Your starter relay is upside down. It will work that way but if the spring inside ever breaks or gets weak it will make contact and run the starter. A sharp bump in the road may even be enough.

I freaking love this truck so much. That engine, and the fact it’s stick shift just make this truck so awesome imo

Everything happens for a reason, Craig. You probably just saved someone's life. We are learning so much from you. Thanks

I 100% agree with your everything happens for a reason statement Craig, cause 2 months ago my leaf spring shackle snapped in my truck and I was gonna drive it to work anyways on the loose leaf spring, but my truck kept stalling out when it in drive, and as soon as I fixed the shackle never had that stalling issue again, I truly believe that the world looks out for us so that we don't endanger ourselves or others.

With a pump that big I would run a return line, those deadhead regulators get really wonky with a big pump, swapped over one with a return and have had zero issues with fuel pressure

It’s good to see the sickest f100 on KZfaq back on the streets!

Everything happens for a reason. When I was young and stupid I was hit about 120mph in my ‘70 Monte Carlo- my buddy was in his Camaro- backed off. Three days later I was just cruising at about 30mph when my drivers side A-arm snapped in half and about took me into the guardrail. Three days earlier and I’d be dead.

Thank God you posted this video. I've been looking for a good explanation on this forever. This is exactly what happened to my truck before I bought it. The resistor wire completely melted through the whole harness and created havoc. All of you just getting into Ford trucks pay attention!!! And check that little 4 pin plug if you have electronic ignition make the change!!!

Super helpful info in this video man! I have a 69 f100 that I’m 351 Windsor swapping so I’m just soaking all this up! Don’t get down bro, you’ll never regret doing things right!

God this thing sounds angelic. Nothing like it. Thanks for the (very) short ride! From all things, i‘m glad it was ‘just’ the starter that broke!

Hi Craig, the wire is not connected to a resistor, the wire IS the resistor and it is soft and rubbery from new. Nice electrical distribution box 👌

Rotate starter relay 180 degrees. Ensure it is grounded properly to the inner fender. You could get an original Ford/Motorcraft relay from a junkyard and test that to see if it works better than the one you have now. I just gotta say your truck sounds like a Formula 1 race car and a dragster combined! Dam, that IS a bad ass F-100 !!!!!!!

Dang good Craig, just a suggestion. Back in the 90's my 69' Fairlane 289 popped the distributor on the way home from work. Dual points system. That weekend me and my dad wired the complete ignition system from my wrecked 83' f100, 302. Never had a lick of trouble after that and improved fuel mileage.

You know I'm 58 years old, and have been assembling motors since I was 18 not including motorcycle engines I have assembled a few dozen engines for friends, and friends of friends. I then got into racing motorcycles, and assembling engines to the point I have done a couple dozen of them including a few Harley sportster and big twin engines. I say I have assembled engines because I don't do machine work, and that is the most important part of building a engine, then comes assembly to complete the engine. The third most important thing in the life of a engine is treatment. I impress that on everyone I did a engine for. First take your time and put some gentle miles on your new engine around 1100 to be exact the first miles are important as you need to make sure the engine is tuned right or a little rich, a little light on timing, the first 50 miles you should not cold rev or no load rev the engine, on the first long drives on a highway vary the speed of the engine a lot. at about 250 miles we power tune at a drag strip (MPH = HP) then you do what you want. I know you are going to make fun of this post Craig but I have yet to have any engine I assemble, and tune blow up in the first two years after being installed in the vehical, and you have blown up the same engine four times in one year. If I had a dollar for every year a engine assembled ran with out a failure in my life time I could build another hot rod. Craig if you got a dollar for every year a engine ran that you assembled I honestly think you couldn't buy a Happy Meal at McDonalds with the proceeds. Laugh that one off big boy. I also had a 76 ford truck with a .010 over 390, 10 to1 compresion, comp cams H280 hydrolic non roller cam, 66 GT390 heads and intake (both mildly ported) Headers, MSD 6al box, Holley 700 double pumper, stock bottom end all but pistons. This engine was spare parts thrown together combo made just shy of 400 whp, and ran under me towing my trailer, running for parts, and doing long assed smokey burnouts under my care for eight years until I sold the truck to buy a newer truck because I was starting a family. Quit being a tool, spend more time trying to figure out why your junk blows up instead of just throwing money at the problem, Spend less time on the internet and more time reading older books on race engine building. Knowing the nick names for all the ford body styles you can never make run very long makes you look like a dip shit. So spend your time reading really important infomation. Sorry this got so long and a little out of hand, but I hope it shows the difference between a mechanic and a KZfaqr. A mechanic cares about fixing what is broken or slow, a youtuber learns unusablle facts, and looks like a dipshit to get subscribers, and writen coments. A true craftsman is rewarded in cash payments, and the satisfaction his stuff dose what it is supose to do.

