So the intake hose will run from the smog pump to where? I removed the egr, plugged off one port in the back of the block and capped off another and removed the pipes. Was it one of those?You can leave it with the belt on. Does it still have the intake filtered or baffled?
With the intake hose removed they tend to suck in a bunch of dirt and then lock up. So leaving the pump in place is a short term solution.
Start looking for a shorter belt.
