I have to ask? How long since a tune-up? Are there any applicable trouble codes? As far as spark at the spark plugs, check the ignition module. Check voltage to ignition module with key on, pink wire with black tracer. If no voltage, check fuse circuit, fuse 6--20amp in relay center. Not only check the fuse, check the fuse circuit for voltage. During cranking rpms, it is the ignition module that controls spark, but, it has to see rpm signal, which comes from crank sensor. At the moment, I can't be positive which component or exactly where the fault lies. To reply, click on comment link.
