Car Forum / Chevrolet / Chevrolet Trucks / December 2004Mysterious problem solved
I'm posting this to get it into the usenet archives. Hopefully, this saves someone else some headaches. :-) I have a 96 half ton chevy express van. The problem was that it would occasionally die leaving us stranded. The problem acted like a bad fuel pump. After towing home, it would mysteriously start the next day and run for a while longer, maybe a month. We towed it to the mechanic hoping it would break for him. Sure enough, after towing there one night, it started for the mechanic just fine the next day. After several days of perfect operation, I stopped back by to pick it up. I started the van and it died. I didn't even get out of the parking space. The mechanic was still there and ran out with some test equipment. It turned out to be a bad fuel pump. It would quit working whenever the ambient temperature would drop below maybe 15 degrees. I've never seen a fuel pump do this before. I always thought that once they died, they were dead for good. A new fuel pump fixed the problem. brian > I'm posting this to get it into the usenet archives.

It would be nice if everyone did this, many here do, more than a few don't. Whitelightning > I'm posting this to get it into the usenet archives.

Around 75000 miles it would start fine after sitting over night but if I shut it off within 5 minutes of starting I couldn't restart until an hour or so passed. If I didn't shut it off the engine would run fine. Ambient temperature wasn't a factor. The fuel pump was the culprit. In fact I could duplicate it's behavior on the bench. I had almost the same problem with an old ranger in the late spring. When the temperature climbed higher than 20 °C the truck would die out on me. No one could figure out the problem. After much diagnosing it turned out that the power wire leading to the pump itself was proken and when heated up it would separate cuasing the truck to stall. >I'm posting this to get it into the usenet archives.

My friend and replace the motor in the truck along with that came things like new fuel lines. This made my trouble shooting really fun. I could drive the truck around town and then all of the sudden it would start acting like it was out of gas. I would have somebody come pick me up after spending time trying to get it started. I'd come back the next day and it would be fine. The truck did this for about a month until I finally took it to a shop to have them look at it. turned out to be that when the body shifted just right it was pinching off the fuel line. > I'm posting this to get it into the usenet archives.
