Yes ANSWER No - a 1998 3.0 L Ford Ranger does not have a distributor which would allow you to adjust the ignition timing - it has a coil pack and the ignition timing is controlled by the PCM ( powertrain control module )
1994 was the last year the Ranger used an ignition control module on the 2.3 and 2.5. The ignition control module was attached to the lower intake manifold.
The PCM relay is relay # 4 in your power distribution box in the engine compartment , also in the PD BOX in location # 6 is a 10 amp mini-fuse for the powertrain control module and in location # 8 is a 30 amp mini-fuse for the PCM relay . Ford recommends disconnecting your battery before servicing fuses/relays in the PD BOX which means your Ranger has to re-learn its idle etc.
In a 1997 Ford Ranger, the wiper control module is located behind the radio compartment. It sits on the left side of the compartment.
