my truck wont start it turns over ive replaced ign coil cap and rotor and ign module. battery and starter and starter soloid it still turns over real slow and wont start it is getting spark and fuel is getting to the carb. any ideas guys. this thing is driving me crazy any help wont be nice thanks. it ran smooth as silk when i pulled it in. tried to start it couple hours later then all my problems started.

 

Please rephrase this, as I cannot understand what you are saying. Are you saying you replaced them, if so, was this before or after the problem? By the way, welcome to FTE.

 

i think that is what he is saying, he replaced all that stuff. i think?



now.. is is cold where you are? my 460 REFUSED to start in the -20 to -40 degree F temps we have been getting.

 

i would try putting gas in the carb, or watching inside for fuel squirting when you prime it. then if it does start you got a carb problem. otherwise if it doesn't try looking into the spark again.

 

How clean are the terminals? Are the battery cables in good shape?

I had a similar situation a week ago. I replaced the pvc plug and it fired right up.

 

Double check your wiring and firing order. If they are off by one in the rotation, it'll do what you're describing. There is also a duraspark troubleshooting guide floating around somewhere on the web, I used it and found things wrong I didn't even know about. One other thing, you can also have the ignition module checked at like an Autozone just like starters and stuff for free. Ok, maybe one other thing, there are also at least two different modules. They look about the same, except on the 4 wire connector side, the wires are in different order. Don't ask me how I know. Just thought I'd throw those out there. Hope it helps.

 

hey i have had the same exact problem with my 75 f-350 slow crank and no start what i had i to do for the no start is rebuild/replace the carb. my floats were sunk so it was getting to much fuel and just flooded it self out. what i figured out was that the fuel washed all the oil off the cylinder walls and caused massive amount of friction internally, after i got it restarted. it wouldn't run for crud, it used an 1/2 tank of fuel going 10 miles and it has the behing the seat tank. but any way that is what i had to do to fix mine try it and let us know

 

What is a pvc plug?

 

I meant pcv. The pcv helps emissions and needs replaced about once a year.
It is on the valve cover. It sits in an elbow in a hose that connects into the air filter cover.
