I'm not getting any fire on cylinders 3 and 4. I replaced the coil pack on 3 and the engine is still riding rough. I checked the power going to cylinders 3 and 4 and they have power. Do you think the timing could have jumped?

Check spark plug, compression and fuel injectors on cylinders 3 and 4 and also test the crankshaft position sensor.

How do you test the crankshaft position censor? Do I ohm it out and if so what are the specs?

Ohm it out-it should read (440-570)-If it's not within range or specs, replace it. Make sure you zero your meter.
