Looks like you're doing a "cover all bases" play. An act of love, surely.

1. Fuel pump relay
2. Ignition Power Stage
3. CPS
4. Tank Pump
5. Fuse and terminal connections.

I can think of one other weak point in the path taken by 12-volt power to the engine management system. At least, one I've had trouble with in a '91 and believe still is present in the '92 harness. Behind the glove box:







Overheated connections. Check it out. My "trouble" was not confirmed, only seen as a suspect, so I just bypassed the harness connector to be rid of the possibility. The red wires are sharing the current to the EFI system most likely because one single wire would certainly be too much for the capability of this connector.

So far, I've not ever had a problem with an ignition coil, another item that can be trouble in the heat, as Chuck mentioned. But remember, my experience is with a small family fleet, much like yours, not enough to really evaluate likelihood.
