#45 of 108 Re: Chevy 2002 express van with 5.7 liter engine will not start [van3500]

Monday afternoon: At the Chevy dealer's I talked to the service writer, he asked a mechanic to talk to me, his thoughts, loose wire or bad connector. Especially after the engine stopped there were no codes. The event causing the problem happened and simulated the key being turned off. He recommended checking each wire, looking for a loose connection.
I talked to a friend that works at a truck garage. When I mentioned plugging the OBDII tester in and the warning / status lights came on he said I had a bad ground. I found a loose ground wire at the thermostat housing, Tightened the ground and the van is running fine. I will monitor for a few days until my confidence in the van returns.
I hope this helps others.

I have a 2002 Chevy Express 3500 with 56,000 miles. Last December out of the blue it would not start after a trip to the store. After many tries we got it to barely start and it sputtered and clanked the entire way home. The dealer couldn't get to it for a few days and we were able to drive it but the engine would only turn over when it was cold. Once it got heated up you had to wait a couple hours before starting it again. The dealer claimed it was the starter and battery and strangely enough after those were replaced it seemed to run fine.
Fast forward to last month. We purchased a minivan and have only been driving the Express maybe once a week and only into town and back (3 miles maybe). It hasn't had a full tank of gas since the beginning of October and has been sitting on a quarter tank for about 6 weeks now.
Today I went to start it and it gave me a bit of trouble but once it got started it ran fine and I figured it was due to the low amount of gas and the fact that it just sits around so much. I made it to the store (9 miles away) just fine but when I got back out it wouldn't start for anything. After a million tries and having it barely catch just to stall it stayed running but was clanking and could barely go over 10 miles an hour. I made it to a gas station and after adding $20 worth of gas it started better but still kept acting like it wanting to stall. There was also a banging sound coming from the exhast.
I called my father-in-law and he started it and let it run for awhile. He managed to drive it home just fine, he said at first it wanted to stall but then ran perfectly after about a mile or so. Now the SES light is on which is the first time I've ever seen it on this van.
Any thoughts/ideas? I'm not sure how it ran for nearly a year before acting up again.

I started the van up that night and it started just fine. We let it sit for two days while we were out of town and when we got home it started just fine. I drove it into town and back yesterday and NO problems whatsoever. I don't get it, I think the van is just possessed or something. The SES light was a misfire (P0300) and did not come back on once it was reset.

Hi igsg8tor - did you resolve this problem? I recently purchased an 06 Savana with 30K miles that seems to be experiencing this same problem. Any help would be appreciated. Thanks.

Where able to fix this problem? I'm looking at buying a 2002 Chevy Explorer van with the same engine as your's and I thought it might help me to know what your problem was and how to fix it. Let me know please.

From Van3500, my problem was traced to a loose ground wire for the on-board computer. The ground connection was at the thermostat housing. I had worked on the engine replacing the intake manifold gaskets as I had a coolant leak.
The coolant leak was slow with no visible signs. I purchased an oil analysis kit from NAPA and the report indicated high coolant levels and contamination of the oil.

Just an update for information that may be useful. I replaced the fuel pump myself with a new e-Bay pump ($100) and it was an easy job. The hardest part would have been the long fuel-tank hanger-strap bolts, but I used an air-impact to run them out and back in when I was done. After I was done, the van still wouldn't start, and to make things worse, the old fuel pump ran on the bench with 12v.
Having lost faith in my own ability and after reading about the hundreds of things that could be wrong, I just let the van sit and waited until I had $1000's to take it to a repair shop. Been down that road before. When they know you tried and failed to fix it yourself, you sense the red dot on your forehead.
A year-and-a-half later, armed with lots of bend-over $ and a wife who wanted her car back, I finally had the van towed to the nearest repair shop. Happy ending! My fuel pump job was good but somehow I managed to blow one of the ecm fuses after I put it in. Since I had carefully checked all the fuses before, I didn't bother to check them again.
