I have the best possible type of problem - a reproducible error. Here’s the data:
I have a 1994 Toyota Camry with 262K on the car, about 180K on a repplacement OEM Toyota engine. I also drive a motorcycle every day, so the Camry sits for weeks at a time without use. I think prior to the problem surfacing, it may have been more than a month since it was driven anywhere. It’s still a great car, but the bike is more fun.
It was cold and rainy last week, so I thought it would be a good day to take the Camry to work. As she always does, she started right up without hesitation. I left the house, and got about 4 miles before pulling into a gas station to check the tire pressure. As I entered the station parking lot, the car just shut off. Dead. I thought maybe it had just idled too low, and I tried restarting (several times). No luck. Pushed it into a parking space and walked home. Took the day off. Later that evening, we took the other car over to try and tow it the short distance home, but it started right up again, and I was able to drive it home without incident.
So this morning, I think maybe that was a fluke and tried driving it to work again. I made it about the same distance, and it died again. I had a fully charged laptop with me, so I just sat there and worked for about an hour, and sure enough, she started right up again. I headed home, but she died again, just about 0.1 mile from home. Did some more work; and 45 minutes later, I started her up and went the last 0.1.
So clearly there is a finite and predictable distance/time it will run. The electrical system seems strong, and my suspicions are strongly on the fuel system.
What could be causing this? Inasmuch as the car sits for long periods, I’ve considered condensation in the tank, but would that manifest itself in this way?
