84 Dodge d150 cranks but want start. Checked full pump full filter. Changed coil distributor and rotary button. Still nothing. Help please

spark and fuel pressure need to be tested before replaced , does it have carburetor or TBI , what about the ballast resistor does it have one of them ,?

Yes it has carburetor. I am getting gas and the spark is good. I don't know what the ballast resistor is or where it is. I know there is a couple of small box's on driver side fender. And a ignition module on fire wall. I thought it might be ignition module but don't know how to check it

if you're getting spark at the plugs then it's not the module , if you pour some gas in the carb, does it start up ? look down the carb when it's off and open the throttle there should be a squirt of gas coming from the inner side of the throttle , only thing left is compression , fuel + spark + compression = vroom

Changed spark plug and wires. Still same changed ignegtion MOD it fired up

so you didn't have spark then
