well, as one of my x-mas gifts i'm wanting to get this fixed....

I don't belive the fuse is blown so i'm thinking eather a whole new motor or something is wrong with the wiring.....

What do ya guys think?

Put about 300lbs in the trunk and see if it raises itself up like it'* supposed to.

Get power to the pump and see if it comes on to verify it works. There'* three wires, Exhaust solenoid power, Pump power and Ground.

well, i know it dosen't work. at WCBF we tried to raise the rear end for the drag racing by having some of us sit on the truck, but it never pumped up....

I'll try to check the wires first thing tommarow morning...

You need to do some experimentation to see what exactly isn't working.

Disconnect the level sensor rod and rotate it fully in the loaded direction to see if it senses.
Mine stopped working once and I did this. Rotated it in both direction fully a few times. It has been working ever since.

Check for open circuits.
If it still doesn't work, remove the pump and power it separately to make sure if it works or not.
Try taking it apart if it doesn't. Nothing to lose and you may learn something.

The pump is very simple, 12v motor, direct connect crankshaft, 1.5" bore, reed valves. If anything, I would assume the motor would be the first to go.

does someone have a part # for the pump if that'* what is out?

I've got them for the whole system.

Does the pump motor turn on?

no

Apply 12V to the pump motor, Now does it come on?

what cars have this option ive never heard of it. whats it do and how doe sit work?
