Wow! Have to say impressive! Very well explained and leaves little to doubt! I changed my ignition module and it still didn't start. I swapped out a coil from one I've seen run. Still didn't run. But I noticed a lot of rust inside under the rotor. Pickup coil and everything is rusty, so I bought a used distributor shaft complete. Add my plugs and wires to the coil, and I'm back running!
Thanks very informative been wrenching for years and learned something new an so important .Very helpful and easy to understand an so calming!! Yepyep in my book.Have a great day Sir an Thanks Again for Sharing
Thank you, you help me a lot. now I know why my GMC Safari won't start. I put new coil new module, new cap and rotor but didn't wanted start so now I know its the distributor that is bad.
I just converted my TBI to a carburetor. Can I eliminate the ECU plug and just run the positive and negative from the coil to the distributor? I already have my purple and white fuel pump wire hooked to my tach wire for the pump to run properly. I bought an HEI but with the 4.3L V6 with the carb its super tight and cant get proper timing with it.
3 years after you posted this video I' m watching it, I' m looking for videos about my 94 c1500 4.3 l with a TBI Distribuitor. My truck died saturday night, no start no spark, hired a street mechanic because Sundays the shops are closed. He end up replacing Distribuitor cap, rotor, ignition coil and ignition control module and after all the new parts replaced still no start no spark. Today monday mornig the mechanic did not show up. I guess he gave up, I'm not a mechanic but looking your video I think the problem it's inside the distribuitor or all the distribuitor assembly needs to be replaced. Thanks for the video.
Does the distributor in the middle have a 2 and a 3 wire plug. I think that's what I have on my boat. When cold will start and run to 2500 rpm then rpms drop as I give it more throttle. Then if I shut of motor it wont start til next day.
Did you ever figure out what it was. Mine will run fine then it falls on its face and i can smell it running rich. Any help would be appreciated. Here's your one chance youtube dont let me down.....lol
Salutes TJ664 need help i have a 92 chevy silverado 2500 5.7 starts fine but after 1500 RPM +/- sudenly dies it doesnt send more spark to sparkplugs We start again and start normal but increase the RPM and dies what can be the problem thanks
That's a good test and maybe you can get it running but it's not the whole story. Just cause you got some spark doesn't mean all is well. There is a number of things that could be wrong with them that this test won't show. I only say this because I just installed a new distributor in my K1500 cause it was running poorly and I know if I performed this test on my old worn out one I would get some spark.
I may have forgot to mention in the video the coil has a heavy gauge pink wire that goes to positive on battery. in vehicle its a switched power source.
You don't need the computer hooked up for these to work, you even prove it in this video!! LOL The only thing the computer does is control the spark advance.
I always carry a spare mod. In the glove box. When they go there's no warning. Engine just quits running where ever you are. They are E Z to fix on the road side.

Super video! Thanks for posting! Seeing that spark was amazing! (And you took it like a champ!!)

Beautifully explained thank you
I say rock on brother rock on man that was a pretty damn good video about distributors
Thanks that's very helpful

What did you use to plug + wire in to the coil
Thanks Alan.
thanks brother appreciate it
What if the ignition module is bad?
How would you test the coil and the ign. module?
this video helped me figure out a no spark on a truck thanks
when does the dizzy spark? when the metal cover covers the gap or when it passes by?

Thanks for watching! I’m glad it helped.
What did it turn out to be the no start problem?
@@tonywalker2334 The ignition reluctor inside of the distribuitor was broken, that was the problem.
well done

No it does not.
My ignition wires have been cut off the wiring harness. Where are the wires located to hook them back to the harness
Awesome
Question is can I run the HEI in place of the TBI disturbtor After running around 10 min it cuts out and over fuels. Thanks for sharing your video!!
Yes you can run the hei in place of tbi. you will need to do some wiring to make it work properly but can be done.
Did you ever figure out what it was. Mine will run fine then it falls on its face and i can smell it running rich. Any help would be appreciated. Here's your one chance youtube dont let me down.....lol
Thank you, very easy to understand video the + wire to the coil is it white or pink I cant tell in your video, other than that very well done
the + wire is the heavy gauge pink wire going to coil. The smaller wires are for a tach hookup and other stuff.
Would it still spark if that jumper ground between coil and distributor is disconnected?
im not sure if it would.

Can I use a regular coil on this distributor ?
How the wires will work ?
On these distributors it is best to use the factory original coil.
That's a good test and maybe you can get it running but it's not the whole story. Just cause you got some spark doesn't mean all is well.

I agree 100% there are more accurate tests than this. But however this is a good test just to see if your at least getting spark.
sir how to wiring coil to battery please
I may have forgot to mention in the video the coil has a heavy gauge pink wire that goes to positive on battery. in vehicle its a switched power source.
hey my brother you didnt have to take the value cover off to get the timing right
You don't need the computer hooked up for these to work, you even prove it in this video!! LOL The only thing the computer does is control the spark advance.
"Are you shure that's how ya test'em"??..
I always use zig zag
