The ICP pressure has to be 500 or more for it to start. If he's just watching the ICP and it's showing 130 psi, it won't start but that doesn't mean the pump is bad. Only way to know for sure is to command the IPR valve close and apply a minimum of 100 psi of air to the system through the ICP port and listen for leaks.
