no spark to 4 cylinders
i think the root of the problem is the battery - won't charge to above 12.2V. a new one is on order but i was simply wondering if this could be the cause to not having spark to any of the 4 plugs. motor cranks over a few times and relatively slowly too. should i be seeing spark no matter how slow it cranks?
what do you think the problem is?

RE: no spark to 4 cylinders
Spark has nothing to do with engine turning over slow...Spark is just there to ignite the gasoline. If you took all 4 coils off the sprak plugs and left the spark plugs screwed into the clylinder, it would still tunn over normal, but it wouldnt crank....To me the slow turn over means the battery just doesnt have enough juice to turn it over. Maybe loose terminal on the posts or maybe just the bad battery.....Bad coil packs will stop the fire, but RARELY will they all 4 go out at one time....I'd go for the battery first, since the morot is turning slow. IF that doesnt fix it, i'm sure we can dig a little deeper....=-)

I'd be putting my money on the battery. Have you measured the voltage when it is cranking? If it drops low (11V or less) there will not be enough EMF (supply) to allow the coils to operate properly hence no spark.
Also Alexlittle, you may have a dry joint or a high resistance joint causing a voltage drop. You need a voltmeter to trace the circuit measuring voltage at various points until you find the fault.
Luck.
