Just bellow half tank mark, car starts missing, has explosive noises and finally engine dies and will not start until more gas is added.
After the engine died on half tank open the fuel cap and let air in. Sometimes the tank air vents are blocked and as the fuel is drawn out the tank a vacuum is created that is strong enough to override the fuel pump pumping capability.
If this does not help it is the fuel pump not being able to lift fuel out of the tank due to normal wear and tear of the pump or damage to the pipe leading to the pickup point in the tank. Replace the pump and assosiated piping.
Sound like fuel pump problems or clogged fuel filter, replace fuel filter first then check fuel pressure should be 26 - 45 psi for 3.0 engine and 43 psi for a 3.9 engine.
Give use any codes you may have

This sounds like the PCM has taken a turn for the worst. The pcm relay sends power to the fuel relay for 2 seconds to prime the fuel system just before start up.
Then the pcm ungrouds the signal for a prove out.

hi,
if its a 3.8 v6 then check the EGR valve. the egr valve will get a hole in it an cause a huge vacuumn leak, and cause that. untill you take it in you can plug the vacuumn hose that goes to the EGR valve on the intake manifold, fix it soon.

You have two pumps,I guess you know that ,if you already did one. Did you check fuel pressure at the rail and check out the electronic pressure regulator? What codes are coming up and do they stay set?

Hello, Take your car to an Autozone, Oreillys, or Advance autoparts store. Any of them will give you a free scan for the cause of the "check light". You may be able to buy the correct part to fix your car and it may be a simple matter of switching a part on a connector.
The Parts guys will be able to tell you where most of the parts go and what is needed to change them. After the new part is installed you may need to have the onboard computer cleared or you will see the old warning for some time.
If the scan shows nothing, then a fuel sample with a change of the fuel filter would be the next step I would take.
If you have any trouble Code numbers to identify, you can send them here and we will identify them for you.

The Codes you should get will be P1232,P1233,P1235 orP1237 It would seen that the fuel level is not being sensed until you keep the tank fuel & the PCM & other Module think you out of fuel. Sounds like a worn out sending unit. The exhaust has to be lowered,driveshaft remove & fuel tank dropped. I wouldn't pay a dealer for all that,it will cost a fortune. Get quotes from a few local shops
