shortly after i got my step van and made a few simple modifications it started making this beep beep beep sound than has never stopped. Every once in a while i notice it is not happening, but otherwise i could make a 14 hour drive and i goes on and on.
i have checked ALL the fluids; it is not overheating, and the "water in fuel" sensor is not lite up on the dash. I tried disconnecting the positive terminals on the batteries and that did not stop it.
Any advice on how to figure out what it is trying to tell me, and how to make it stop? It does not seem like anything is wrong.
thanks,
Paul
