Good Battery,
Engine turns over...will not start.
My guess...could it be one of the
four coils...and if so...how do I test
which one is bad...?
Could it be a fuse burnt out..?
I'm frustrated...!

Cranks but no start condition:

Fuel and Spark:
Get a helper disconnect a spark plug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coils resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
