Fuel injector diagram
???
Injectors are 1 thru 6 same numbering as the cylinders
3 6
2 5
1 4
front
All the fuel injectors have a common red wire that has 12volts with key on
Each injector will have 1 ground wire of a different color that runs to the computer, the the computer Grounds the injector to open it to add fuel to the engine
The injectors are only grounded for milliseconds, so to test if an injector is getting a ground signal you use a Noid Light, it plugs in between the wiring harness and the injector, and will flash when injector is grounded by computer, engine cranking or running.
Flex Fuel used slightly higher "pound" injectors than gas only, maybe 24lbs, with regular being 19lbs
