let ignition system and alternator be dry, then masure battery voltage.

the wors could happen - water short voltage regulator and overvoltage kills electronics and engine dies

My aero was in so deep ditches too. I had dirt under distributor cap and hight voltage leaks (looked like sparks in dark)...

Try to cap out, clean cap inside, rotor. Check coil for bad insolation, ditr, water, corrozion...

Onese I got in deep puddle and my aero ran till distributor was wet. was towed out. Cleaned distributor and wires, but later changed oil, tranny fluid and rear end lubricant. Got imulsion inside.

All miss problems were ignition ralated.

Do you have a hole in your gas tank? Sounds like you have water in your gas. Also you might have a bare wire in the rear for your lights to blow. Water is a very good conductor of electricity.

Check to see if the vacuum line to the fuel pump regulator blew off when it backfired. That would jam your pressure to the max and make the engine run very rich.

measure fuel pressure. appr. 3 bar at idle, and up to 3.6 bar when engine revs up.

So, I say to the Doc, "It hurts when I do that." He sez, Quit doing that.

If it dies when you hit it, quit hitting it.

The gas has to drill through the sheet metal... not.

Is the relay loose in the harness/mount? Or is the relay loose inside? Get a new one, they are cheap, and test it the same way, or swap two identical relays and see if the problem follows.

On a 87 one of those relays is the fuel pump relay and they do go bad due to corrosion and /or weld the contacts together(pump won't shut off)as he said replace it before you do any thing else.If the pump does not shut off it can cause some of the very problem's you are having.One quick check is to remove the gas cap,put you ear down close to the open fuel fill have someone turn the ingiton from off to on without starting it,the pump should run for a few secounds than cut off ,if it does not cut off the relay is the most likly problem. I would change it anyway cause if it killed the motor by messing with it ......it ain't right!!!!
