1972 Ford F250 running

When its warm and wont start, remove the top of the air cleaner, open the choke and have someone try to start it. Get back with the result. Give it 2-3 pumps on the gas and hold pedal down to the floor and choke wide open when cranking.

it still jus turns over seems like no spark but it has all new electrical stuff under hood like coil plugs solinoid starter battery and points

Start with the basics, and work your way up, Last tune up was? Wires plugs ALL filters? If all that is ok, check for a stuck EGR, then test fuel pump pressure, If it won't restart, determine what's missing, the engine needs three things to run, Spark at all plugs, gas to all cylinders, and compression in all cylinders, tho an engine may run lacking one in one cylinder, it won't run very well! Post the answer to whats missing then we can figure out the next step.
