1984 Dodge Ramcharger Truck won't start after fixing distri

I recently bought the above vehicle and it ran decently. The truck needed a tune up and so my friend and I replaced all spark plugs, distributor cap, router, pcv valve, replaced all wires from spark plug to distributor cap and put on a new steering hose. We tripled checked the firing order is correct. Afterwards I tried to start the truck and it won't turn over. Any advice/suggestions.
Thanks,
Jon
