no spark...i think

[esty]

steve & i have been reading for a week and still can't figure out what may be the problem...his o2 truck decided 2st not to run properly,hard to start, requires priming carb...missing under load & rough idle...

he changed the points and fiddled with the carb to no avail...now it's getting fuel but there doesn't seem to be any spark and we don't have a clue how to test things...

there is power from the ignition to the coil, determined by a test light on the + side of coil when key is on...from there we're in the dark on what needs to be done or what to test

could it be a bad coil...i'd test the coil if i knew how

Esty, with all due respect (and I have a lot for you), if you put down the scissors and thread I think you'll find a wealth of info on your problem by using the Site Search function.

Good luck,

please revisit the points - if they are installed

correctly with the two contact points aligned, clean ,

and gapped properly while at the top of any cam

lobe to 0.015" feeler blade

also the wires to the coil and distributor

for breaks, sharp bends, loose connections,

dirt, oil, grease causing a short.....?

Maybe someone hacked her account LOL

If you have a spare sparkplug just remove

the boot from the sparkplug end and install

the spare plug and crank your motor while

holding the plug close to a grounding point

(Valve cover bolt). Also check for intake

leaks with a propane torch or carb cleaner.

I had a similar issue when my timing was

fiddled with by someone rotating the distributor

telling me it would give me more "power".

sorry guys...i meant to say that i'd spent a lot of time reading older threads but nothing help'd

i ordered new points & condenser and i'll swap a coil from one of the other o2's to eliminate the coil as the culprit

[BillWilliams]

Did he plug in the points and the condenser?

[esty]

Did he plug in the points and the condenser?

yes sir...both of us have double check'd all the wires & connections

[Scott Sislane]

did you swap all the plug wires & coil wire out w/ known good ones?

plugs & wires are new less that 100 miles

steve found new points last night and picked up a cheap coil, all he could find locally...he had to order a condenser that is supposed to be here today..

we'll see...

Don't forget to install the rotor :-)

Esty, Have you checked for connectivity from coil to condenser with an ohm meter? There could be breaks in between that may not be readily apparent.

ok...steve added a blue coil from another car, removed the ballast resistor & changed the points...the car starts...he said there's an issue with the new points though...the contacts don't want to line up...he's has a new pertronix and is going to try that
