No spark from distributor to spark plugs
Just bought 95 disco 3.9 auto, and have been banging my head off the wall trying to diagnose the problem. Previous owner replaced cap and rotor, coil, plugs, wires, spark plugs. Good spark from the coil to the cap, but nothing going the spark plugs. Originally thought cam shaft sensor, but not sure if this model has one. Any thoughts or suggestions would be appreciated.

no camshaft sensor on that truck
are you checking spark with an inline spark checker ? or just going on the "no start" issue?
at this point I would double check the cap / rotor/ and proper firing order-placement of the plug wires.
if you are checking spark from the coil to the cap by looking for an arc at the end of the coil wire where it connects to the cap......you need to give it a good inch or so gap and should have a bright blue spark jump....anything less and the coil may be questionable......and then we can talk about the ignition amplifier module.....
