That's a bitch.

So I've headed a different direction and bought an MSD street fire ready to run dist 1 -12v wire plugs into the battery terminal on the cap. I have good power on that pink wire it reads 12.25 V . Will just not having the ESC plugged into anything basically disable it . Thanks for everyone's patience and assistance .

You have to take them out on a date and make them feel appreciated to rekindle the spark... Deleting the ESC and using an older distributor should solve your issue, if not unless you run a new hot wire to your msd stuff you may still end up in the same situation just $3-$900 poorer... get it running before adding more parts.

Make sure you are on the compression stroke when you check #1

Cylinder. Pull #1 spark plug and turn engine over slowly till you
Feel your finger get push d away hard. Slowly rotate engine to
O on the timing tab. Stop. Now pull dizzy cap and make sure the
Rotor is pointing to #1 plug wire. After it starts , reset timing.

Update truck is now running good just needs a little fine tuning . ESC system removed in its entirety . completed the smog removal except the efe valve on the exhaust left vacuum hooked up to that . New MSD street fire hei dist . Had some struggles with the dist being a tooth off . It is shifting a little hard so I'm thinking I need to adjust the TV cable . A little more tuning on the timing and carb . Next will be headers and exhaust . Then cam and lifters and eventually some new heads . Thanks for everyone's input .

Glad you got her going. Also glad to see you keep the thread updated after finding the problem. Far too many people come looking for solutions, and once they find it, they just drop the thread leaving everyone hanging wondering whether they fixed it or what fixed it.

Be sure to get that TV cable adjusted right or it's highly possible you could hurt the transmission. Glad to hear it's running. That MSD ignition should be of good quality and very reliable in HEI form.

Hey, Im going to bring this one back from being luke warm, not yet dead.

I have been fighting the problem where I thought that it was a fuel issue. But last night I know for sure was a spark issue. Im leading to the ICM now. Long story short, in the middle of trying to figure out every single problem with the truck, I got a Chineseium A-Team dist from Amazon.

Truck in 95+ degrees Texas heat and about 45 minutes of driving it seemed to run lean and die. I thought that fuel pressure wasnt enough (gauge read low) and that maybe fuel boil. Cooled down for about 1.5-2 hours and start right back up. Last night it died but I had 5 psi and I could see and smell the carb shooting fuel.

Are we in agreeance that I should just get an AC Delco one or is there a brand that you like better?

Been running ACDelcos' in 8 different vehicles & engines for 50 years. Tried fancy ones and multi-tip ones. They never lasted long.

No complaints with ACDs' here. Always got good MPG.

NGK all the way

For the module? Absolutely. The trick is making sure you clean off the old heat sink compound off the distributor, and I use two tubes of it. One for the module, one for the distributor. My aftermarket TBI ignition module that the PO put on failed, blew my ECM-I fuse, and friend an injector. That shouldn’t happen so I wouldn’t trust anything else other than to escape an emergency breakdown.

 

[Rusty Nail]

I've never heard of anything so ridiculous! What kind of aftermarket module?
Actually I used an old MSD module once that fried my COIL, but not the module....

 

[Snoots]

This is great for ignition modules:

There is another called SilverIce but it's $45 per tube (little tube).

Delco modules are the only ones that seem to last.. I have several in my tool box that I grabbed from a junkyard as spares. Are you sure its not the coil? It would do the same thing and they get weak when they get hot.

I second checking the ignition coil before you start tearing stuff apart.
