checked for fuel, yesspark, yesenough gas in tank, yestiming should be okay since before it sat it was perfectly finechecked connections to everything and it was oki know its not the blue starter relay near the battery cause it cranksi ran jumper cables just to make sure the battery wasn't drained, no gotried to push start it, no go

i did notice that it seems to crank slower than it should which would lead me back to the starter? but wouldnt a push start work then?

help please

Unlikely to be your starter. I wonder how long gas remains good?

If you have spark and fuel, it should start, unless you have a spun bearing or some other dead-motor issue. I have an old Dodge pick-up that will lose fuel pressure if it sits too long, and you have to just keep pumping the gas and cranking the starter until fuel gets to the injectors. It can take several minutes. But that's a throttle-body-injected engine; I wouldn't think that could happen to an EFI car.

I fits cranking too slow, you can flood the engine with gas and foul out the sparkplugs. The engine is not spinning fast enough to actually start, but fuel is being sprayed into the engine at the same rate it would if the engine was turning full speed.

If you have a great battery and the starter is still turning slow, maybe the starter, or a weak ground, or connections at the battery.

With a good charge, there should be no reason your starter should turn slowly.

thank you that was informative. i already bought new ngk spark plugs. im gonna recheck the grounds and maybe add some additional grounds.
