74 dart has electrical power but no start
OK, let's not start with the old "let's throw parts at it and hope."
You need to look at the posted diagram, bad as it is, or get a better one.
One the top diagram, look for the starter relay, right below and left of the starter.
Notice the two terminals on the right side of the relay, marked L and G in this diagram. THESE ARE the coil of the relay, and can be switched. Thes are the two "push on terminals"
The wire heading off "L" and going down, goes through the bulkhead to the "start" contact on the ignition switch.
THIS WIRE which should be yellow or yellow with tracer is the "hot" wire "in start" from the key
You need to find it, check it with the ign switch twisted to start, and see if it's hot. IF not, trace it back to the bulkhead connector, and see if it's hot THERE. If not, I'd pull the bulkhead connector apart, and then check the half that's in the firewall.
IF THIS IS NOT HOT, the only thing you have from the firewall connector is a short length of wire to the igniton switch.
So now you are looking at this wire, or the connector being loose/ bad on the ignition switch, or a bad switch itself.
BUT -- if you find this yellow and it's hot "in start", NOW you have to look at the GROUND side of the relay.
IF you have a stick transmission, the SECOND push on terminal goes to the clutch safety switch and GROUNDS that second terminal when the clutch is depressed
IF you have an automatic transmission, the SECOND push on terminal goes to the center pin of the transmission switch (neutral safety) and once again, GROUNDS the second terminal when in neutral or park
So your starter relay COIL path is from IGN SWITCH to BULKHEAD CONNECTOR to START RELAY PUSH ON TERMINAL --through the coil -- FROM SECOND PUSH ON TERMINAL to GROUND (through NEUTRAL SAFETY or CLUTCH SAFETY switch)
THE ABOVE turns on the STARTER RELAY
The two contacts (switch) of the STARTER RELAY are the great big stud which is hooked to the battery, and the "square" terminal which goes to the starter solenoid.
The only other screw in this deal is "do you" or "did you" have the incredibly irritating seat belt interlock?
If you do, it's a relay under the hood with a great big reset button on top

If you do, there should be two yellow or yellow with tracer wires to the plug. Connect these two together
