2004 Honda CBR 600 RR fuel pump will not prime

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.

SOURCE: honda cbr 400 rr starting problem

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.

good luck.

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.

1991 Dodge Dakota fuel pump wireing. I removed pump and tested OK- Tried switching relays (all same in relay box) Still no cycling only a slight noise then silent. Ran 12-v (spiced) to left wire of 5.

engine cranking do you have spark at the plugs and fuel injector pulse? I don't know what testing you have done? I am trying to decide if more than one issue? Did you check voltage and ground at fuel pump connector, engine cranking? Initial prime is one thing but after that, if no rpm signal, no spark--no fuel injector pulse--no fuel pump. W/o rpm signal computer won't ground the asd relay. Any applicable trouble codes?
In my opinion, you can't bench test a fuel pump, I've seen faulty fuel pumps that would run up a storm on the bench but make no pressure when in the gas tank.

Hi, Gasper and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Fuel line to carburetor or throttle body pinched or kinked.
8. Carburetor float stuck.
9. Fuel injectors clogged.
10. Severely discharged or damaged battery, you need 12.5 volts or better and be able to pass a load test if necessary.
11. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
12. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and CDI box.
Spark plug cables in bad condition and shorting check for leakage in the dark, cable connections loose, or connected to the wrong cylinders.
13. Ignition timing incorrect due to a faulty MAP, CKP, O2, TPS, sensors.
14. Faulty neutral, clutch lever, or kickstand safety switch.
15. Faulty fuel pump or fuse or relay.
16. Faulty CDI box.
17. A stuck bent or burnt valve.
18. Tip over sensor needs a reset.
19. Check for engine trouble codes.

Fuel pump not working, will not prime, cranks but no start unless putting fuel in intake

Check voltage and ground at fuel pump, pink wire is voltage black wire is ground. The initial prime is only for key on engine off, lasts a couple seconds. You use a testlite to check voltage and ground.
Check voltage and ground for fuel pump relay. Also, you have an inertia switch, you have to check that.

For testing, you can use jumper wire at load side of fuel pump relay, the load side is that line with the arrowhead. When relay is energized that line moves to the other terminal and sends voltage to fuel pump, just unplug the relay, use jumper between terminal 30 and 87, terminal 30 is hot all the time.
The voltage and ground for the control side of relay is controlled by computer I believe, If the control side is the problem, I'd have to check wiring circuit and computer.
With engine cranking, you have injector pulse, also?

1999 lincon town car no power to fuel injector

Sometimes a crankshaft sensor does not send the signal to fire either the spark or the fuel injectors. If the fuel pump relay is not getting power, the inertia sensor will not have power either. The inertia reset is just magnetic and does not depend on having power to reset.

You can check for current at the Inertia sensor and at the fuel pump relay. You can also have fuel pressure at the test port without the injectors working, which is the easiest test of all,

You need the sequential firing pulse for the injectors. Have you checked the EEC Relay?

Back firing is caused but lean conditions suggest a fuel injector volume test. This requires a injector pulse generator. pulse each injector for same interval usually 100ms and record pressure drop and re prime line between each test for accurate values. If all is fine. remove valve cover check for broken valve spring or flat camshaft lobe. low rocker arm movement.

12ht wont prime

filling the filters before installing will make priming go more quickly.
once the pump is primed crack open the fuse line at the injector while cranking until you have fuel pulsing out, close it then move on to the next injector.
keep doing this until the engine runs smoothly.
it may start running before all the injectors have been purged so keep clear of all moving parts and a fire extinguisher handy would be a good idea.

How do you know if the fuel pump or just the strainer is bad? i've had to "prime" the fuel pump (turn key forward) for sveral months now in order for the car to start if i dont, then im stuck...

I personally don't think its either. Do this for a living. You have an electric fuel pump and in most cases if they go bad it just plain doesn't work. If it was the strainer you would have problems with fuel pressure while running at all times. As far as having to "prime" the system you could be looking at a loss of pressure somewhere but sounds to me more like a relay or an electrical problem. What I am saying is that as you turn the key to "prime" it, you are maybe not priming it and its more of a hit or miss on the electrical problem. I would check to make sure your fuel pump relay is working. It should engage for about 5 seconds after you turn the key. You can feel if it is engaging by touching it when someone turns the key. Also there may be an ECM relay thats not engaging at all times. Are you able to hear the pump turn on when you turn the key? If yes when it will not start is there power (electrical pulse) on the injectors when it won't start? I would just hate for you to drop the gas tank for no reason and pay for a pump for no reason. Pumps are bad or not bad. Work or doesn't work in 99 percent of the cases. Fuel pressure doesn't change that much either. If there is a blockage it's there or not. Just my opinion and I hope it helps. Good luck.

No injector pulse, no current to the injector

Check the pickup in the distributor as this is the cam sensor. The injectors run of the pulses created while the rotor is turning around. It should be a plastic disk located under the rotor button.

Im assuming this is a 3.9 ltr 6cyl?
any way there is always three things to check in regards engine not starting.

1. Compression
2. Spark
3. Fuel. "make sure you have fuel in the tank" first :)

If your vehicle is EFI

If you cannot smell fuel. Carry out these simple checks.
When the ignition is on engine off, Do you hear the fuel pump prime. This is noticeable by a short buzzing noise in the rear of the vehicle and then it will stop,

If noise is not present check the fuel pump fuse, then the relay, and last of all the fuel pump.

If the fuel pump is operational.
Make sure the fuel filter is not blocked and obstructing delivery of fuel to the injector.
If the fuel filter is ok, remove the injector plug from a injector and using a led circuit tester, or a noid lite. check for injector pulse.

If there is no injector pulse then it would possibly be a ignition module if this model of vehicle still uses a distributor

This only because I dont know if your vehicle is 3.2 ltr, 3.9 ltr single point inj, or 3.9 multi point inj,

ps: To check for injector pulse, using a LED TEST light just connect the test light in between the 2 terminals off the injector plug, and check for flickering of the led, this will say that the injector is pulsing.

A noid lite basically justs fits into the injector plug .

I hope this helps, let me know if you need more help.
