truck wont start still... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

oldblue1968chevy · 06-04-2009, 04:41 PM

im getting fire, getting gas and air, under dizzy cap is turning rotor button is good looking.....WHY WONT MY TRUCK START!!!!

first i had a bad starter, 50 bucks later, a few choice words, and 45minutes of my time, i gotta new starter on....

now at least it turns over...but still wont run...any ideas

matchstick · 06-04-2009, 04:46 PM

IS it flooded? If you're getting gas and spark you should be running.

Shyguy · 06-04-2009, 04:49 PM

What kind of distributor do you have?

You said you are getting fire, is it to the plugs?

Has the truck ran and now won't start? If so what has changed since it ran.

Sorry for all the questions, but a little more info is necessary to better help you.

I have heard on here before in order for an engine to run it needs fire, air and gasoline. Also it has to be firing at the right time.

oldblue1968chevy · 06-04-2009, 04:56 PM

electric i guess hei dizy

parked it the other night to jump a wheeler off, left it where i pakred it went out the next am to get a haircut and it wouldnt turn over, well today i went to buy a starter, put starter on, now it turns over but still doesnt start,

gets fire at the plugs
dumped gas in it, and it gets gas
nothings changed since it ran last lol, cept a new starter, and me movin the dizzy retard/advance......

sandking · 06-04-2009, 05:13 PM

Timing, timing chain, fuel to the carb, screen in the carb inlet, choke stuck, etc.

Have you checked the fuel level in the carb bowl(s)?

Have you checked spark at all plugs?

oldblue1968chevy · 06-04-2009, 05:39 PM

havent checked spark at all plugs

i can see a lil gas in bottom of carb

screen in carb......ive dumped gas in it, but it may be getting stuck at the screen

its an electric choke.......its not even hooked up lol

cdowns · 06-04-2009, 05:43 PM

checked spark at how many plugs// HEI or points distributor?

oldblue1968chevy · 06-04-2009, 06:21 PM

just #1 plug

hei

Hottrucks · 06-04-2009, 08:21 PM

take the air cleaner off and flip the thottle a few time and see if it's squiting gas...if you have gas and spark you have a runner.....is the carb pump doesn't squirt start checking you fuel system

69halfton · 06-04-2009, 10:45 PM

does it do anything? kick? sputter? show SOME signs of life or nothing at all?

id check all the plugs to looks for spark. even just check that all the plug wires are on. there has been stupider things happen that will keep a truck from starting. ask me how i know.

tim21391 · 06-05-2009, 12:04 AM

on my dads 67 mustang.. a vacuum line popped off and so it wouldnt start... maybe it can be something that small.. maybe that pcv valve came out or something

dznucks · 06-05-2009, 05:54 AM

you say you jumped a 4-wheeler off......you might want to check your dizzy. i have seen a dizzy fry before just by jumping off another vehicle. i would take the module out and test it.

oldblue1968chevy · 06-05-2009, 11:50 AM

checked the dizzy..

why would it fry from jumping something off?!!!

ive gotta nother one i can exchange......

will go play more when i feel like stomping in the mud (its nasty outside)

oldblue1968chevy · 06-05-2009, 01:08 PM

well, turned out it was my type of working on the truck lol

went out, sat down in seat to think, turned key...and bam it started lol

now we've fooled with the carb. soo much its way out....wont even hardly run...

anybody have any kind of idea the settings are supposed to be, its got 2 screws on the front, which are currently all the way screwed in...im bout to google it to see what comes up, id like to know even wat the diff. are which one leans/richs it out

**WorkinLonghorn** · 06-05-2009, 01:28 PM

I think both idle air screws should be turned 2 turns out to start with,then fine tune from there to smoothest idle or highest vacuum if you have a gauge.

It will not run with them both turned in all the way.

UltraBlue71 · 06-05-2009, 02:39 PM

I have had spark fuel timing everything working and not have the engine run, you need compression too, if the rings are shot she wont run, I learned that on a S-10 a while back hooked up the comp gauge and had 0-5 psi in each cylinder, the PO had run her out of oill and the rings are gone, not typical, mind you but it happened to me!

Shyguy · 06-05-2009, 06:17 PM

Yep, you are right no compression-no run.

Good point.

That is what I like about this site, everything is brought up at one point or other.

Danny

oldblue1968chevy · 06-05-2009, 06:21 PM

runs good now...but i didnt add oil and i have 0 oil pressure...when i rev it the oil pressure gauge goes up like a tach. lol its aftermarket guage...and dipstick reads a lil too much oil, whats that saying?

**Boog** · 06-05-2009, 08:02 PM

Uh oh. Too much oil and you didn't add any? Is the oil milky looking? How's the radiator coolant level? Does the engine rattle or knock?

If they were scewed all the way in you probably fouled your plugs.

oldblue1968chevy · 06-06-2009, 09:59 AM

no i just screwed em in never ran it like that

i did get it running

i had gas in my oil,ima change fuel pumps today (try to atleast) and may change carbs for awhile (goin back to quadrajet from edelbrcok)

anybody know how im getin gas n the oil?

i flushed it out, drove it fro bout 1.5 mi with oilygas then flushed it, will flush again soon tho

How much fuel did you pour in the carb trying to get it running? And how many miles does the engine have on it? Just a guess, but you may have poured so much fuel in that it seeped by the rings into the crankcase. Seen it happen before.

As far as reading 0 psi at idle, there was probably enough fuel in the oil to thin the oil out. Get fresh oil and a new filter on there ASAP.

RustyParts · 06-07-2009, 08:12 AM

Gas can also get in the oil pan from a ruptured diaphram in the fuel pump.

**truckdude239** · 06-07-2009, 08:34 AM

if u ran it with gass in the oil for 1.5 mile you looking at min a bottom end rebuild gas will wipe you bearings in a heart beat causeing a no oil pressure at idle

69halfton · 06-07-2009, 09:03 AM

oldblue, when you said jumping off, I think dznucks thought you ment jump started with cables. where I think you ment jumped off as in drove off the back of the truck. which you are right, would not effect anything

..just to clear things up..