Gorgeous truck and build. That sound 😮‍💨. With all of the attention to detail, look into a rivnut kit instead of the self tappers. Would be the icing on the cake!

Beauty job on the wring Craig. Im 43 and still learning sh!t about my truck everytime i rebuild something. That truck is a beaut

It looks like the junction connector(the black connector) finally failed. The wire that connects to the junction connector and then runs to the ignition coil is a resistance wire. It is designed to reduce the voltage and amperage that runs through the ignition points so the points don't burn up. If you install a modern 12V ignition system you need to replace the resistor wire to insure you have maximum voltage and amperage to the coil. GM also uses a resistor wire. Chrysler used a resistor block.

Thanks for the heads up on the resistor wire. Someone had already done away with the points and done the swap on mine. Now I need to go look for that issue

The F100 does sound great Craig. That starter problem is unbelievable. I know that you will get it sorted out. Thanks for sharing. 👍 👍

Yeah man, never change those slicks, maybe some drag radials, but those slicks really make the truck look amazing.

My factory wiring harness was a rats nest in my 66f100, I bought a American Autowire kit and i completely re-ran every wire in my truck how I wanted it and it is amazing! highly recommend the company if you every rewire your vehicles. It comes with everything you need and even an updated fuse block.

Great job this far on the new build , just take your time and dont hurry on finishing the truck . Work out all the issues before you rip on it and take it for a longer drive.

Im running a powermaster high torque starter in my 10.4.1 compression 351 works great

The relay panels, power distribution panels, and various underhood electrical control panels are well thought out and work logically -- well done!! It was a good omen that you found that melted/damaged factory wiring before it became an on road disaster. Can you electronically control and monitor the A-F-Ratio ? That would ensure the engine never runs lean again.

Thing sounds wicked! Time for me to revisit my exhaust 😉

I absolutely love your truck Craig been a fan since 2018 keep up the amazing content I love

lots of frustration but...ran into that same fusable wire problem on a chevy truck total pain.. best to make your own harness or buy one from painless wiring harnesses. love your truck and thanks for the info on Derale electric fans/shroud

Take your time is solid advice

Glad the F100 is back! Lets go!!!!

Love watching these f100 video's. However I believe you mentioned putting a AFR gauge on it before ripping it again.

Now get you some front and rear anti sway bars , I am running on my 78 flairside 1-1/8 front and 7/8 rear with nitro-charged shocks , handles like a sports car !!!

I did a 21 circuit from kwik wire in my 76 f250, love that harness

great stuff thanks

Dude i really needed to hear that im literally to point giving up on my obs but u motivate me to keep going 🤝🏼 keep up the good work bro and keep booming im a og sub from when i saw ur 1st video open headers in high school

Awesome sounding great.

Craig love truck bro you make me soooo excited to get my first project car. Can’t wait to see you take your baby to a show keep up the work. And I just comped a small block killer tee can’t wait for it to arrive

Sounds so rad!!!

Love the videos I’ve watch almost all of them. I’m looking at a 85 dodge d150 it is somewhat primed and the other parts are patina can’t wait to go look at it when

it sounds so good!

Sounds SICK!!! #BuiltByBo

Starter solenoid is upside down homie

I know there's not a lot of room in that compared to modern trucks but, considering how and where you drive this, I'd want to try and fit high-back buckets and proper harnesses. Safety squints don't help much for unintended off-road excursions.

Got to watch them fusible links, Ford liked to put them in a lot of cars and trucks, your fox has them in it too. Don’t know why they just didn’t use fuses, or circuit breakers. I guess a cheap piece of wire made to catch on fire easily and burn up quickly was cheaper than fuses 😂

Nice job on the wiring!

Hey I like using those cheap "crappy" brass fittings 😅 they will last as long as any AN fitting and if done right looks just as good in my opinion. Which im more concerned with what works and what will make power and go fast than looks anyway because looks doesnt make power or will get ya home anyway. But your truck does sound gnarly as hell and should run pretty quick with around 400 rwhp . That nascar wheel setup looks badass as hell. Gives it the perfect stance 🤟😁

I did a painless kit in my 68. As soon as i got it home. The truck ran great. But the harnesses all cut and cobled together. It was not something that is a quick job. Good luck

Yup pay attention when divine intervention of 8 different flavors pulls up it definitely means something... also im glad u stopped it before the whole truck got lit on fire

Love the videos!

