2006 honda cbf 250 wiring diagram needed... or need to know what wires are what out of the cdi/ecu, I have tried everything and cannot find anything... engine has been put into gokart and need to rewire...

from ignition switch red wire supplies power from the battery to the ignition switch, black wires are live when the switch is on but have nothing to do with the cdi The cdi is supplied by the generator on your engine.Green wires from switch are all earthing wires.The black and white wire coming from the switch is the wire that puts the cdi to earth to disable the ignition in the off position .

What does ecu mean

Electronic control unit....basically this is the computer which controls the engine. You can google the code which is stuck onto the ECU to find out which model vehicle it is for. eg;6 cyl, 8 cyl, auto, manual, etc. Each has a different code.

Check engine light blinks on and off. rought idle

You describe a 'Misfire' condition. You'll need and OBD!! scanner to retireve any throuble codes stored in the ECU (Engine Control Unit). Once you know which/what code (i.e., P0300 - Random Misfire Detected, or P0302 - Cylinder #2 misfire detected, etc). then you'll know where to go from there - plugs, wires, coil(s), etc.

5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.

8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.

2 fuel injectors not working and I dont think the problem is the injectors. If the problem is not in the wires, what controls the injectors? 1990 chevy beretta GTZ 2.3L

what engine do you have? the 3.1 the injectors are all wired togther, so take a test light and check the plugs on all of your inj. use a separate ground to check the hot wires, then use a positive connection to check the ground wires. if you have power to all, it is probably the inj., the 2.0 is the same, the 2.2 or 2.4 may have a different inj system, but you can check the wires the same way. the different system works off of a cam sensor, but if it didnt work no inj would work at all. it then feeds into the ecm (car computer). but i bet its either a wire issue or a couple of bad inj.
