Van chugs/stutters intermittently at a consistent high speed, fuel gauge vibrates, sometimes (rarely) it turns over and acts like it wants to start but won't. Replaced, fuel pump, fuel filter, ign coil, coil wire but no change.
My 99 GMC savana 1500 was chugging at like 50 60 mph and gas gauge was stuttering ..it turned out to be computer..I had it re flashed by GMC for 150 bucks ..that fixed all...hope this helps

Fuse? Check crank position sensor.

The only thing left in this system is the fuel pressure regulator. You need to check pressure before the regulator and after the regulator if there is the problem then you need to replace it. I hope this helps. Don't forget to rate my answer.

could be a bad fuel pump, or fuel pump relay. they are having problems(a lot) with the ethanol in the gas on GM products.Fuel pumps sales are through the roof at parts house on GM's. Have a pressure check on your fuel system. That is probably it. Add a can of Seafoam to your fuel every 3000 miles to alleviate this problem.
SOURCE: stuttering on acceleration and/or at highway speed
it also could be a plugged catalytic converter. hope this helps
