No spark in rear cylinder

Any ideas of what could be the problem, when there is no spark in the rear cylinder. We've replaced the gas, plugs and the rear ignition coil. Would you recommend that we a) sell the piece of ***, b) take the bike to a repair shop and pay up, c) try to replace something else, like the whole ignition module or something else we've not yet come to think of?

IT sounds like it is the pickups not working (.telling it to spark) if not then it will be CDI UNIT OR ENGINE GENERATOR COILS

SOURCE: no spark

It sounds to me like the repair shop has connected the ignition wire ( the wire going to the + side of the coil ) to the wrong switch terminal. Take a volt ohm meter and connect the ground wire to the negitive ( - ) side of the battery and expose the ignition switch terminals. With the switch in the OFF position check for volatge on all the terminals. Make note of any terminals showing a 12 volt reading. That is probably the feed line from your battery. Turn the switch to the ON or RUN position and check for a terminal other than the one which gave you a reading before. note and mark this terminal. Locate the coil. There are 2 thin ( 18 guage ) wires attached to the coil. One goes to the distributer and the other goes to the ignition switch. Isolate that wire and reattach it to the connection on the ignition switch you marked earlier...
Good luck,

how old is the gas it may have a lot of water or junk in it.drain the bowl on the carb and drain the fuel out of the tank, check the petcock screen inside the gas tank. also i would not spray start fluid into the plug hole, it could blow a hole in the top of your piston,spray a little right into your air cleaner or carb.good luck

First you'll need to get a jet kit from West coast star. Then you'll need to jet the carbs to run equally. This may take some trial and error. Another thing that worked on my bike was the upgraded coil kit they sell. It's almost double the voltage of the stock coils and comes with better insulated wires for a more uniform resistance. I haven't had this problem since. It'll make the cylinders fire evenly and save you from those pestiferous fouled plugs. I hope this helps.

SOURCE: 2007 yamaha virago won't start - replaced spark

it's not that your not gettin gas it's that the gas is not getting thru the carbs to the engine. your bike will probably start w/choke on and then die, your jets are clogged and happens to most bikes that are stored w/gas in the carbs.,,,clean them if you know how or take it to a trusted mech...good luck to you...Tim

My v star 650 is loading up in rear cylinder. I have clean the carbs. Put new pick up coil and stator. Still spitting gas out of rear cylinder pipe. Dont know what else to do.

Not trying to seem like a jerk but did you replace the spark plugs? It may still get spark but it can sometimes be too weak to get ignition (check by pulling the plug out, putting it back on the boot, touching the plug to something ground on the bike like the engine, then turn it over to see if spark is jumping the gap). The obvious thing is that you're not getting spark, the next thing coming to mind is good ground. Hopefully this helps.

1993 Nissan 300zx running on 4 cylinders

What did the spark plugs look like when you took them out of cylinders 4 & 5 that you say are not running. If they are wet and black and smell like gas, I would guess you have back spark plug wires going to those cylinders. If they looked about the same as the other cylinders, or a tannish color and dry, then I would guess injectors.

I have a 17 hsp 4 cycle engine..model number OV49OEA... I've replaced the spark plug, fuel pump,and it just will not start...any ideas?

This might sound odd but if you remove all gasoline and I mean all of it, use a syringe or baster if need be, then replace all gas with fresh it may do the trick. Also, you didn't mention if you checked your oil? You should change your oil, and be sure the oil stick level is correct also. Each spring you should change the oil, the spark plug, clean filter and use fresh gasoline, it will make all the diffference. Good luck!

2003 mustang cylinder 2 misfire. I changed the spark plugs and wires. Its still have code p0302. What should I do next?

A code P0302 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer

Possible Solutions:
* If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
* If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Keep us updated.
