Won't Start -- Protective Control Box Fried?

[oldav8tor]

1992 998 6.2L was running fine. Installed a new soft top then it wouldn't start...nothing, no glow plug light no cranking. Batteries are 12.2V and 12.3V. From reading other threads it seems if you don't get a "wait" light for the glow plugs the PCB may be fried. Any other ideas? Thanks in advance. Oldav8tor.

make sure you did not bump the shifter and in gear?

Thank you. It didn't occur to me immediately to check that but the next day I did and even cycled it through the gears and back to neutral but still didn't get anything.

Learned that the hard way with my 5 ton....

Are you sure its no wait light at all? I had thought the same thing. It wasn't until nighttime that I realized that it was flashing once super fast. Replaced the Glow Plug Controller and the wait light is functioning as normal now.

But even with a bad PCB shouldn't it still crank? I have a bad PCB and bad plugs, but it would still turnover. If it's not turning over at all, maybe something else has come undone.
