Cured: High Speed, Random Hesitation and Slow Starting

Post by algopin »

For two or more years my AWD, 2002 Astro was plagued by an engine hesitation at speeds in excess of 50mph. The hesitation was not continuous; it would buck once or twice and might not reoccur for seconds or minutes or hours. It was unpredictable.
I also found that starting, while certain, took several attempts, which I took to be normal.
I tried to eliminate the hesitation with a new fuel filter, a full tune up, and the addition of fuel injector cleaners. Nothing worked. I considered replacing the distributor as has been suggested here and elsewhere on the Web; I'm glad I followed the advice of Gerald at Overland Vans and didn't.
Leaving for a thirty day road trip my fuel pump failed completely. I had it and the fuel filter replaced and continued on with a round trip from So. California to Jasper, Canada and back.
Both problems vanished. In over three thousand miles of travel the engine didn't hesitate once. Now it starts instantly and w/o the need to "give it the gas."
Apparently the fuel pump was in a failure mode for years. Who would figure...?

I get chills without my van.

Damn Fuel pumps!!

Now it's fixed and you don't have to have those thoughts about whether or not you are going to keep the van... (not that I think those thoughts ever crossed your mind)
