What's the difference in the firing order on a 1997 318 or a 1998 318, is it the same or does something have to change cause of the timing in the computer?

Did you set the gap on the new plugs to factory settings before putting them in? If not, they may not be the right gap.
Also, any number of other issues are possible such as:
1. Wrong plugs
2. Damaged wires when removed from old plugs
(Plug connector wires can be easily damaged when removing from old plug if just pulled off and special tool isn't used.)
3. Stripped threads on plug allowing gas blow by and poor compression.
No. (2) seems to be the most likely cause without knowing anything else. A new set of ignition wires after 15 years of service is not something frivolous to do and money well spent.
distributor cap and rotor problem - there is your problem. If you do not put those suckers back in the same exact position, with the exact same markings, it will cause the car to fire the spark plugs at different times, causing miss fire and some times no firing at all.
+reason it will not start is because compression is low caused by bent valves no doubt ,but check it out first as some engines are valve free like the opel corsa from around this year and the fiat punto but i do feel the compression is low ,remove all the plugs then crank it up and what compression you have ?
if you already did a tune up, make sure you have the correct firing order. Ford made 2 different 5.0 one was for the mustang another for the truck. the mustang 5.0 firing order started 1,3,7,2,6,5,4,8 the truck firing order if I can recall correctly started 1,5,4,2,6,3,7,8. also might want to check or replace fuel pump.
You can't change the 'order of the pistons' but you can change the firing order if ignition wiring is swapped and this will definitely cause problems such as not starting.
The firing order is 1-2-4-3 so you need to trace the ignition wiring to ensure it is correct.
When I change timing belts, I always rotate the engine by hand and check the timing marks several times before trying to start it; this can prevent collisions between valves and pistons which is possible in some engines (interference) and very damaging, even nearly fatal and is fairly easy to be 1-2 teeth off on the first try.
This generally won't damage the engine but will make it behave very strangely or it may not start at all.
If you are certain of your belt installation, you need to check for spark by removing one plug wire or the wire from the ignition coil and placing it and inch or so away from any grounded metallic part to see if you have spark.
It should be a pretty fat blue spark if the ignition system is healthy although it will always appear weak in sunlight.
If you have spark, then you need to check fuel availability.
The fuel rail in most injected cars should have a fitting that resembles the valve on your tires but is a different size.
Turning the key to the start position briefly will pressurize the system and pushing the center pin is very briefly should cause fuel to spurt from it; keep your eyes protected when doing this.
I have the same truck I've been looking for information on a different subject. I am an ASE technician I may know what might be causing your problem. First off the white wire on the coil that goes to nothing is your test wire it's not going to be hooked up unless you are performing a test to ensure that the coil is working. Just changing parts often times does not solve the problem and it can become very expensive and make things worst for the next guy to fix.
it's going to be in one of two systems Fuel or Ignition since you just did things to the ignition system I'd start looking there check the firing order needs to know what engine you have before I can give you the firing order. is this a V6? V8 5.7? what all did you replace during your tune up? it could be that one of the plugs are not gaped correctly or tightened down which could cause damage to the head requiring the valves to ground to correct the problem.
Your catalytic converter may also be causing the problem one the et hot and melt they start blocking the flow of exhaust.If you would like to read more on that check out this site it has some very good information. http://www.aa1car.com/library/converter.htm
If when you changed the distributor cap you misplaced the wires in the incorrect order you could have caused a misfire. When looking at the cap the correct firing order for a 4.3 liter is 165432 going clockwise. Also if you loosened the distributor hold down bolt and turned the distributor even slightly you could cause a misfire.
