It could.
It could.
A variety of things could cause a no spark condition. The distributor, the coil, the computer, etc. If you can get someone with a code reader out to read the computer codes that would narrow down your search.
Yes. On some vehicles, the Crank Shaft Position sensor tells the computer that you are trying to start the vehicle. Without that signal, the ECM will not control the spark coil.
Trust me your 1/4 coil is junk. you dont need all three
That would be very rare.
No spark would usually be the ignition coil.
bad spark plug wire.
A blown radiator hose could not cause a 2000 Dodge Durango to not have spark and not start unless the heat damaged the computer in the vehicle. Sometimes when an engine overheats, the computer that controls the firing can be damaged.
It could be spark plugs or coil packs. Auto Zone will check your computer codes for FREE. This way you won't be guessing.
Spark plugs don't smoke. A bad alternator would cause a dead battery.
Fuel injectors are usually powered directly by a fuse and then grounded by the engine computer. So no power means just that No pulse means bad ground to or from computer, The engine computer usually has a separate ground for this. The last time I had to fix this some doh head had wired his amp to the same ground.
Bad spark plug, bad spark plug wire
It means the computer is detecting a misfire on those cylinders, the most common cause is worn spark plugs or spark plug wires. I would recomend replaces both then clear the computer codes and see if the service engine light comes back on.
