No Crank No start No click lights and radio work
03 Dodge Caravan has intermittent
cranking. Replaced the starter and
relays and will crank and run for a few
hours then randomly dies and won’t
swap the equal value fuses around to check for a flakey fuse in the power control center under the hood and then at the driver's feet, then check the ASD relay and the roll-over switch and wiring that operate the ASD relay before probing for a ground problem and other wiring problems. my personal guess is a bad ground at the PCM, but the odds are only best not high and its a PITA to check compared to the other choices.
