Re: No Dash Lights No Crank
Probably bad terminals, assuming the batteries are good and the alternator is putting out a charge (note... bad batteries can still hold a surface charge showing good voltage but discharge immediately with a load). Basically, the van isn't getting enough voltage to turn on the PCM, and that's why the check engine light isn't on. I wouldn't keep driving it as-is until you figure it out, because it can cook the FICM in no time.
