what did you do to it before it stopped working ..

try to close slowdown if you have one in system if it lifts your dump probablky has debris in it ..

could also be a or broken missing key

if the pump spins, then the motor works. if the pump spins but the car dont go up you could have a bad check valve or the pumphead seals are out or the pressure seal is out. usually even with a pressure seal being out you still get some pressure in the lines so it should come up a lil bit. and if the check valve is bad sometimes the car comes up a lil bit too but drops just as quick as u left off the switch....

if you hear a grinding noise when you hit the switch and your ride trie's to come up your seals in the pump head are bad

so kingfish how do you check the pump head with the jumper cables
using jumper cables is a way to test to see if u have a bad motor or bad noids.....u cant use jumper cables to test for the pumphead. u basically need to either swap the pumphead with another known good one. or just rebuild the pumphead anyways and put in a new pressure seal
