i have a 2003 f4i that wont start i have no spark, no injector pulse. my pulse generator is working. i have power to all my ignition switch wires. im afraid i have a cdi box problem but im not sure. is there some hidden fuse i may be missing or something. please help.

 

Sois yourbattery good (Gauge/Light's turn on)? I would checkthe 30ampmain fuse, make sure you pull offthe rubber housing and don't mistake it for the spare.

 

battery is good so is the main fuse. im going off an f4 manual so i wasnt sure if there was some other fuses that i didnt know about.

 

How many miles? I find it hard to believe it would be the ECU. Could be the regulator but my money would be on either the spark plugs or a bad switch (kickstand, clutch, etc). You sure its not getting a spark? Just want to make sure its not a fuel issue.

 

it has 4500 miles on it. if it was the side stand switch or the clutch switch it wouldnt crank which it does. it is not getting any spark out of the coils, and i hooked a noid light to the injector connector and it is not pulsing. could a regulator make it not start at all even if itcranks?

 

It's possible. But seems you would have noticed problems leading up to this. If its not part of your charging system then I’d say plugs butI can’t believe you’d need to change them at 4k miles.Did your bike take a spill? Could be your Tip-over switch.

Also, If your kickstand switch is faulty your bike will still crank but won't fire.

 

good to know on the stand switch the plugs are new but that does not have any thing to do with the injectors not pulsing. the bike has not been down so i dont think it is the tip over switch but where is it on this bike so i can check it?

 

tip sensor is between the lights on front upper fairing...
