May have been mentioned before but some cars are equipped with low oil pressure cutoff that interrupts the ignition circuit if oil pressure falls below a certain level. The vehicle control module bypasses this in the start mode but only for a very short period. If when trying to start the oil pressure does not come up to a predetermined level the ignition circuit is interrupted. I think the suggestion for a crankcase heater is right on.
