68 Power Wagon - Won't start...
« on: January 18, 2005, 12:44:55 AM »
This is a friend's truck, so I'm gonna copy exactly what he told me...

1968 Power Wagon, 383/727...


It has: new ballast resistor, new points (gapped), new condenser, new rotor, new cap, new fuel pump, new fuel filter, new starter,fully charged batteries, new plugs gapped properly.

it will make good spark, but I'm thinking it's just not at the right time,  and how in the world you mess that up I don't know

I'm beginning to think that maybe it isn't just something simple like it always is

It turns over, and I think it fires once in a while, kinda a real weak fire though

good hot blue spark though

Pulled a carb off a running 68 383 Newport, put it on, and had same problem.

"

Then he mumbled about his other car's fuel pump going in the same weekend, and it being in the tank, and the pentastar gods being pissed at him. Any help please...

Yeah, you've checked the spark (intensity) the fuel sloshed into carb or a quick shot of starting fluid is a good next step.  Be careful with both of these... I have seen may  times where too much as added and it will wash the oil from the piston rings.  That means NO compression and NO start. (should that be the problem, remove all plugs, squirt oil into cylinders, crank engine, than reinstall plugs.)

With all the new items you listed in your post, my question is: were these done recently before the problem, or were these installed as a trial and error fashion to locate the problem?
Good Luck!

If it won't sputter/cough/try to start with gas poured down the carb, and the compression test comes back okay, I would suspect a timing issue.  Especially if he pulled the dist to swap the point & condenser.  Even if the dist wasn't pulled, replacing & regapping  points will change the base timing (some, not much).  It may have changed the timing enough to no longer want to start.  

If the dist was pulled, start from ground zero.  Bring #1 to TDC compression and re-stab the dist with the rotor pointing at #1 plug tower.  If the dist was not pulled, I would try bumping the dist either direction slightly.

1. Give us a history of the car around the time of this problem.
2. Before he put in the ballast resistor, points, etc etc . . did the engine run?
3. Why was he putting in all this stuff? Did he have some kind of problem? Or was he just doing a regular tuneup?
4. Did this problem happen very quickly? Under what circumstances?
5. Was the problem slow in developing? Gradually getting worse over several days, weeks?
5. How is the camshaft timing? Did he check that? Old timing chains skip, which will throw the valve timing and ignition timing off.

Are the spark plug wires installed in the proper firing order?
If you have no time to answer the questions or try the advice then don't expect to fix it anytime soon!

i have seen junk in the box condensors ,especially if you have weak/intermittent spark,also check lead to points inside distributor.the wire flexes constantly and can break.you can test point operation by checking at ign coil negative side with a test light clipped to positive on battery,it will flash while cranking.

Does it backfire or blow gas fumes up out of the carb? If so, you might have a bad timing chain.
