Truck wont start
So first id like to say hello to everyone on the board as this is my first post.
I have a 66 f100 with a 390 4 on the floor with a granny low and 4:10 gears in the rear. picked it up about a month and a half ago for $800
Now on to my problem the other day i get home from work hop in the truck and head over to kragen to get some oil because the truck is leaking oil (looks like its out of the oil pan gasket) so i get to kragen buy some stuff and hop back in the truck. I put it in reverse backed out of my parking space and when i put it in gear the truck died. i tried starting it for a while but it would die every time i put it in gear then eventually turning the key wouldnt do anything. I removed the ignition switch from the dash and started jiggeling it around a little and the truck would start to crank and die depending on how i moved the switch. so i bought a new ignition switch and installed it. I tried starting the truck. the truck started but then died right away. Then trning the key would do nothing again. I recently replaced the starter solinoid but i decided to test it so i bypassed the solinoid with a piece of wire and the truck cranks but will not start. Anyone have any thoughts as to what the problem could be?

I smell gas from the carb when the truck cranks also wouldn't it atleast crank when I turn the ignition? Right now ever once and a while the ignition will crank the truck but for the most part turning the key does nothing and the ignition switch and starter solinoid are new

Ok jumped the wires and the truck starts and runs so looks like it's a wiring issue I guess maybe a connection came loose or something

Did you fiddle with the points at all???? It doesn't take much.
I have had my truck to just shut down, readjust the points and it fire back up. I don't run points any longer.

by. The time I got home it was dark so I only tried jumping those wires. The truck fired right up and stayed on didn't die or anything. I'm going to properly gap the points today when I get home and if that dosnt fix it I'll start looking for shorts or loos wiring in the ignition circuit.

So we've narrowed it down to the ignition circuit. Check for loose connections, but odds are it's the ignition switch.

If I have not already done so, Welcome to FTE, warehouse of knowledge and helpful members.
After checking wire harness and connections, if have not already done so, suggest a basic tune up; points, condensor, plugs, dizzy cap, rotor, relatively cheap and can eliminate from list of possible problems. Most importantly install a fuel filter as soon as possible. Installed a canister type on inner fender of 65 but any type filter will work. Purchased a cheap inline spark tester and remote start button from HF and able to perform a quick trouble shoot from under the hood.
Mentioned replacing the 'starter solinoid', curious if meant 'starter relay', sets on the passenger side inner fender, if connections and circuits look good, perhaps relay is defective, perhaps more knowledgeable member can advise. Finally, IMHO a wiring diag. manual, cost around $7.00 is a damn good investment, found it very helpful in tracing circuits and rewiring my 65.
Again, welcome to FTE.
