ABS & Low Fuel Light

Hello. For the past couple of days my ABS and Fuel Light has been coming on. When this happens, my speedometer, windows and heat does not work. When I put my foot on the gas the van takes off very slow. I looked in the manual and it said to cut the car off and it should reset. This worked at first but now it's back on. Does anyone have any suggestions as to what may be causing this. Oh yeah, another thing that happens along with everything else is, when I cut the lights on I will get the dinging noise that I would get if I had the car off and left the headlights on or if I left the keys in the car. It sounds like it may be something electrical. THIS IS DRIVING ME CRAZY!! PLEASE HELP!!

YOUr profile indicates this is probably about a 1994 transport...
Occurences of tht type are frequent and often traced to failed ground connection, something occurring at base of left A pillar or under driver floor....maybe this
