I have 73 ford 3/4 ton with a brand new battery, starter , and solenoid and when I turn the key, I get absolutely nothing, not even a click. So, I cross the solenoid and make it do the work, it starts right up. So, I know it has to be electrical, because while the truck happened to be running, I needed to move it a little, I turned on the defrost, just messing around, and my truck died. So I cross the solenoid again, and tried it again, and the truck died. I need help trying to figure out where to start and how to look for this issue.

hey johnny it's definitely your starter relay it's locked inside and is sending power from the battery directly through the relay from one cable to the other straight to the battery that's why it continues to keep starting this happened to me and the starter motor just kept turning and my truck would not shut off
this is it it's on the fender or right next to the battery change it there about $15-20 bucks good luck Stephen and trust me this is it
I'm probably stating the obvious but I presume you've cleaned and checked all the wire connections. If you haven't yet done so, it might be a good time to install the hot-start relay kit that AutoAtlanta sells for these cars. That may solve the problem and will prevent the future non-starts when the engine is hot. Also, ask the same question on the 914 Club or World forum and you'll get some real expert advice.
Hi! It sounds like a bad solenoid, or that you're not getting the 12 volts to the solenoid to engage the heavy amperage needed to turn thr starter motor. When you say you bypass it,do you mean you are just crossing the large post of the solenoid with the battery cable connection at the starter? When you turn the key,you should get 12 volts at least at the smaller post on the solenoid.If you have 12 volts there when the key is all the way to `start 'position,then the starter probably ought to be replaced. This car being a 2000 is 13 yrs.old.Won't hurt to put a new starter on it. don-ohio (:^)
It sounds like a fault in the starter circuit. It could be a defective neutral safety switch, starter solenoid, or possible a defective ignition switch but I doubt it. Can you hear the starter solenoid??? I'm willing to bet the problem is either with starter relay, neutral safety switch, or starter solenoid.
The starter is turning only when the solenoid close the contact to deliver the current to the starter . When this happens it then turns the bendix to engage with the flying wheel to start the engine.
The reason that you need higher voltage to have correct needed current going through the contact of the solenoid, hence the starter. The contact is corroded or rusty due to high spark at high current at every start time causing high resistance. V=IR the R resistance of the contact now is high so it need higher voltage (14.3 vs, 12.8 V) to deliver the same needed current for the starter.
Unfortunately, the solenoid is integrated with the starter, so you can not just replace the solenoid without replacing the starter.
If you can find the new battery holding at 14.3 V as you mentioned, then that is an economical solution since replacing the starter is costing more.
BTW where can I find the battery at 14.3V in case my friend's car has a same problem?
Does the truck turn over but won’t start? If so there is a fusible link running from the starter solenoid behind the battery.
Also if you get nothing when you turn the key could be the solenoid. Its easy enough to jump the solenoid and check . Check all the fusible links coming off the power side of the solenoid and replace as needed.
if car is automatic, try starting in 'N" , locate starter motor and tap it hard wile turning key to start, if cr starts after, needs new starter, look if lights and instruments come on when turning key, try to start car from starter, also key problem
