Did it run for a sec. Or two?When you say it tries does it fire, misfire, skip? Check fire pull wire hold 1/4 in. From block crank should be blue. If not weak coil.
Also look for Vaccum leak hose etc. Have someone crank spray carb cleaner around intake throttle if she comes to life briefly there is your vac. Leak

When I changed the fuel filter I noticed what looked like twin fuel pumps would this be correct and if so if 1 went faulty could this result in poor fuel delivery ie not starting

Not like that high resistance in the plug wiring may cause but lots of miles is usually what does it.

Getting good fuel pressure upto the fuel distributor but doesnt seem to be injecting fuel to the cylinders plugs are dry after cranking over for a few minutes.
What actually gives the pressure in the fuel distributor so as I can get a better understanding of how it works