Dude, I’m sitting here watching your videos. I’ve got an old 73 Ford Torino 351 Cleveland but it’s pretty much just 30 over nothing radical like your pick up. If I had that pick up, if I were you, I would go to the Hollie EFI that way you’re not tuning the richness and leaning of the engine, the old race car way by just checking the plugs you are then setting it precisely with software. That way it will never lean out again

11:22 yeah I have the same thoughts right now

Such a sick truck

That is some trick wiring🤟🤟🤟

Excellent work Craig. you’re a great mechanic, and I love your videos. So glad I subscribe to your channel.🔧⚒️🔩🔨👍👏👏🍻🍻🍻 Mike from Florida

For what it’s worth I’ve ran painless kits before that you mentioned about swapping to at some point and in my experience now I’m changing over to American auto wires kits, not only are they easier but I’ve found them to be just a flat out higher quality, are they cheap no but have they been flawless out of the 4 kits I’ve done now… yes they have been 100% perfect every time and their customer service is amazing as well so whether this is helpful or not thought I would add my experience

Where is the other Truck frame with the crown Vic swap and stuff !? 😮

Really cool build

Love the Trukk

i prefer to "nail" the fan directly to the radiator. That way you dont need a shroud because the narrow fan "housing" is the shroud. AND you get much better cooling while driving.

Frick that thing sounds nasty! It's like a late 90's cup car! I can't wait to see you really rip on it

Put u some amsoil dominator or vrod in that bad boy. Did it my gto and love it!! 😬

Hello Craig! I was wondering if you had the rear package tray for 64 Galaxie 500xl with the double hump. I been looking for with no luck. Thanks

Man it sounds good

Man, she sounds freaking rad!

I’ve had this happen in my obs ford with a 351w. I’ll start it and then it’ll keep trying to start. And when I turn the key off it keeps trying to start.

I hope soon we get a vid of all the vehicles you have

Dang Craig, been bitin the bullet a lot this past few weeks huh? Eh you'll get it.

Your solenoid is upside down. You need to mount it the other way up. That’s the reason the starter was stuck on.

Craig shouldn't the fuse block with 4 relays be mounted in side firewall?

That 302 sounds wicked good.

The main wire going to the distribution box you made looks very small for the amount of power that can possibly go through it.

Sounds great but dang U hammer on it so much

Actually For older vehicles fan shrouds are not needed.( Depending on the motor build). Back then, manufactures didn't actually sell all vehicles with fan shrouds, the only vehicles that got them were "desert vehicles". Which people custom ordered if they lived in a very hot place. But my 71 F100 has a rebuilt 352 Big Block that's been bored and stroked to 410, its runs great without a fan shroud, doesn't over heat. Not saying for all vehicles fan shrouds aren't needed, just saying that some vehicles don't need them.

Nothing like watching a fresh F100 video while wearing my new small block killer shirt!

Ive been fighting my chopped up wiring harness for weeks and finally broke down and ordered a painless harness.

Why do you have the old vacuum canister still connected inside the passenger side front frame?

One thing a small block Ford suffers from is heat soak .Got to keep it cool..Around 165 degrees is great..190 degrees...no

DUDE!! Great content and vehicles.. But watching this vid and seeing the coil youvrun on the truck is kinda sad. You gotta upgrade that overheating oil filled weak coil.

Keep pickin at it, you'll get the bugs worked out of it.

HEY CRAIG! Could you give me part numbers for the radiator, fan and shroud? I've been looking for a setup for my f250 that also runs an electric pump. Would really appreciate it.

Those solenoids suck, I bought one of the nicer ones and it was 60 bucks, and it burned up and made the starter run exactly like yours. We ended up getting rid of that solenoid. I forget how we did it, but it was for a demoliition derby car, so it we didn't need any of the safetys or anything and it works perfect. Our starter also had its own solenoid connected to it so we ran it off of that with a bridge.

I had the same thing happened to me. And I had to replace the key switch and. Starter

What did you do to the suspension? I want to lower my truck a little but not to much

Part numbers for the shroud, fans and controller please.

Which video shows u doing the wiring panel

Did you sell the Galaxies? I really wanted to see them finished. If you have them did you lose interest in finishing them or at least one the red one.

When did you get rid of the mercury switch on the hood?

I hope the gallaxys are next

Sweet been waiting lol

😂😂😂LMAO!!! If it were not for bad luck, you would not have any luck at all. LOL, I feel your pain. I've been there too many times. Hang in there it's coming together.

Your exactly right I had to bypass mine

Take u time

where did you get the headliner?

Need to know the tire and rims dimensions asap looking to order for my silverado this week well because....nastruck lol please let me no

Man your the definition of hard work awesome progress

Does this truck still have the tr3550 5 speed?

I laughed so hard when you caught yourself on butt plugs 😂. The response was the funny part…

You need vented valve covers or a vacuum pump

Have you ever considered trying to supercharge it?

What happened to the mullet? It's about time ya got rid of that!

Well in a truck under the hood there’s lots of room for activities 😊
