[98wsnj]

Hello , it has been some time since I had to ask for your help again and I am hoping that one of the experts here can guide us in the right direction.
We own a 98 WS 6 cyl. had the usual problems like everyone. I was in the hospital and was discharged yesterday, my wife picked me up in our 98 WS. It started and ran good for her all day. When we got home she let me out and shut the van off and when she went back outside to start the van and put it in the garage WELL it only was able to crank but not start at all. The battery is new ( less then 6 months) and the light, radio etc. work. About 2 years ago we had the same problem and I diconnected the battery to reset the computer module and it started right up. This time I went outside this morning and tried to start it and it still would only crank but would not start. I diconnected the battery and waited 1 hour and the same thing will not start. We just reserved a rental for Tuesday (a extra expense that is coming at a bad time). Can anyone give me some clues as what to check for real fast, if I can get it started my wife can drive it to the repair garage.
Thank you in advance for any help.
