my 240 wagon for the second time in the last two weeks won't start up. The last time I filled the tank the night before and as i was driving that night had some electrical difficulties (when i used my turn signals the radio would cut out)then the next night when i tried to start it it wouln't and the same for a couple of days...finally one day it started up. A day or so i filled the tank again, and then last night noticed my headlights dimming, and gas and temp meters dropped down like there was no power and then came back on... and today the car wouldn't start again. any ideas. the first time i tried putting dry gas in, but it wasn't until two days later the car started. any help you could offer would be great. last time it happened on the holiday weekend so it was no big deal, now i really need to get around. thanks.
