Weird car problem.......
 

My Astrovan has a 27 gallon gas tank and the fuel pump is in the gas tank. As long as the tank is nearly full, it runs great. But when it gets down around 1/2 tank it misses and sputters and will even stop sometimes. But if I wait awhile, it will start and run again but will continue the problem every few miles. Fill it up and it runs great again. Any ideas?

Ping pong ball(or other floating object) in the gas tank? I've heard that ppl do this, but I've never verified that it actually works.

keep the gas tank full?

Sounds like something is floating around in the tank restricting the fuel flow.

check the Injectors as well, They may be clogged

I had a similar problem in my last car (accord)

I just kept the tank full and sold the b!tch.

And they become magically unclogged when the tank is full? Stupid n00bs!! :cuss:

Astrovans suck.

There used to be some dumbass on this board by the name of Skip Towne. Every time somebody assaulted a Chevy product, he'd come around saying that he had 300,0000,0000 miles on his Astrovan.

He's probably broke down on the side of the road somewhere.

Injectors don't stop working then magically start to work, this ain't Disney, OK.

Skip, have it checked for a line restriction. Either at the tank or a weak hose ( the small rubber hoses in certain places around connections ) that is collapsing.

Fine Change the Fuel Filters and Call me in the Morning



|Done

Sometimes fuel filters will get so full that they will let fuel thro, but after running a while, they stop. As the engine is idle, the settements settle in the filter causing it to run again, just like at the line pick up point.

Something like that could be happening but the gas line is metal all the way from the tank to the engine. I've never seen anything like this before.

Reboot the damn thing!

OK, I went out and kicked it in the ass. It's still acting up.

As with most GM products, the fuel pump is going to be problematic.
