Hello- First post here, but I’ve been reading and learning for the last 6mo or so. I’m hoping I can get some assistance and some help problem solving.

I am having some difficulty starting my 272 after beingdown for some upgrades. I know itsdifficult to diagnose through a keyboard and more-so without all the info, soI’ll try my best to explain and list everything.


1958 F-100 V8-272(basically all original and all stock)

3-spd column shift - all original (points) ignition - Should be thestock 2bbl carb, etc


I drove it around a bit after acquiring it and seeing itsuffered from the ‘drunken monkey’ syndrome, I put it up in the garage for somenecessary upgrades. (New tires, brakes, suspension,…)

While I was at it I changed the coil, points, condenser,plugs and wires, fluids, battery…all the standard tune-up stuff.


By the time came to start her back up, it has beensitting for approx 2-1/2 months. It would not start.

-It kept turning over strong and would pop/fire out ofthe carb occasionally, then end with an “eerrrrrrrrr” sound. Tried thisover and over again but would never catch to start.

-After double checking the wire sequence, etc I wonderedit I had mal-adjusted the points. So ina quick fit I threw in a pertronix we had laying around the shop (new andcorrect model#). It just did the samething…over and over.

-Thought then that it might be the timing, so I loosenedthe distributor and twisted it left, right in various increments …it either didthe same or worse. THEN, while still attempting it …I saw the battery arc fromthe terminal to the firewall and all went dead. Dead as a doornail.


This is where I stand now. Regarding the scary ending I’m guessing Ididn’t have a good ground somehow (perhaps from loosening the distributor??)

I am quite certain that would have fried the Pertronixmodule and probably why it is super dead right now. I have purchased a new Pertronix and new coiland will attempt this again this week.


Number one, I don’t want to fry another Pertronix….number two, theengine still wasn’t starting….and number three, what about my ground(why thearc)?

Can anyone give me advice to where to go from here?

Many thanks-

Don't install the Pertronix until you solve the issue. It sounds like the old ignition components worked and you changed them as a preventative measure. Put them back in and go from there.

One of the first things that comes to mind is that the firing sequence might be off.

15846372, with cylinder #1 being the front on the passenger side. Crank rotation viewed from the front is clockwise.

If you have a spark, the coil is probably ok.

If you are getting some backfiring and popping, you have some spark.

I agree you should put the old stuff back in, get it started, and then change one thing at a time. It's a good idea to always change only one component at a time and then check that it still fires and runs well.

It should at least get started... you have spark and you have compression right? all you need is that air/fuel mix and you have the 3 things to get it running.

my vote in all this --- that firing order on the distributor cap is counter clockwise - double check that first. Then bring number one cylinder to TDC and see where your rotor is at. Set your distributor to fire right on Number One cylinder, and then go from there.

The reason I say the CCW rotation is your "pop and flame" comment...

Dunno what to tell you about the arc

Yep, all along I was concentrating so much on firing ORDER and plug ORDER that the cap being the wrong rotation slipped by me everytime I "checked" it.15486372 going Counter-Clockwise was the ticket. ...just like you guys suggested.



Before breaking thru, frustration setting in....




This old Cap "MADE IN USA" that I had wrote the numbers on months ago woke me up to what y'all were saying.

Running well! Elation!

Just for info- Rotating the engine to find TDC, like Daniel/KIT suggested....I found this mark. To the right of it there are the tick marks/timing marks. Is this mark TDC ?

Again, I cant thank y'all enough for your help. I'm away for the weekend so hopefully I can get back in the garage next week. I'm going to keep the points and current ignition on for a little while. Next up, I'll be asking loads of "timing" questions, so run for the hills.
