does the dash all light up as normal and does the engine crank / turn over? as if not then its likely the immobilser is at fault

if it does crank and seem as normal then I'd investigate if you have 12V to the ignition module on the side of the distributor, if there's power here , then also check that you have a good engine earth connection with no corrosion and its tight at both ends

if thats all OK then I'd check inside the distributor cap to check the carbon brush that rubs against the rotor arm hasn't fallen out and if thats OK then replace the ignition module

this can be obtained from ignition specialists like

and I think your distributor is the Lucs 45D4 type - but check this
