Hi "J"...You just can't be without a Rangie..just admit it !!!!

Could be as simple as the rotor arm tracking down to earth (Common fault).
To check this, and the HT output, unclip the dizzy cap and place aside, pull the HT lead from the coil out of the dizzy cap. Hold the end of the HT lead with a pair of WELL INSULATED pliers about 5mm above the brass wiper on the rotor arm and get someone to crank the engine over.
If a spark jumps across to the rotor arm, the arm is crap and should be replaced with a genuine Lucas, if there is no spark, check that the HT voltage s being produced by holding the lead about 5-6mm from a metal part of the engine...you should get a healthy spark, if not then either the coil, HT lead(s) or the distributor sensor which replaces the old fashioned points, could be shot.
If you are getting a good spark at the HT lead from the engine and not across the rotor, then the rotor is o.k. and you need to be looking at the HT leads or maybe even the orientation of the leads on the dizzy cap (Firing order).
There are none of the fancy crank sensors etc. on the Classic and the Ignition side of things is pretty straightforward compared to the P38, V8.
One other thing...the 3.9 is susceptable to block problems the same as the 4.0 and 4.6 engines fitted to the P38 so check the coolant and inside of the rocker covers for "Milk"

Must say that my old Classic, after replacing the engine, was far better than the P38 that replaced it...wish I had kept it !!!

Good Luck Bud.......:D

yep rotors can be a problem in starting the 3.9...but if ya have spark...shoot some starter fluid in the intake and see if it fires...
 
J should be pretty straight forward. Assuming the coil is actually O.K. the problem could be either the ignition amplifier or the pick up air gap. Before getting in to that though I would suggest checking the connections to both the coil and the ignition amplifier. The spade connectors that go on the coil are known to corrode, I have had this with my 3.9, also, the plug that goes on to the ignition amplifier needs to be pushed firmly on; again check for damaged wires.

If you check out the V8 section I have previously posted all the L.T. ignition checks - have a quick search and see if that helps.
