Astro Van that sets more than 12 hours will not start until ambient temperature inside car gets hot. Shop replaced plugs, wires, cap, rotor, pvc, fuel filter, and induction system cleaning and fuel injector service. Tested fuel pump ok.
Looks like the battery cables (both ends) were not serviced Remove/clean and replace wrench tight.
If in fact, the temp inside does have a bearing on the fault, I would suspect a possible ignition problem.
