I have a 98 dodge caravan the speedometer is way off I will be going the speed limit 70mph but my gauge will say I'm doing like 95mph. My gas gauge when it gets like on the 1/4 mark I need to fill up the van because its empty. What could be causing these things?

I had the same issue with my dodge caravan and after several attempts by the dealer to fix it, it turned out to be a broken wire. They replaced the relay and it would work for a while and then go blank again. Have the wires checked thoroughly.

you will need to check the fuel float for a leak or its got a bad connection on the sending unit for the gauge

The buzzing sound is from the torque convertor lock up solenoid,there is a fuse for this under the hood to verify thats the problem from the buzzing,next where did you get the vss,if it's not oem from a dealer than I would think it's the problem also using a obii scan tool check and clear any codes,so as far as not starting is this from a dead battery or other issue I would unhook the vss and see if it can start.

These vehicles seem to have a problematic short, my grandfather has the same vehicle with the same problem, i found the short under the carpet on the driver side of the vehicle, under the gas pedal, sometimes wires can crack and break.

Make sure you have installed the battery correctly red cable on the (+) and black cable on the (-) side sounds like it may be reversed this wold cause instant battery drain.
