I feel your pain, it is two darn hot here in the armpit of Texas. You have thrown a lot at this problem. Check the wires carefully with a continuity tester from point A to B. I had a similar instance and it was one of the wires to the coil that had been pinched and was broken internally. It was intermittent. I missed it because it did not show any outward symptoms of being broke. I found it with the tester. It sucked because I traced and tested the majority of the harness before I found it. Double check all wiring you have corrected also. Keep at it, patience and perseverance will win.

Yep, that was some of the first testing we did was continuity of the existing wires, and all tested good, but thinking problem is the ground side of the coil connection or distributor....which is next to trouble shoot.

If you read through much here, we took out the MSD and went back to new ICM, ICM harness, Coil. Also replaced the start switch under the dash, and checked everything front back sideways up down......

We will lick this for sure, as once we can get the engine to run, everything else can move forward with purpose

I saw that you went back to stock. I have not had any luck with the MSD boxes. We had one in a K5 blazer build that gave us nothing but grief. Good you are going through it with a fine tooth comb. you will get it figured out.

I am dying to know if you were able to get your guy to spin up! Were you able to find a dizzy or pickup and try it out?

Not spinning up yet.

Did get another distributor from 78 WideTrac (thanks so much), but temps here 105*+ right now, and just don't feel like I want to work out in it.

When it is 100* at 8 am, just takes the wind out of the sails quick.

Will get back at it one of these weekends again, and post results how that goes.....as we will overcome this issue

Wait, devildog, who's trying to sell your truck on BaT?!

I know, no lift or anything fancy like that on this one

You hit the nail on the head with that one.

No price as yet but the body & interior (excluding that gaudy electronic screen attached to the face of the dash....UGH) sure could just go on my frame

Wonder what it will sell for, as I do not track BAT site, but curious to know when it happens.

I'm with you there.

Fix up our old trucks, to be nice old trucks, but leave the electronics to the new junk!

Exactly! I don't mind some upgrades, and if the electronics are legit better then sobeit, but I'm NOT okay with driving an entertainment system on wheels. That's why I'm not big on most cars post-00s era.

A thought on fuel range in my FSJ



I read a lot about folks trying to get more range out of their FSJ's, by adding the "K-5 Blazer" 31 gl fuel tank between the frame, where the spare tire was designed to ride.



As it looks we need to run a second fill spout, and then to plumb the lines so it can draw from both tanks.



Idea.......



Add the second tank, instead of drawing directly out of that tank to run, what if I simply install an electric transfer pump in that second tank? And a fuel gauge of course!



When my primary tank gets low, I could hit the switch and transfer gas into my OEM tank?

I would think that would work. I haven't really dealt with duals before though; when the '88 got an S10 tank in the back, it all-out replaced the stock tank, so I don't know about tying them together or anything.

You know, if you went with fuel injection of some sort, you could run electric pumps in BOTH tanks

Now there ya go cussin again, saying those FI words!

Carb is the nice word

And not a fuel pump for engine use, just to transfer from reserve to main tank.

Same as a pickup with a service tank in the bed.

Say I have 20 useable gallons OEM tank, and 30 in reserve tank.....if I average a road trip @ 14 mpg....thats 700 mile range.

Light trail off road use, the reserve can be set up to put gas in my own rig, or into other rigs with an external hose.

Must be the farmer/rancher upbringing coming through me again

Overdrive - bolt on

Thought is for general information as I had the thought to find one for my rig.

Overdrive unit available (for hiway OD only-which is what I want) bolts on back of the existing TC, requires a new rear only drive shaft, and turns the 727 3-speed into a 6-speed.

The bolt on unit electronically shifts in manual or auto shift mode with 1/2 gear increments, to the full gear shift of the auto trans.

So your 3-speed will shift like this
1 to 1-1/2 to 2 to 2-1/2 to 3 to 3-1/2

This is the site for Dodge 727 3-speed info
Dodge 3-Speed Auto - Gearvendors

Go here for more info-
info@gearvendors.com

Looks like the bolt on unit is right at $3200, then need shorter rear drive shaft, as unit is about 12" thick.

Best part about it, they have an exchange program so when you change vehicles, you get credit for exchange to different unit.

Units handle up to 1200 hp, then need hydraulic modification up to 2000 hp.

Looks promising....just need to find those money tree seeds and get that sucker growing

Honestly....would rather spend this kind of money for an O/D unit, rather than FI.

Cussing? AGAIN? When was the first time?

You're willing to fill up other rigs? If you're not making them pay more for it than you did (I mean, they're the ones who ran out of gas in the middle of nowhere), you are nicer than I am. Unless it's your own rig

14 may not be reasonable for a carb on a 401, especially with big tires and 4" of lift, and at this point no O/D. The 3.31s will help but not significantly enough to make up for all of that. I'd expect a solid 12 probably. But who knows?

Not feeding anyone for free, as there are ways to pay for stuff now, as long as you have a cell signal.

Thinking more just enough to limp back to the pump, so nobody is stranded

Not going with the "big" tires, as they serve me no purpose, so the 31's IF I do go with them, would be as big as they would get.

Thinking more of stock all season LT tires, so keeping the torque values on the tires, and not on horsepower.

I like the LT tire route. I am not going to lift mine for now and will probably go with AT tires.

Yep....as my rig I want to build mostly for road use pulling our camper and light trail use.

I want tread that will get more comfort miles traveling from home and back, but with a little off road grip, than airing up & down for serious off road traction.

The LT are moderate grip, and higher plies for load.

I have a CJ5 for the crazy off road stuff

Agree!

My 401 got 8 mpg with 33s and 3.54s.
Checked and rechecked this many times.
The Gas Pig is what I called it.

PITA as it is super hard to get the dam thing to take fuel.. which is required ALL too regularly !!

I won't mention how I fixed this . . .

Be cautious with adding an OD unit. Your drivability may suffer greatly.
Gearing is important for balance drivetrain performance.
Will load the trans more, which can result in heating the fluid.
Heat is the enemy of trans longevity.
