Your question is the sign of bad crank sensor,you have fire and fuel,but the crank sensor tell,s the ECM when to fire and has to be in time,if bad won,t know when to fire or give fuel correctly.

No start, dies while driving, intermittent engine misfire. But yours will not crank over, so look for an open circuit in the main power supply and grounds to the starter, if that checks good then check for power to the key cranking power side of the starter solenoid, if you have all of this then the starter is most likely the problem, unless the engine is totally seized. Then you have problems.

It gets fire from the coil to the distributer. It's not getting any fire from the distributer capvto the plugs. Does that make sense?

Yep the cap is either carbon tracked, or the rotor is burned through, I would replace then both if it has never been done.
