Two problems related to engine shut off without warning have been reported for the 1999 Plymouth Voyager. The most recently reported issues are listed below.
The van will be going along and just shut down. No advance warning. Sometimes it will start after setting for 30 minutes, sometimes it has to sit for 24 hours, sometimes for 2-3 days. The van has been towed to the dealership 3 times and each time the van starts right up and runs with no problems. Then a week or so later it starts all over again. Dealership cannot find the problem. The van is a hazard because it will stop in traffic and you don't know how long it will take to start.
Three times I was driving about 70 miles an hour and my car completely shut down without warning. The first time I took it back to the dealer and the computer codes said there was loose relay wire to the fuel pump. About 1 week later it happened again at 70 miles an hour on the freeway and it quit on me again. I used another vehicle for work and the 2nd day after the 2nd incident I took it to the dealer. They kept it for 3 days and they stated no computer codes came up. It happened again for the 3rd time on 9-30-99 and I drove straight to dealership. They are closed for 4/5 days for exterminating. I told the guy this is the 3rd time it happened. Sorry but everything is closed until next Tuesday. I only drive in the fast lane or the complete right lane in fear this will happen again. When it shuts off I have to sit there for about 5 min, pump the gas pedal and then it starts. With or without the air conditioner on it does it. It constantly feels like it is going to die out on me. It is scary driving out here on the freeways with a semi-truck on your back and a car stalls out on you. I told them that but they say they can't.
