Quick recommendations
OBD code reader
Read fault codes from the engine.

Multimeter
The most useful tool for diagnosing electrical issues diagnosing.
Oscilloscope
To observe voltage changes over time that are too fast for a multimeter.
Test light
Quickly verify power/ground with a single touch.
T-Pin
Stick it inside the electrical connector to take measurements without disrupting the circuit.
Smoke machine
Detect leaks in any system.
Vacuum Gauge
Test vacuum/fuel systems.
Socket set
I suggest getting a good, well-equipped one. It is better than replacing a cheap set every year.
