Didnt think a 93 model would have an alarm spider? my 95 model hasnt. I
believe 96 models have the ones with more than one button on the remote. I
was told single button remote models dont have the alarm spider?

Has anything been done to the engine since it last ran ok or did this just
occur from the last switch off?

I had a mystery failure on one of my V8s, the rotor arm went short to the
post inside. Took much head scratching to solve that one.

If it's "always a pig to start" there's something wrong with it, though - my
hotwire 3.5 is pretty good - it's slightly iffy at the moment but then it's
due a new set of plugs at this (or maybe the last :)) service.

leads are a good source of problems, if they're not in good condition.
Magnecor are worth the extra pennies, IMHO.

You could try using a second battery or a battery charger to supply a full
12V to the coil positive (the -ve goes to the engine block, not to the other
side of the coil!) - We used to have a motor which needed this treatment -
eventually found that the ignition switch was for some reason not supplying
full voltage/current, and that the voltage drop when cranking killed the
sparks.

doing that will eliminate any ignition-feed problems, including immobilisers
affecting the ignition.

have you tried towing it to bumpstart it?

Other things to check: cold start system (I think there is such a thing on
the hotwire...) for function; fuel system in general for correct settings.
Depending on age it may or may not be closed loop (i.e. lambda sensors in
the exhaust) and that could add problems; fuel lift pump for correct
operation and output - on mine, I had a fuel pump that went lazy - it still
ran and still pumped fuel, just not enough.
