Weird car problem....... - Page 2

**Skip Towne** · 02-28-2006, 01:53 PM

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?

Do you use any fuel additives in it ? I know in our big trucks, at times drivers do not get all of the silver seal off of the additives and it gets in the tank, restricting the pick up lines.

I'm seeing a new fuel pump in your future. It's probably weak, and due to some kind of law of physics the added pressure on the bottom of the tank when it's full is assisting it in pumping the fuel somehow. Does that make any sense?

There may be a fuel filter that looks like an oil filter somewhere near the engine if there are no in-line filters. My friend's girlfriend has a subaru with a filter like that. I hadn't ever seen anything like it before. All the GMs I have had the fuel filters are in the lines. I hate the fuel system, it is always messy and dangerous.

Yep. It is probably the fuel pump. Test it by checking the fuel pressure.

It could be possible that your fuel pump is getting weak. Its possible that there is some crud(rust) floating, and when the tank is half full, it is blocking the line.

Very possible. I've had fuel pumps quit three different ways so far. This could be way #4.

Yeah Since you had changed the Fuel Filters then its time for a new pump.

I reccomend a Holly Blue

After careful consideration I've determined that your problem is the fact that you are driving a Chevy Astrovan.

Yeah, if it were your car just getting the little pieces of rice out of the caburetor would fix it.

According to the dog shown below, it's called a Rastrovan.

I reckon a full tank would be mean less slushing, so maybe rust was the right answer

I don't know if anyone has said this already, but since your fuel pump is in your gas tank, the screen over your fuel pump might need to be replaced.

Or this. Might be new fuel pump time.
