Car started jumping but had 1/2 tank and battery light came on.

put jumper cables to the car like if you are going to jump start the car and then you might be able to open the door to the gas tank.

Likely, your battery is now history. Sorry . .

Possibly a fuel supply issue. Will require a fuel pressure tester. Could be in tank pump or a bad fuel pump relay. In a quiet environment, turn key on (not start position ) and listen if you can hear the guel pump run for 1 or 2 seconds.

I'm not completely understanding what your problem is. You say it shuts off while driving.. You mean the gas light or the engine? Then you said "can turn on by jump start after one hour".. Do you mean you have to jump start the engine and wait one hour before it will start? If that's correct, have you had the battery tested to make sure it's not bad? If your battery is not receiving the charge from the alternator, your cables or battery terminals may be corroded and preventing the current flow from reaching the battery. Take a volt meter and do a voltage check while it's running to make sure you have more than a 13 volt output to the battery.

check fuel filter and make sure its not clogging up, make sure the engine is getting fuel, have someone go under the car where the fuel tank is and have them listen when you turn the key to on to see if there is any sound coming from in the fuel tank, if not, then you may have burnt out the fuel pump. Fuel pumps are Great for randomly going out at a moments notice. those GM v6 engines dont jump time easily so it more than likely wont be that.

Fill up your gas tank and ad a bottle of Lucas gas treatment/lube to the tank, be sure it's the treatment in a little clear bottle and not injector cleaner. After you've added the gas and treatment drive the car, with the head, driving lights, radio, heater, etc. all turned off. It may take ten miles or more but the check engine should go off and car will run normal. NOTE: Never jump start your car or use it to jump someone else's without referring to your owners Manuel.

A week ago, on my Lexus ES 300 (2001), "Check Engine" and "Trac Off" lights came on. This coincided with me filling the gas tank to the brim to round the dollar to be paid. I cleaned the gas tank cap and the tank opening. However, both lights persisted. On the same day, when I turned on the car again, there was a hesitance, a stuttering to come on. Both "Check Engine" and "Trac Off" lights were still on.

The next day, the car wouldn't come on at all. It sounded as the battery was dead. I couldn't even jump start the car. So, I got a new battery from Costco ($59) and put it in. It took 15-20 seconds of cranking to get the car started. Once it was started, the engine sounded fine and the RPM normal. The "Check Engine" light was off. However, the "Trac Off" was still on. I cleaned the gas tank cap one more time.

The next morning, when I turned the car on, there was no problems. It came on instantly as it used to be, didn't have any warning lights, and drove smoothly.

have the alternator checked if that is not it a ground wire loose to the battery or ecm loose connection some where

Sounds like a similar problem I had. I had a bad battery. Jumping the car and charger did not help. All instruments work as I am guessing the battery had enough juice to light those but not enough to start car. Either bad battery or alternator. I changed out the battery and everything was fine. If you have an aftermarket stereo or amp, make sure they are setup right. The amp may be drawing power even if radio and car is off which may attribute to low start power (including above suggestions).

If its a Carburator car then

1.) press the the axcellerator straight down to the board
2.) tumble a few times.. and it should start.

other possiblities besides a flooded cab is

1.) drugs from the fuel tank clogged up the lines or the carburator
thiss will happen when its running low and if the tank is rusted inside.. very hard to detect without removing the tank..

2.) the fuel pump could be clogged up as well..

The clicking sound you might be hearing could possibly be the starter.. It may not have enough power to start. Check your battery to ensure its good. if the battery is dead you may need to get it charged or get a jumper cable and a jump. but for the battery to run dry means that the alternator isnt functioning propperly. once the car is started, remove the + battery pole while the car is idling and see if it stalls or cuts off. if it does get the alternator checked... Personally i'm betting its the battery.
