Thread: GP starts right up then dies.

Your battery, while small, is not the cause of this issue.

My 2004 does this. There is a valve in the fuel line that keeps fuel from draining back into the tank after you shut it off. That valve is stuck open, so when you start the car, the line pressure is not high enough because the pump has not "primed" yet.

Mine has been like this for a year, its just a nuisance thing. Try this, turn off the radio, and make sure everything is quiet, turn your key to on, you should hear the fuel pump cycle, do it a second time and listen for the sound to get lower in pitch, this is your pump unable to push more fuel because the line is now fully pressurized. Start the car and it should stay running.

This has never given me any trouble while driving, just when starting after the car has sat for a while. It also helps if the car is parked facing down hill.

At 115, you are due for plugs and wires "by the book", but as long as it idles smoothly and no misfires under heavy load, i wouldnt worry too much, you could gain a few MPGs depending on how bad the plugs are.

Don't quote me, but I believe the valve is part of the fuel pump assembly, as is the filter. I have had people try to tell me that cleaning the TB will fix it, it hasn't. I had a shop try to tell me that the pump itself had failed, to which I replied "how did i drive it here then?".

Fuel pump and labor for this car is pretty pricey, so I just deal with it. Its not really a big deal.

I was going to say first thing was clean throttle body. But since you did that, maintenance. Replace the wires and plugs. Just go with stock plugs and stock wires. Try to find a house brand stock wires that have a lifetime warranty. If you have never done anything to the transmission, now would be a very good time to drop the filter, and drain fluids. Put in new filter and fluids Do that before you have any problems with your transmission.

As for the fuel pump/fuel filter... it honestly depends. Some '05s had in line fuel filters... other were in the pump assembly (non-serviceable that is supposed to last the life of the pump). Try putting some fuel injector cleaner in your fuel.

Like Chad said, turn the car to KEY ON... non running and you should here the fuel pump whining then turn off.
