Ignition problems
the expeditions had a problem with the rear wiper motor grounding out, i would try replacing the wiper motor first, as for the fuse blowing, it is blowing for a reason, fuses don't just blow. if the wiper motor does not fix you may need to have someone go thru the electrical pin point tests to find the short.

Fix miss fix miss fiers
There are frequent problems with the parts you already replaced. The crank sensor and cam sensor can affect firing. Check intake for vacuum leaks with a water spray. Also look at front passenger water jacket on intake, subject to decay and will spray water vapor on plugs.

Engine cranks but won,t start
Every 4 cycle gasoline auto engine needs three things: air, fuel and a source of ignition. If it cranks then the starter motor circuit and motor look to be OK. To check for ignition pull a plug wire and short it to the block with a phillips-head screw driver in the plug socket (leave a little air gap between the screwdriver and the point on the block. Be careful the output voltage from the coils can run as high as 40,000 volts and give you quite a jolt if you're not careful. If you get a regular spark from the screwdriver to the point on the block, it is likely that your ignition system is OK. If not then start trouble shooting there.
If ignition checks out OK then look for fuel starvation. Since it is a fuel injected motor there can be several places in the fuel delivery system to be checked. The first thing I'd do it crank it (no more than 30 seconds at a time unless you like replacing starter motors!) After three or four cycles of this with a non-start, pull a spark plug and insepct it by nose and fingers. If the plug smells strongly of gasoline and appears to be wet then fuel delivery is likely OK, check ignition.
I am not going into too much detail on checking the fuel system as that requires knowledge that I think an experienced mechanic needs to apply to the problem. Good luck! P.S. (Hint)The public libraries usually have "How-to" books on most automotive models in their collections.
