Question about 1999 Honda CBR 900 RR Fireblade

1 Answer

My 99 cbr 900 has no spark from plugs. Replaced the plugs and coil pack and still nothing. Wondering what coils ran what plugs to be sure connected properly. Battery seems fine. Have a cdi box on the way but also wondering if I should be hearing a fuel pump when I turn the key on?

Not getting any spark on my 1983 yamaha xj 900 secca. just replaced coil packs and igniter

Hi, Anonymous and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
3. 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.
4. Loose connection at ignition coil or plug between ignition sensor and CDI box.
5. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose, check for spark leakage in the dark.
6. Faulty ignition coil, pick up coil, trigger coil or CDI box testing needs to be checked with an ohmmeter at 70 degrees Fahrenheit
7. Faulty safety switches clutch, kickstand, neutral, off/on etc.
8. Faulty ignition switch.

Dead miss on one cylinder 99 sl2

A quick way to check the single coil pack if you know for sure which cylinder is miss firing and its setting a code you can swap the coil pack to another cylinder and see if the miss changes from one cylinder to another. If it travels to where you moved the coil then the coil is bad,if not you have other problems.

Bad coil pack

If your truck has spark plug wires, you will want to change those as well, as a bad wire can cause an ignition coil to short itself out internally.

I replaced the spark plugs, wires, coil pack, and it wont turn over. I hear the starter turning and the wine of the fuel pump and nothing.

You need to check if you have connected the wires to your coil pack correctly. Also check all the plug leads and make sure they are sucurely plugged in to the coil pack and on to the plugs.
If it was running prior to this and all your fuses are good then you may have mixed up the wires.

Ok I have 2002 Jeep Grand Cherokee, I have replaced the spark plugs and the coil rail but still getting the code P0351 and I was wondering if this could be caused by some kind of sensor?

The code indicates the coil pack or spark plug is malfunctioning. You can test this using an additional person. by removing the coil pack and spark plug, place the spark plug into the coil pack and ground the tang on the spark plug to the engine. Have someone start the engine and watch for a blue spark. if there is no spark, then the coil pack is malfunctioning. There is also ways to check the coil packs using a multimeter.

also, bee sure you didnt crack the ceramic part of the plug during initial installation.

No spark out of my 1999 cbr 900rr

Could be the coil pack probably a weak stator,. Try a pickup coil for the stator if you can get your hands on it way cheaper then replacing whole unit. Good luck.

Not getting a spark on my 99 cbr 900rr

The regulator does not affect the spark
If you have made sure the ignition is in the on position and the kill switch is in the run position here are a few things to check:
  1. Kick Stand Switch
  2. Nuetral Safety Switch
  3. CDI

Spark plug wires

Hi and welcome to FixYa,

Almost always, seated on the bike the lefthand ignition coil supplies cylinders 1 (extreme left) and 4 (extreme right) while the right hand supplies the mid 2 & 3.

Good luck and thank you for using Fixya.
