Lawn mower 6.5 that's getting very faint Spark. was left out in the rain so I clean the Magneto the coil I'm still getting faint Spark any help out there thank you

Clean the fly wheel and then check the points. The gap between the megneto coil and fly wheel is minimal. Also check the spark plug lead is clean also. Then get a new spark plug and it should work.

I own a 04 Suzuki Verona the problem started with a loss of power following a check engine light which started flash the problem was initially intermediate and I change the coil packs and spark

Did you ever get the check engine light diagnosed? You can go to Auto Zone and they will plug a code reader into your system for free and tell you what it means. If you are that dependent on your vehicle, you may be better off paying to diagnose the problem with a mechanic who has good diagnostic equipment.

Hi Steve Griffith
Check your ground, if you are getting a faint spark, then normally the ground is not good

My grand prix shakes when i go up a hill or start out. i have good tires

If the shaking is caused by the engine missing (a misfire on 1 or more cylinders), then
check your (a) spark plug wires - pull each and check for continuity/faults/burn marks/etc., (b) spark plugs - pull each & check for fouling/faulty/etc.
Another good check for spark plug wires is to park in a dark area at night (open garage with the
lights out works), run the engine and observe the engine operate in the dark - little lights caused by
faint arcing means that the wires are leaking electricity to the engine block, instead of delivering it
to the spark plugs, like they should.
Your particular car has a Distributorless Ignition System (DIS), consisting of an ICM (Ignition Control
Module) connected to an individual coil pack for each pair of cylinders. You'll need a
HEI (High Energy Ignition) ignition system tester (about $30-$45 any auto parts store) to test
these coil packs, which I have found quite easy to replace (usually a couple of 10mm cap screws).
Since the car shakes only when accelerating or going uphill, I tend not to think that suspension
components of the car are at fault.

My jd x324 will not start. it has fuel, we had a faint spark at first with new plugs we now have none.

Check the gap on your plugs first, than you must lean towards the coil it may be faulty or bad. Then you need to replace coil assy. You should see very strong spark with new plugs.
