It sounds like the engine is cooking up the plug,, if a new plug gets you started again once you have fitted it, its not the bike's spark,,,its the old plug,, its burnt out,i think the carb is running vey week,, and this makes the engine run very hot,,,it could melt a piston crown !!! have you tinkerd with the exhaust pipe in any way? as this will throw the card way out of tune,,,and they sound very noise too, if you try a hotter plug in the bike it should sort out this sparking problem,,,mine eat plugs at a set a week,,,i had the wrong pipes fitted to my bike when i got it,,,

JD JS45 walk behind mover. Starts, runs fine for 5 minutes, then stalls, won't restart till i pull the spark plug and cool the motor, plug down. then same thing starts, runs for 5, stalls.


Probably either a fuel or a spark problem. You need to check for the presence of a good spark immediately the engine stops - by using a spark gap, a spare spark plug or a propriety spark indicator.

If the spark is found to be absent the fault is likely the ignition module but check all connections and the stop switch operation before replacing.

If the spark is present then the fault is probably fuel-related and is the sort of thing a tiny droplet of water in the carb could cause...

1996 toyota camry 4 cylinder. Stalls out every week or 2 but runs good in between. Nothing particularly showing on diagnostics


Can you duplicate the problem at home ? You would need to figure out if it is lack of fuel or spark to proceed with testing.

2002 malibu will not start when cold. After it starts by priming it then starts fine.


ever tune it up, try new spark plugs. gapped to spec.
starts fine and runs fine, not said the latter....????

Cold starts are the hardest, takes
these things to start good. cold.
1: go winter fuel (if cold out, isit? then winter fuel works best)
2: a good engine and good spark plugs, (hot spark)
3: good cold start fueling,
to get #3 the modern car 89- now. needs a working and accurate
ECT sensor, this tells the ECU exactly how much fuel to use.
if the ECT reads warming than REALITY, the fueling will be weak
and may not start or stall fast.

no location stated, nor if car is a daily driver, that is fresh fuel
every week,,,,

Motor stalls when driving then starts and stalls right away.


Replace the distributor's magnetic pickup located inside the distributor surrounding the distributor shaft, the only other thing thankfully on this ignition system if memory serves me on the f 150 straight six 300 cu inch is the dura spark ignition control box, of course do the obvious tune up parts replacement dist.cap rotor,plug , sparkplugs before spending the $40.00 - $50.00 bucks on the dist.. pick up, you may have a weak a fuel pump check for adequate fuel pressure at carb 7 - 10 lbs.

Running fine then wont'nt start


You will have to pull a spark plug out to check that you have spark when cranking the engine,while you have the plug/s out do a compression test to determine health of engine and wether it is in fact giving compression,eliminates other potential faults if compression is good.If you have compression(around 140 ish)and introduced fuel and it wont fire up it only leaves electrics as the fault.3 major engine requirements to run Fuel,Compression,ignition.When checking spark at night is best as you can easily see wether you have the correct type of spark,Blue and if its quite you will hear the spark as well.Your fault is consistant with ignition module,coil or lack of power to ignition.Faulty modules will give a spark but its too weak to ignite fuel and the spark will be yellow in color.Let me know how it goes.Good luck
