96 FXSTC front cylider dead
any one have any idea as to why my front cylinder will not fire? new coil, new ign, new plugs and wires. I pulled the front plug and can smell fuel, but it still looks new and the pipe is not even getting warm. I rang everything out with a multi meter and all seems well. I posted this in the new member section as well.
any help is greatly appreciated.

If you have determined that the injector is squirting fuel, then check for an output pulse on the coil for that cylinder. If none, there is a problem with that coil even if the rear cyclinder is firing. Did you replace the coil and ignition with a separate fire for each cylinder type?

yes i have a new coil, wires and plugs, i turned on power and have voltage going through the plug wires to the plugs, the same voltage to each plug, i can smell gas on the front plug it just will not fire. I dont understand what you mean when you say a separate fire for each cylinder type.

I pulled out both plugs turned out the lights in the garage and turned it over i could not really see any spark with either plug, i will try that again and look a bit closer.

Do i need to ground the case of the plug to get spark? i pulled both and got no spark from either unless i am doing it wrong. I did feel powerful shots of air coming from the plug holes (both cylinders) so it seems that there is compression. I don't know what to do now...

Yes, you need to ground the plugs to the heads to get a spark or you can damage the coil.
Not sure on a 96, but the newer bikes won't fire unless there is compression, most use an extra plug, ground it to the head and turn it over and look for spark.

I just tried some voltage checks, I believe that a coil is higher output than battery voltage, correct? I put my meter leads to the front plug wire and ground and had about 11.5 volts with power on and when i tried the starter switch it dropped to about 9.5 volts, when i did the same for the rear plug wire (rear cylinder is working, and starts the bike) the voltage shot up to around 22.5 volts. Shouldn't they be the same for both cylinders?
