Half way to fixing suspension (fixed)

Have I done something wrong?
Two days ago, replaced the dessicated and filters in the air dryer. I also replaced the exhaust o ring, the cap has no cracks in it.swapped a couple of o rings on the brass fittings too. The pump now runs with cutting out and giving a fault.. but I'd I try to lower or raise ,it tries and then cuts out. The code says air supply. The rear seems to go up and drops easily, but the front does nothing. I know there is pressure in the resovior. I and I believe there is also pressure I'm the front line leading to the front valve block. Speaking of valves, are they meant to be open or closed according to my code reader? Any way the reason I know there is pressure is because I loosened off the connector from the center valve block to the front and air was released. The white lines on the 4x4 screen at the front wheels are sometimes white and sometimes flashing red, dependant on what mess I'm getting into cycling the ignition, clearing the code, which also sometimes says slow to fill resovior,.also noticed that after clearing the code then turning the ignition on, or perhaps after starting the engine, both the up and down orange lights are on and other times just the down and locked are on.
 Mods:

LED rings in front lights,
Hids4u all external leds,
Rears removed,
D4 rear lights with hids4u reverse led,
Clear repeaters,
Side steps,
Mud guards,
Roof Rails - removed,
D4 Modded Grill,
20" stormers with grabbers,
EGR blanked and removed

Next: remap - BAS? Bluefin?

Oh just to add, I'm going to spray around the front valve block today and undo the feed pipe to see if air is getting there.. place finger over the pipe and see if air is leaking else where.

Quite often the centre valve block is the problem. If you have taken the front valve block off make sure all little plungers inside the valves are free to move as they sometimes get stuck and pipes are in their correct connection.

So, the motor sounded a bit rough when running so decided to get a new compressor. Got another Dunlop one, also I think perhaps the thread had gone on the feed line for the centre valve block on the air dryer, because it would nip up tight, it would keep turning I feel. So put the new pump on and relay. Let it run for 5 mins, cool for 10 and run for 5, now good as new.
