I have a low crank no start situation by dash lights are on but when I turn the key nothing but I can jump the relay in the starter turns fine I even replaced the starter change the ground and checked all the fuses still nothing not even in neutral and I also change the safety neutral switch
The best fix for your suspension is to replace it with regular suspension. The air is expensive and a pain to maintain. Once you switch over, no more suspension problems...forever...
Check the fuse and test for power at the connections you made to make the compressor operate.No compressor, no air bags get inflated. Also, test the level control that limits the rise at the center of the rear axle. It has a lever to actuate it. Guscars.
