I just got my 390 back into my 1973 F250 Highboy i went to start it and turned the key once and the radio, lights and everything else worked i turned it once more to start it and nothing happened i checked all the wiring and i cant seem to find anything. Has this happened to any of you or do you have any suggestions on how to fix this problem for the time being i have been crossing the terminals on the starter solenoid but thats getting old really quick, Help would be really nice, thanks.

Have a look at the suggestions about what things will power up.
We need a check list of what you have done.
Battery charged ?
Cables Clean ?
Do you have headlights, heater fan, wipers, Turn signals
Is the Starter Solenoid working properly when By-passing the switch?

In order to get the starter to turn over the engine with the ignition switch you need:
a) 12 volts to the ignition switch on the large yellow wire battery hooked up
b) 12 volts out of the ignition switch on the red/blue striped wire when switch turned to start
c) 12 volts into the neutral safety switch on the red/blue striped wire when key to start
d) 12 volts out of the neutral safety switch on the other red/blue striped wire when tranny is in park or neutral and key to start
e) 12 volts to the wire on the "S" terminal of the starter relay also red/blue striped when tranny is in park or neutral and key to start
f) a good clean ground under the starter relay mount plate and bolts
g) a good starter relay, this can be checked by jumping 12 volts to the "S" terminal. If starter turns relay is good. Also note it wont work if the ground for the relay mount is no good.
If it is a manual tranny there is no neutral safety switch, just a jumper wire.... big surprise it is red/blue striped
Located just inside the engine compartment on the drivers side where all the wires come thru the firewall.
Good Luck.
