so heres the deal, no matter where the distributer there is no fire. i bought a new coil and i see spark to the plugs but it looks weak. the carb is messed up and i dont know where to put the needle valve. i was told 1.75 out but its 2.0 out now and the plugs look really dry. help please!!!
im out of ideas

I don't remember the specifics of the original LUV ditributer, so here's some basic troubleshooting steps for weak spark:
1) Check the plug gap, make sure it is correct for the application
2) Do those have points? Check point gap and condition of points.
3) Set base timing. Position cyl. 1 at TDC, and then set the dist. in place for that.
4) If you are still seeing a weak spark, test the resisiteance of the plug and coil wires - if there's an issue with the wires, it'll hamper spark.
5) Once you get the base timing close, try getting it to fire with a can of starter fluid.

If you can get it to fire up with starter fluid, then you might have better luck determining what the fueling problem is. But the first problem to solve is getting it to run on it's own fire...

Hope that helps...

You might also check your fuseable links...they will be the two wires coming off of you battery...then check all your ignition-related wiring.

Figure out whether you have a good solid 12 volts to all of the necessary ignition parts and check carefully to make sure everthing electrical is hooked up right.

Every time this has happened to me...it's always just something simple I overlooked.

thanks much! its got new points gapped to .018 the plug gap is 33 new coil and coil wire. when i set the spark plug on the valve cover it sparks, when you spray starter fluid in the carb nothing!! i checked the timing with TDC and still nothing.

Did you take the distributor out at any time.

yea and it would not go in any other way than where it was

its a slim chance but take the valve cover off and make sure the cam is turning ... my son had some problem had fuel spark but would not start= busted cam at the sprocket

Maybe 180 degrees out.

it has new timing chain and sprockets and it is in time

put it up on TDC on #1 and pop off the dist. cap, and see if it is on#1 or #4. That will tell you if your are 180 out.

crap!!! now i dont have any spark at all! new plugs even!!

Check the voltage to the coil then backtrack.

make sure your points are clean.set and rub block lubed then check for voltage.To check turn on ign. hold end of coil wire then break points open with screw driver then if you use at least 10 swear words then your points are working. I just couln't help my self.

ok, first I'm sorry you're having this problem. Second, My truck was down two weeks with the same problem, would turn over but no spark. As other's have already told you, check all the wires with a tester. Make sure you have power to the coil, etc. And here's the most important part, I replaced my Points, (didn't adjust them right), replace the condesor, (didn't tighten it enought) and here's the kicker, make sure all the wires are attached. (didn't realize my wire from the coil to the distributor had come off!!!!) I rechecked everything and when I found the wire hanging, reattached it and the engine fired right up. Came close to pulling the ignition switch to check that out. All I'm saying is when we get frustrated, we tend to forget a few little things, and that frustrates us even more.
Good luck

ok so i got nutty and ripped apart my wiring. the coil sparks as the key is turned off. i think there is a wire that is on the ignition in the wrong place

dose the coil all ways have power? my coil is not getting power

Here is some info on the coil

thanks very much for the help. i dont know what is going on!! the coil will not ark on anything. there started out having spark then it went away and it comes and goes as it pleases. i have wired the ignition my self now and still nothing. ive tryed differend distributors coils i now have 3 good coils.lol. i think that my ignithon swithc might be at fault. because the key is micro!! like a riding mower key. lol im out of ideas all togher.im thinking about yanking out 4wd and putting my brothers other 350 in. but i want a power glide before i go through that much trouble. and a beffy rear end.
