I think maybe the person might have been referring to setting the timing once the head or cams have been removed. That would not be controlled by a computer. You first have to set the crankshaft marks on TDC, which consists of a groove on the bottom pulley being aligned with the timing tab. Both of which are located on the passenger side of the car. Depending on which engine that you may have(there are 3 possibilites from what I have seen) you need to align the intake and exhaust cam marks with the crankshaft also. Being careful to tighten the caps on the intake and exhaust cams to the cylinder head. .
All timing gears. You have to disassemble the entire front of the truck and engine to access.
Need to replace the electronic timing controll module. It is mounted over by the left valve cover, But bolted on the intake.

Timing for 1990 1500 with 4.3
Yes, not a problem. Any unfit components swap it from your old engine.
Ther are three different engine configurations used on the 1990 prizm. Check a repair manual such as Haynes. If you plan on keeping the car for a long time a manual would be a good investment.
On the engine family .. LTK 3.0 T5 FCC1 there is no PVC valve on 1990 Mazda MPV
