Was adjusting max fuel on 1HD-T and turned it down a bit. Idle lowered as a result and was about to adjust idle screw when motor stalled. Didn't seem like it stalled from lack of fuel though. Now it turns over but no start (lots of grey smoke when trying to start). I'm now noticing that the turbo lights and the A/T oil temp and glow plug lights do not illuminate in the dash when the ignition is turned on. Tips?
