Using The Engine Block Heater (If Equipped) - Ford 1998 Ranger Owner's Manual

Starting
2. If the engine does not start within five seconds, wait ten seconds and
try again.
3. If the engine does not start in two attempts or if the temperature is
below -12°C (10°F), depress the accelerator and start the engine while
holding the accelerator down. Release the accelerator when the engine
starts.
4. After idling for a few seconds, apply the brake and release the parking
brake.

Using the engine block heater (if equipped)

An engine block heater warms the engine coolant, which improves
starting, warms up the engine faster and allows the heater-defroster
system to respond quickly. Use of an engine block heater is strongly
recommended if you live in a region where temperatures reach -23°C
(-10°F) or below. Your engine block heater also comes with a battery
warmer. The battery warmer wraps around the battery and keeps the
battery warm when the engine block heater is plugged in.
For best results, plug the heater in at least three hours before starting
the vehicle. Using the heater for longer than three hours will not harm
the engine, so the heater can be plugged in the night before starting the
vehicle.
To prevent electrical shock, do not use your heater with
ungrounded electrical systems or two-pronged (cheater)
adapters.
