1987 Burb, 6.2 Diesel.. "start engine" light dont work

no idea why, but we had it running this morning and the start engine light wont come on. we had the key on for 20 mins and still nothing. We were told theres something you could cro0ss in the engine bay and it would start but we have no idea. The "water in fuel" light comes on but the start engine doesnt, and they are side by side. When it was running thhis morning the engine start light was working, and then after we swapped the diff it was just flickering on and off and now its just completely off. Any ideas??

glow plugs are known to go bad in the old 6.2's. likely the start engine light uses a heat sensor on 1 of the chambers to come on when the temp in the chamber comes up to a point the engine will fire, no heat, no fire, unless it's a hot day.

We had the same problem in a 85 Chevy pickup changed the glow plug solenoid and it worked fine
