If both sensors started doing this simultaneously, then I would look for a problem upstream somewhere. Perhaps your voltage regulator has gone haywire? Not sure how the '87 wiring system is set up, though, so you would have to get feedback from someone else on specifics....
Thanks if Any Body Has Any Information On This, Write back,

The vehicle has the factory duel tanks with the duel tank switch on the dash beside the ashtray. The gas gauge will now only register 1/4 tank whether it's filled up or not, but still allows to switch tanks. There's definitely power to the switch because you can hear it trying to switch just like before when the gas gauge worked properly.
Do I need to drop both gas tanks and replace the sending units or is there something else I should be looking at?
Thanks, Dan
THanks,

As for the bulbs, they should be of the "twist and lock" variety, so pulling the cluster from the front to gain rear access should make the replacement process a breeze.
Move from simple/cheap to complex/expensive here.... it has to be one of those three things!
I apologize that I could not be of more help. The amount of visitation to this topic (other than to ask questions) seems to be rather light.
If not then the crank sensor gives a pulse for each cyl. The dist. tells it when it is #1. First check the dist. position by sighting straight down the rotor "contact" to the dist. housing. Crankshaft must be at "Top Dead Center Compression" on #1 cyl! The rotor should point to a mark on the housing. This is the ballpark position. I had the code after this step. I had to try turning the dist. housing a degree at a time, clear the code, start the engine, and see if the code returned. It may take a few attempts. It took me three tries. I got lucky. Good Luck.

Hahha! No kidding! Perhaps somewhat unrelated, but a couple years back a coworker's 1999 Silverado burned to a crisp when its fuel tank caught fire due to an electrical short in the fuel pump. She had started it with an autostart, so there were no occupants when it ignited, but the back seat area where her daughter always sat was naught but char. :surprise: She replaced it with a 2002 GMC Sierra, so I hope that is not a common problem!
