Wiring diagrams are often on the blower housing, or elecrical compartment. You didn't say whether you are looking for the unit diagram or heat kit diagram, which are considered seperate. If you are looking for the heat kit diagram, post the model number listed on the heat kit itself.

The connection wiring diagram is usually on the inside of the motor's junction box cover. If the motor has three wires at the junction box then these wires are connected to the three incoming supply wires. If there is more than three wires, check the motor's nameplate to see if the motor is a dual voltage motor.
General Motors released a yearly manual of wiring diagrams for the P-30 chassis. For example, the 1992 manual was entitled "1992 Electrical Diagrams and Diagnosis Manual Light Duty Forward Control Chassis, Value Van, and Motorhome Chassis Models". The GM document number for the 1992 manual was X-9240. They are sometimes available on EBay

Check your fuses, most likely be a fuse. Otherwise check the continuity of the wiring. You will probably need a wiring diagram, visit an autoelectrician and ask if you can buy a copy of what you need. find ure fuel pump relay pull it .jump pin no 30 to 87 and pump shud sound if it does then ure relay is bad if it does not sound then try the fuse .
I've not been able to locate many vehicle repair instructions online that provide diagrams. Your best bet is to get a Hayne's repair manual for your make, model, and year at an auto parts store - usually $24-30.
