Misfire Stall Or No Start? How To Check Your Distributor Cap For Common Problems.

Good learning video, amazing mechanic.

What happens of the rotor moves around while changing the cap ? Will it mess up the timing ?

Great video, yo. Props.

I have a 78 dodge Sportscoach 440 b300 mobile home at the moment inahbe issues on a cold start. ot will turn over, but it will shut off immediately. it may run for 20 seconds. I was thinking of a faulty fuel pump or needs carburetor adjustments. my reason for thinking something witu fuel is because I'm thinking I have to pump the gas like 50 times evern thogh thr pump was changed about a year or two ago amd it hasn't even ran much. once I get it to stay running, it does fine at restarting throughout the day. it does fine for 6 hours sitting, and I'm not sure what's the final amount of time till it gives me issues again

Hello! I need some help!! Im at a lost with my 81 jeep wagoneer limited v8, i replaced sending unit,vents,fuel hoses,starter,capstiol,coil,pickup coil,wires,rotor, distribution cap,just everything i can think of. Still it will not start it turns but no start. Im beating myself in ass wondering wth could be wrong. When i brought it home it started and it out for a spin and came back and parked it and since that day no more starting then when i started replacing everything i could think of!! You u have a clue what could be wrong????

Thank you my friend. I have searched and searched if the rotor is ok if it's got a little play in it, and mine has a screw so no chance in it coming off. Now when I say play I mean almost to the point you can't turn it, but I saw yours move about how much mine does when you touched it. God bless you and thank you for a very informative video❤️🙏

Love it

Very clear good advice

Thank you very nice video 😊

Good job

Mechanically inclined but not a mechanic, first time this was really explained how it works, appreciate you bro, good stuff.

My car not shifting over after a new distributor can anyone help me out

Thanks for the information

I have an 87 dodge d150 with the lean burn computer. My center nub on mine does appear to be worn down but I don't think it moves. I'm trying to replace the pickup coil right now. Never thought about the cap itself being the problem.

Great vid, Big like and Thanks, How about to waterproof the distributor, is there any chance to do it?

do all the center button spring/move?

Thanks, good videos. Can fixing the distributor cure a misfire? I have a 0300 code.

straightforward and educational for the everyday driver. thanks!!

yessir.. another topic for the distributer... moisture ! and I live in Houston, where its 100% most of the time. again thank you

"water displacement - forty" takes care of the moisture in the cap and it's non-conductive, then wipe with a bit of toweling. if I don't have tools on board, I make sure I've got my Leatherman (don't leave home without it). 😁✌

Thanks man. You sure saved me a lot of time.

👍👍👍

I have a similar issue with my 95 SL500. I doubt the caps/rotors have been changed since the 00’s. When I checked them, there was all sorts of carbon tracking, corrosion and gouging on the contacts as well as condensation. Ended up sanding each contact a little (I wasn’t too thorough) and it fixed the misfire for about 2 minutes. Currently waiting on all of my parts to get here; hopefully that’s the issue.

Awesome video. Thank you.

Do all cars have a distributor cap? I have a WK2 Jeep Grand Cherokee, but havent been able to locate it yet

I got a Ford sierra 1987 V6 GLX. That does not want to start. I replaced distributor cap, the rotor and the point, I also changed the condenser, plug wires, new coil and new spark plugs. My timing is on point but still it does not want to start.

I have maruti omni,i replaced the contact breaker 2months before,but it again leaves during traveling and then i took the car to mechanic,he adjusted the points and it runs well for two weeks but again the contact breaker points leaves,What the reason behind it?

Saved me I’m a noob

Ibe got the 94 ls 400 and currently trying to retime what I believe is the ignition timer.

TDC is marked on one housings where two caps were replaced along with in the same spit the rotors where changed. One of them is set perfect but it's the other one which didn't have a mark like the other one was for TDC to know how far 10 degrees was. Giy working on my car who use to be a good friend up until this does know his way around an engine. But if you know anything about a lexus ls 400 eng8ne you know this thing is a beast and has so many parts that it takes quite a lot to get this done. Anyways where he thought might have possibly been a mark for TDC he used and used that to adjust to the 10 degree but alas it was wrong. Why he put the whole car together before checking his work us something I can't answer but to express how utterly lost I am at understanding just how far this issue can go isn't nearly enough.

I'm assuming all but this one is fine.
From my knowledge there are just 2 distributor caps and 2 rotars which are the only two things I know timing has been adjusted on and if he's right about the one then only one of these two things are set wrong.

My biggest pain in the ass is understanding ehat the heck that cap went onto? The distributor? So the rotor powers the distributor then or what? For some reason i thought it was a cam. As this engine has 4 of these damn things so as you can see with that info maybe you'll have some empathy for my frustration and see where it's coming from.
I'm looking for someone to give me some clarifications to understand what the hell to look at or into to try and fix this problem.

It's likely really fucking simple beyond the taking shit apart part and involves a few twist here and there I just need to know where that is

Speaking on the wire diagram I have a stack of photos of firing order sequences lol those really help but putting a little mark on em isn't too bad of an idea

That was very helpful!! Thanks

Thanks dude

Very informational I clean mind like you describe and I me back on the rd. Planned changeing cap and roter thanks.

Great job

Got anything on 06 silverado lu3 v6. P.s. thought I was the last Shaner good to see there's more of us out there

I got a 92 f150 4.9 liter and ive replaced about everything except the o2 sensor (because i stripped it out)..... but anyways i checked my distributor cap the other day and seen like metallic dust/powder all around the center button and likewise on the rotor itself and some was around the inside of the distributor as well. Could this be whats causing the truck to miss/and buck-jump after i drive it a very short distance.?? Like I'm talking about down my street about 2 to 3 blocks and then its like i can barley make it back home because i got no power and i can put it in neutral and rev it a little but as soon as it's under load it doesn't want to go and is missing like crazy. No backfires though. I can rev it when i first start it all day, and it does almost perfectly (except a little miss every now n then).
So im stumped and need some help if anyone can suggest. Thanks
Liked the video sir! Good job.

Thanks for the video man got right to it and didn’t keep me waiting

Bad ass video thanks

Thanks for the informative video

Beautiful job brotha man. I just did a tune up and decided I wanted to wash my 1977 Chevy 350 motor and after I did I was getting a misfire. Now I know what to check ✔️. Awesome 👌

is aluminun or brass contacts better ?i need a new distributor cap and i have 2 options brass or aluminum

Yup, I had a no start. Pulled a plug wire, plugged in a new one grounding it to the exhaust manifold and cranked it, I had spark. Sprayed some starting fluid into the throttle body and cranked, no fire,,,,what? Got spark (so I thought) and spark juice. Ran perfect the day before. Checked all the fuses and relays, good. Checked fuel pressure and pump, good. Pulled cap off and center pin was broke off,,,,dang, never seen that before. How did I see spark when I plugged in a skate plug,,,,baffling!!!! New cap and smooth as silk again.

Very helpful thank you

Helped tremendously on problem with sons chevy truck ,mechanic did a " tune up 1 week ago supposedly truck still cutting out 528$ later

really good sir thank u I own a 2978 f150 with only 92,450 original miles barn kept not drove for 15 yrs

You have answered my questions. Very helpful. Thanks

I have a 1979 Lincoln Mark V that is having firing problems. Thanks for explaining how it works and how to replace an old distributor. I'll be back on the road again very soon!

Thank U..

very good- i use a dremmel type tool to clean the corrosion off the terminals... and use electro-spray cleaner, dry thoroughly

Very helpful 🤘🏼
