Question about 2004 Honda CBR 600 RR
I have a CBR 600rr that doesn't prime the fuel pump doesn't have fire or doesn't pulse the fuel injectors...I've checked all the relays I've tested the computer on another bike I've checked the kill switch I've checked the tip over sensor I've got a new ignition switch and tested the fuel pump...also the injectors and the coils have 12 volts going to them any ideas where to search from there?
Hi, Only_chevys the following is a systematic procedure for diagnosing fuel pump issues designed to keep "DRACHMA" to a minimum. If you need parts check with Amazon and eBay first to keep costs down.
1. If your pump does not turn on check the pump fuse and relay and all wiring including connectors for corroded, broken, or loose pins/sockets.
1. Normal fuel pump pressure is 3-5 PSI.
2. Check any rubber or plastic tubing for age-related pinholes by removing and plugging the ends that connect to the fuel valve and then turn on the ignition switch and watch for fuel streams exiting the pinholes, if any exist, replace tubing as necessary.
3. Check for a clogged a primary fuel filter that comes off the bottom of the pump to screen out big rocks and clean as necessary.
4. Check for a clogged secondary fuel filter that's outside if applicable by removing it from the system and replace it with a short splicing tube turn on the ignition switch and recheck fuel pressure if pressure increases to normal pressure you need a new secondary filter.
5. If all the above check out OK and the pump is not functioning properly then you need a new fuel pump.

i could not find a schematic of a 96 cbr400rr, so guessing this bike is not from the USA. however, there should be a master fuse near the battery on the positive side mounted to the battery box somewhere. i would check this fuse first to see if its burned out.
also, is battery fully charged? might have to top charge the battery to get good juice if its old (>3 years) and been sitting for a bit.

hi, each lead has the specific number on it. if you do this correctly then they genrally give you an idea to where the sit in the coils( the way they bend :-) ) also i believe the coils are better off been attached to the frame once you are sure leads are in corect order and possitioned correctly in the coils.i just presumed the coils neaded earthing. make sure battery is pleny charged as a bad battery can just hinder. it is also very easy to flood the bike so just check the plugs again. if they are unusually wet then dry them off and try again . otherwise maybe try cleaning all electics.
hope this somehow helped

1. Obtain a new transponder key.
2. Grind the key in accordance with the shape of the original key.
3. Apply 12V battery voltage to the ignition pulse generator lines of the engine control module (ECM).
4. Turn the ignition switch ON with the original key. The immobilizer indicator comes on and it remains on.
*The code of the original key is recognized by the ECM.
*If there is any problem in the immobilizer system, the system will enter the diagnostic mode and the indicator will remain on for approx. ten seconds, then it will indicate the diagnostic code (page 20-5).
5. Disconnect the red clip of the inspection adepter from the battery positive (+) terminal for two seconds or more, then connect it again. The indicator remains on for approx. two seconds, then it blinks four times repeatedly.
*The immobilizer system (HISS) enters the registration mode. Registrations of all key except the original key inserted in the ignition switch are canceled. (Registration of the lost key or spare key is canceled.)
The spare key must be registered again.
6. Turn the ignition switch OFF and remove the key.
7. Turn the ignition switch ON with a new key or the spare key. (Never use the key registered in previous step.) The indicator comes on for two seconds, then it blinks four times repeatedly.
*The new key or spare key is registered in the ECM.
*If there is any problem in the registration, the system will enter the diagnostic mode and the indicator will remain on for approx. ten seconds, then it will indicate the diagnostic code (page 20-6).
Keep the other transponder key away from the immobilizer receiver more than 50mm (2.0 in).
8. Repeat the steps 6 and 7 when you continuously register the other new key.
The ECM can store up to four key codes. (The four keys can be registered.)
9. Turn the ignition switch OFF, remove the inspection adapter and connect the ignition pulse generator connector.
10. Turn the ignition ON with the registered key.
*The immobilizer system (HISS) returns to the normal mode.
11. Check that the engine can be started using all registered key.
If that doesn't work,You will need to go to a dealer and have the keys reprogrammed.

2 blinks is a MAP sensor performance problem.
Check the MAP sensor vacuum hose connections if its ok then you will need the ECM test harness cable from Honda to diagnose further.
