Last week it did the same thing. I turned on my car and the fuel needle didn't move off of empty. When I got to where I was going and finished what I had to do, I cranked up the car and the needle moved back up. Now I am having the same problem again but this time the needle is not coming back up.
According to my info, If pcm detects a problem with sending unit or circuit, the guage will default to empty. If the ipc detects a problem with data circuit from pcm, again defaults to empty.
You could use resistors across sending unit circuits, to see if guage reacts properly, if the guage reacts accordingly, I think the problem is the sending unit in the gas tank. Are there any applicable trouble codes, if there were any it would probably be a communications code. Some of the national brand auto stores will check codes for free.
You can get resisters at several places. I heard radioshack was going bankrupt. I don't know if their stores are still open?
40 ohm resister= empty
250 ohm resister= full
Could be a few thing's, most obviouse not a lot of fuel but I take it you have plenty in your car, sticking fuel guage,faulty connection somewhere, or a dicky guage are some of the causes
It sounds like a problem with the fuel gauge sender unit in the fuel tank which has worn out and gone open circuit and needs replacing. Access to the unit is usually through a removable plate in the floor in the rear of the vehicle. Disconnect the wiring connector and any hoses and then remove the securing screws. Replacement is done by reversing procedure.
