I'm a new member and find this a great site! My 76 F150 has a problem that has me stumpped. When the key is turned to "start" the engine turns over very strong and will continue to do so but will not fire till I relaese the key then it will start. I checked for fire at the plugs and have none while cranking but the second you release the key it will fire and start. I have a new Ign. box,cap and rotor. Could it be in the ign. switch? Again great site thanks, Cliff.

With the key in the RUN position go to the battery + post and use a wire to contact the S terminal of the solenoid to see if the starter turns over and the engine starts up.
(Horshack's arm shoots up) Ooo! OOOOoooooo! Ooo! Ooo! OOOOooooOOoOoOo! I KNOW this one. Gold plated guarantee. The ignition box. Mounted to the driver's side inner fender. Has 2 circuits in it. The start circuit has died. The run circuit is still good. Had this exact same thing happen on my dad's 76. Napa has the box for around $30. 3 screws and 2 plugs. 15 minute job and your golden again.
Write it down, take it to the bank and tell 'em I told you so!!
