Hello gang! New guy here, but looks to be an awesome site. I hope that someone here can help me out (and I the same for someone else!) Anyway, here goes...

I have a 1992 Ford Ranger XLT l4 2WD. Truck has run great, up until the last ~1 year or so. It has been having issues starting. At times, it will start intermittently, and other, it will just turn-over and over and over, without starting. Now, we have had pretty much all ignition system components replaced in the last 1-2 years. This is why I am at a loss.

Today, we tried to start her up. The truck just turned-over and would not fire-up. We sprayed some ether, and she would start VERY briefly (like 1-2 secs), and then quit. I decided to run a self-diagnostic, and got the following OBD1 Codes...

543 - Fuel pump monitor circuit shows no power (power/fuel pump circuits.)

224 - Failure in ignition coil primary circuit (ignition systems.)

223 - Dual plug (DPI), SPOUT or IDM circuit fault. (Ignition systems.)

222 - IDM open or high or right coil pack failure. (Ignition systems.)

218 - IDM signal open or high or left coil pack failure. (Ignition systems.)

211 - Ignition PIP signal was erratic or missing. (Ignition systems.)

157 - Mass air flow signal is/was low or grounded. (MAF.)

With all this said, I did a little perusing on the interwebz, and came up with this video on YT,

It is a '95 Ranger, and he found that a wire was loose on the fuse box for the fuel-pump relay. Is this something that could occur with my '92?

Any info that you all could give would be much help! Thanks again!
