Won't start now

I took the engine out of my 68 F-150 to paint it put it back in my truck hooked everything back up now it won't start. I can't seem to figure this out looking for ideas. Can anyone help please?

Does it crank at all?
Also, make sure the fat pink wire is hooked to the coil + side, and not to a sensor.

Unhappy help please

I don't know if you can give me a hand with this but here it goes. I removed the 390 from my 68 F-100 to paint it and change the input transmission seal. Now everything is back together (looks great) but I can't get it to start. It turns over strong sounds like it is trying to fire up when I let off the key it stops like I wasn't trying to start it in the first place. As far as I can tell I haven't burnt any wires. The ballast resister is testing good, it has voltage at the positive side of the coil, and spark. I been messing with this for about a week and I'm starting to pull out my hair. Help please if you can.

From: in the springs
my best advice would be to set the engine to tdc #1 take all the wires off pop the cap make sure the rotor is pointing to a contact, if so wire it up from that point (dont get hung up on wether it is in the location it shows in the book), if not adjust the dizzy housing till the rotor is pointing to a contact point. at this point dont assume anything is correct because it was before. take it from some body who has learned th hard way. (just cuz the truck had half a tank of gas when you pulled the motor doesnt mean there is still any in the tank to crank your new motor with.)

I found a crack in the fuel pump, changed it. Now we have gas and still didn't want to start so I hot wired the coil and decided it has a bad ignition switch

Ok I changed the ignition switch and the ballast resister still won't start, if I take the resister it starts right up. Will this hurt anything if I run the truck without the resister?

Yes, running an ignition that requires a ballast resistor without it, will burn up your points(or module/coil on an electronic ignition).

This truck had a ballast resister in it when I got almost 7 years ago I've been running the petronics electronic ignition for about 6 months with the resister in. That is why I am so confused on why it won't start now I didn't change the set up of anything electrical.

The Ford distributor uses a resisted 12 Voltage down to 8V after engine start .

The Pertronix ignition should have 12 Volts hooked to the coil.

What brand & Model of coil do you have ?
