Bruce,
Sounds like your immediate problem is electrical. I would get a
helper to find out if you definitely don't have a spark while you
crank the engine - this is the fundamental start of your diagnostics.
If no spark, then get a Bentley manual and go through the diagnostic
checks that are explained. There are many reasons why you would not
get a spark, such as:
* ECU dead (very unlikely)
* Coil dead (unlikely)
* Hall sender dead (unlikely)
* Rotor bad (unlikely)
* Ignition switch bad (unlikely)
If spark, then its probably a fuel delivery problem. Again the
Bentley manual has lots of diagnostics you can do. Problems areas
are:
* TempII sender bad (they do go bad)
* AFM bad (they do go bad)
* Fuel filter clogged (maybe)
* Fuel pump dying (good chance)
* Grounds (all those brown wires) bad (not likely)
* Fuel pressure regulator (not likely)
Given what you have mentioned so far my guess is:
* there probably is a spark from the coil to ground
* the distributor cap or wires may have been repositioned wrongly
after you checked the wires and changed the plugs
If you get it running, I would then work on the original fuel delivery
problems:
* check fuel filter and pump
* check fuel pressure
* check throttle switch
* look for vacuum leaks
* remove and reconnect all the electrical connections you can find
(this sometimes helps re-seat a bad connection)
* get yourself a volt/ohm meter and do the Bentley diagnostics
You have a some work ahead of you to pin this down.
