Cheap ways to diagnose Sensors

[newbuick]

I own a 2000 Buick Century and am looking for cheap ways (I have a digital multimeter and a logic probe) to check out the following.

Crank Sensor
Cam Sensor
IAC
Ignition Module
MAF or MAP
Coils
Fuel Pump/
Wheel Speed Sensors
EGR
Fuel Injection System
Any and all other modules, sensors etc.

Any down and dirty method to check these would be greatly appreciated.

I have one method of checking the fuel injectors to see if they are being triggered. Just use a 194 bulb (very common) and bend the metal wires down and insert into your injector connection and if it lights up while you are trying to crank the engine the injector circuit is more than likely OK.
Thanks

well i'd say a multimeter will do the trick...that's about as cheap and simple you can get, really.
