Two problems related to underhood wiring have been reported for the 1997 Chevrolet Astro. The most recently reported issues are listed below.
Was driving and the engine started to miss,and would not pull it's self down the hwy. Then engine stalled, and would not restart. Its was towed to a local chevy dealer,which is 350 miles from my house. Where the problem was determined. The electrical systam was contaminated with fuel. The mechanic poured raw gas from ecm. Apparently fuel is being pumped through the wires that fire the injector to the ecm. The dealer don johnson motors of rice lake ws, had never seen anything like this before. My local chevy dealer sheppard Chevrolet of lake bluff IL has had another 4. 3 in a truck do the same thing. Gm warrented that. But I'm over my standard warrenty and the best they say they can do is 50/50 on the cost,which I think is unfair. They should cover this, as far as im concered this is a safety issue. One spark while I was driving and it could have caught on fire. Don johnson motors had contacted gm technocial assist. When the problem was determined and asked for help. Gm says they have found this problem before but wouldnt give specifics. In reviewing other complaints on the NHTSA web page, others have had injector problems with these vans, but their descriptions are incomplete.
