Johnny's 68 Formula S

To re and re your gas tank is one of the easiest things you will do on your car. My only advice is to make sure your sending unit lock ring is good and applies adequate pressure to make a good seal. I put a little gas in my tank and tilted it back to check for leaks at the sending unit BEFORE putting it back in my car.
 
That could be what killed your ecm. Get FACTORY correct schematics.
Go to mymopar.com lots of freebies there.
My ecm died from natural causes, they sent a New one and it seems fine.
well i think the cuprit was the positive cable running threw the fire wall to the trunk!
The numskull drilled a hole and just put the cable threw i almost fried my car.
thanks goodness for quick dissconect.
Now i need a battery tray and a positive cable to put it back up front where it should be.
between the new freeze out plug leak, the fuel issues. I dont know after almost frying the car id like to abort this project.
you might find it in the classified section soon.

Electrical is voodoo to me, but "natural causes" for an ecm to die? And now the alternator doesnt charge?
These are a "system" and something may last a while and then cause issues down the road. Make sure you are documenting every single change that you are making from factory. Some real sharp elec gurus on here that can help.
Good luck.
Oh not being a smartass, BUT get a fire extinguisher asap to keep in car. I have one.

The ecm must have just been a bad one, I have read that they are not made well lately.
It died immediately on install & first 1/2 mile drive, So the company sent me a new one and was charging fine until the positive cable was arching,

If you have one freeze plug leaking, the rest are going to leak. Buying a 51 year old vehicle that you have no personal history of is invariably going to present issues of someone elses tastes and finger f##kin'. Slow down, take a breather.

i'm trying, i'm trying i have no patience!
 
Someone on here sells the cables, forget who. Someone may speak up.
yeah i think one of the members sells them close to $175 Geez nothing is cheap lol wanna play Gotta pay
 
Get a "normal " cable for now, never mind the millionaire ****. Get it running driving reliably. Then make "upgrades". We have a rare 69 cuda and the damned thing hasnt seen the road since I bought it over 30 years ago. #'s matching bs is $$ and overrated.

Tank, Sender and New straps going in.
 

Holy smokes, that is some fantastic documentation! Very special car. Dont let a few minor setbacks make you want to sell the car. We have all be frustrated just like you. Removing the headers for the second or 3rd time is super irritating but you may think about possibly pulling the engine to regasket it since you are already needing to hang new freeze plugs , especially in the back ? Make sure to coat the bore holes in PTFE sealer before you put the plugs in. I had to learn this the hard way in my powerwagon 360 but now could probably pull one of those engines in my sleep due to multiple times fixing newly installed freeze plugs.
