No power to my ignition switch on my 1990 Pace Arrow

Most likely the ignition switch or the rod in the steering column is sticking and keeping the switch engaged, possibly the ignition lock cylinder is sticky too. Easy to get lock cylinder out with a small punch that depresses a pin when the lock cylinder is in the run position, look under the steering column by the switch for a hole to poke the punch into and then pull out the lock cylinder.

defintely sounds like fuse or relay. also could be relay for your headlights thats runs to the ignition switch as well. trace your wires from ignition switch out through the firewall and see where they go. may need to have second person help. Wherever the wires go is prob your problem. Most likely a relay. also check for any hot wires loose touching thats shortening the circuits.

In this truck the problem you have is many times caused by a defective Ignition Stater Switch, this switch is what is operated by the key via a long rod, the switch is located at the bottom top of the steering column, it sits on two studs and is held in place by two nuts, the switch goes over the end of the rod, the rod moves the switch contacts to provide power to the truck electrical system when you turn the key. The problem with these switches it that they come apart at the metal tabs that hold the two halves together, then the contacts don't mate up and no power, Ford recalled many of the Trucks that used this design of switch for this reason (you can call a Ford dealer to determine whether you qualify for the recall by the VIN of your truck). The switch is easy to replace and very cheap to buy from any auto parts store.
To replace the switch remove the lower dash panels below the steering column tube, remove the 2 15mm nuts on studs that hod the column up, and slowly drop the column part way, the remove the shift indicator cable clip from the steering column tube cover then drop the column down lay it on the seat then you can easily access the switch, here is a picture of the switch and how it separates to cause the power loss, this is shown in the right hand side of the image below..

check the ignition starter switch 1st, it is the main switch that the ignition key truns on to power up the electrical system, it is on the top of the steering column tube near the bottom, it is driven by a rod from the ign key cylinder

replace the ignition switch
The ignition switch is usually mounted to the steering column and is operated by a linkage rod.
NOTE On column-mounted ignition switches, don't confuse the switch with the lock cylinder and keys. The ignition switch is not normally visible. On some vehicles, the steering column support has to be removed and the column lowered to find the ignition switch. On others, the switch is accessible under the dash.
The ignition switch is operated by the key switch. Courtesy of Ford Motor Company. To replace the switch:

• Remove the ignition switch wiring harness.
• Unbolt it from its position.
• Bolt the new switch into position.
• Attach the witing harness.

Ignition switch installation-1984-90 models

1. Disconnect the negative battery cable.
   
2. Remove the steering column cover.
   
3. If equipped with automatic transaxle, position the gear selector into DRIVE and disconnect the indicator cable.
   
4. Remove the lower panel reinforcement.
   
5. Drop the steering column for switch replacement.
   
6. Disengage the wiring connector from the ignition switch.
   
7. Position the ignition lock cylinder into the LOCK position.
   
8. Tape the ignition switch rod to the steering column to prevent the rod from falling out of the lock cylinder assembly.
   
9. Remove the screws attaching the ignition switch to the column jacket.
   
10. Remove the ignition switch by rotating the switch 90 degrees and pulling up to disengage from the rod.
    

To install:

1. Rotate the switch 90° and push down to engage the rod.
   
2. Install the screws to the ignition switch mounting plate but do not tighten.
   
3. Remove the tape holding the rod to the column.
   
4. Adjust the switch by pushing up on the switch to take up rod system slack. This must be done with the key cylinder in the LOCK position and the key removed.
   
5. Tighten the screws attaching the switch to the column.
   
6. Connect the wiring connector to the ignition switch.
   
7. Install the steering column.
   
8. Install the steering column cover.
   
9. Connect the negative battery cable.
   

1. Disconnect battery ground cable.
2. Place lock cylinder in the Run position.
3. Remove steering wheel.
4. Remove turn signal switch. It is not necessary to completely remove the turn signal switch from the column. Pull switch rearward enough to slip it over the end of the shaft. Do not pull the harness out of the column.
5. Remove attaching screw and lock cylinder set. Do not drop the screw into the column.
6. To install, align cylinder key with keyway in housing, as shown in Fig. 1. Push the lock completely inward, install attaching screw and torque to 40 inch lbs., on standard columns, or 22 inch lbs., on tilt columns.

Remove panel under steering wheel. Put key in cylinder and turn back to accessory position. Looking under lower part of steering column locate a small pin under the key cylinder. While depressing the pin turn the key backwards and pull the entire cylinder with key out of column. Good luck.

Removal & Installation
Without Air Bag
See Figures 1, 2, 3 and 4

1. Remove the turn signal switch.
2. Insert the key in the lock cylinder and turn it to the ON position.

Fig. 1: Using a pair of needle nose pliers, remove the key warning buzzer switch and contacts from the steering column

1. Remove the key warning buzzer switch and contacts AS AN ASSEMBLY using needle-nosed pliers, or a paper clip with a 90° bend.

Fig. 2: Lock cylinder retaining screwSome steering columns may have a retaining screw holding the lock cylinder in the column. When servicing this type, simply remove the retaining screw and remove the lock cylinder.
Fig. 3: Using a small thin bladed tool, press in the ignition lock clinder retaining tab ... Fig. 4: ... then pull out the lock cylinder from the steering column

1. With the ignition switch still in the ON position, insert a thin screwdriver into the slot adjacent to the switch attaching screw boss (right-hand slot). Depress the spring latch located at the bottom of the slot to release the lock cylinder.
2. Remove the lock cylinder.

To install:

1. To install the lock cylinder, turn the key to the LOCK position. Insert the lock cylinder in to the housing far enough to contact the drive tang. Force it inward and move the ignition switch actuator rod up and down to align the components. When the components align, the cylinder will move inward and the spring-loaded retainer will snap into place locking the lock cylinder in the housing.

If the lock cylinder is retained by a screw, tighten the screw to 40 inch lbs. (5 Nm).

1. Install the key warning buzzer switch.
2. Follow the ignition switch installation procedures to adjust the ignition switch.
3. Install the turn signal switch.
