Is the injector order the same as the firing order?
Yes, but only if the engine has sequential fuel injection.
Look at the wiring diagram for the injection system.
If the engine computer (ECU, ECM) controls both the positive
and the ground side of the injectors, then it's sequential.
If the engine computer only controls one wire of each injector,
it is "bank fired", meaning a group of injectors (all of them for a 4 cylinder)
fire at the same time, and the fuel mist sits above the intake valves
for a short time before they open.
If the engine has throttle body injection (TBI, DPFI, etc. 1 or 2 injectors sit away from the engine where a carburetor would) then the injector(s) usually fire when the #1 spark plug does, and you can see the fuel spray with a timing light.
