio btw only maybe 2 years old. I've checked fuses, unplugged the radio and plugged it back in and checked the fuse in the actual radio.

    also on a side note I never did figure out why my heated seats don't work? the elements in the seat are fine connectors are solid and I've tested multiple hvac control units and none of them made my heated seats work. also checked the fuse.

    these cars are an electrical mess lol

    Did you use the old fuel level sensor? If so, it may have given up after the move.

    no its a new sensor from oriellys paid like $34 bucks for it came with the float arm dial gauge thing the float arm moves on and the wire harness. also the radio issue has been solved just needed to pull out the fuse and leave it out for an hour to let the radio completely drain all its power somehow it can store power for a bit lol
