No spark from V8 electronic ignition

My 1986 Rangie V8 EFI has died down the South Coast, Moruya. I can't get any spark from the coil. The coil has been checked by an auto elec and it sparks fine on his test bench. I've fitted a new amplifier and a new coil lead. No change. I've checked the distributor pickup module, 3,500 ohms, that's good.
I'm about to replace the capacitor inside the electronics box under the coil, and am also cutting away the plastic that covers the circuit board that has the three wires going to it to check if anything is broken in there.

Any suggestions?

This weekend I'm going back down the coast to try to get it going by fitting a points type distributor. Then I'll buy a proper ignition system for it. I've been looking a Ignitor by Pertronix, any comments.

Can't shed any light on your efi problem but if you put a points dizzy into it you might have to put a ballast resistor in as the points only really want 9V instead of 12V like most modern coils provide.

As far as timing goes standard rover v8 should be 6degress before TDC.
hopefully the points dizzy has an external dwell adjuster on it to make adjustment easier.

I had a intermittant no spark fault on my 96 Disco.
I found that there was dirt/moisture causing a short on the low tension wires ( the Blue /white wires)coming from the from the Distributor to the coil. Check these leads, I found that that I removed the insulation tape covering where there is an inline connector, there was mud /dirt/moisture stopping correct connection. I cleaned it and all was ok.
