If the pilot light is on and no hot water, then the regulator is not turning the gas flow on. The commonest cause for this is a faulty thermocouple. This is a thin copper tube that's heated by the pilot light and relays a voltage to the regulator. This can be changed by a competent handyman in about 1/2 hour. The part you need is available in many Plumbing stores, best one is Honeywell Universal Thermocouple, costing $8-10. Installation is intricate and you need a good flashlight, very small wrenches and patience. The copper tube is delicate, be careful not to kink it.
