I'd suggest getting a chilton or Haynes book for your car first. Very handy! If no spark, you can test the coil with an ohmmeter, and test wires to it. Another possibility is wires to crankshaft position sensor shorted, or sensor is bad. This sensor tells computer when to fire, and if bad, you get no spark situation. Also check any fuses that have to do with ignition.

Sounds like your spending alot for this problem.....if this problem is only one cylinder then changing the fuel pump won't fix it...try removing the plug wire to each cylinder one at a time while running and monitor the RPM drop for each cylinder, they should be EVEN....If not thats the bad cylinder....at this point you need to check the cylinder compression in each cylinder...they should be within 75>80% of the highest reading..if its lower you have mechanical problem..(valves/piston/etc)...if good compression then your problem is fuel/electrical..this requires testers if you got them great.... if not then....at this point I suggest take it to a dealer/shop to save you any more undue parts cost...hope this helps you..GL
SOURCE: changing spark plugs on my 96 ford contour
A set of spark plugs usually requires replacement after about 20,000–30,000 miles (32,000–48,000 km), depending on your style of driving. In normal operation plug gap increases about 0.001 in. (0.025mm) for every 2500 miles (4000 km). As the gap increases, the plug's voltage requirement also increases. It requires a greater voltage to jump the wider gap and about two to three times as much voltage to fire the plug at high speeds than at idle. The improved air/fuel ratio control of modern fuel injection, combined with the higher voltage output of modern ignition systems, will often allow an engine to run significantly longer on a set of standard spark plugs, but keep in mind that efficiency will drop as the gap widens (along with fuel economy and power).
When you're removing spark plugs, work on one at a time. Don't start by removing the plug wires all at once, because, unless you number them, they may become mixed up. Take a minute before you begin and number the wires with tape.
Be sure not to use a flexible extension on the socket. Use of a flexible extension may allow a shear force to be applied to the plug. A shear force could break the plug off in the cylinder head, leading to costly and frustrating repairs.

I'd be looking at removing IAC valve, and cleaning it out with throttle body spray cleaner, and checking mounting gasket as well. Usually some success with cleaning it & spray ports it came out of, but if not you may need to replace it.
SOURCE: car died while driving checked fuel pump ok and
The spark is to weak change the crank sensor.If that does not solve the problem then its the coil pack that needs to be replaced
SOURCE: i have an 2003 ford expedition that just stopped .
Probably the inertia switch for the fuel pump..You owners manual should show you where its located..See if the button has pop up ..If it has push it back down until it clicks..If it wont stay down then hold it down and see if it will start..If it does you will have to replace it..If thats all good then check the relay for the fuel pump..
