Have a 90 Buick LeSabre that seems to kill fuel pumps every year for the last 4 years. It has been replaced each time at differing dealers and with new wiring harnesses. What could cause this?

How full do you keep your fuel tank ? If you repeatedly let the fuel level low ,this will cause premature failure ! Need's to stay around 1/2 tank or fuller , keeps fuel pump lubricated . So if you run your vehicle with a 1/4 tank or less all the time , this will cause fuel pump problems .Could have a resistance problem in the electrical circuit ! Does the connector at the pump look burnt when changed ?

My 98 windstar hesitates when i go over 40 mph it almost comes to a stop than goes again like a jerking motion had it in the shop an they couldnt find anything wrong cause it doesnt do it all the tim

Do a flow test. Disconnect fuel line from filter to carb, point line at empty container and briefly run the engine. The pump should produce at least a cupful of fuel in a few seconds.

My 2500 chey silverodo starts hardfor the first 10

Hi, if it's a diesel engine, they all have to sit for some seconds because of the glow plugs. Some diesel don't send power to the starter until the glow plugs run for the pre-determined amount of time. There are many things that could be causing this. Fuel filter, clogged injectors, fuel pump going bad or bad connection to fuel pump. Try checking out for this things..
Take care

Gas filter location on a 2005 chev. 2500hd pick up it is not along frame rail like on 98-2001 models

As of 2004, fuel filters are in the fuel tank as part of the fuel pump.They have a life expectancy of around 150,000 miles as to that is when the fuel pump starts to fail. You can get more life out of the fuel pump if you keep the gas tank over 1/4 at a time, the more the better since it's the gas that keeps the fuel pump cooled. The fuel pump has a double filter system, there is a filter screen on the pump unit housing about 3/4 up so all the larger dirty stays at the bottom of the gas tank, and then another finer screen on the pump pick up tube it self in the housing. With the double filter system, it has a much longer life and will out last the pump it self. Good luck and hope this helps and best thing you can do as mentioned is keep gas above 1/4 and add fuel injector cleaner once a month to your gs tank or every time your service the truck. "oil and filter changed"
