So i checked ignition module and it looks good, i sanded the prongs on the inside of the cap also and nothing still. I also connected the wire from the cap to the battery and still just cranks. Would a blown fuse stop it from turning on? I thought it was fuel but i opened the throats and put gas down and tried cranking but still nothing.

 

Check the rotor where the cap button touches the rotor, they have a tendency if not changed very often to wear a hole through and then the arc will strike the center shaft of the dizzy instead of making it's way out to the plugs.

Did you actually see a spark from the wire or just feal the shock? If it is getting fuel and spark and it was losing power you may have something mechanical happening here.

What kind of compression do you have? How many miles on this engine? Carbon build up on valves can lead to low compression and loss of power. Or just plain old wore out parts.

I would still double check with a spark tester on the wires first.

hope some of this helps.

also a coil can fail and still spark but fail to send enough energy to spark under compression. HEI coils are cheap might check that as well.

 

So i checked the plugs, wires, cap and rotor, ignition module, spark, fuel and still nothing. Does anyone have any other possible solutions? Thank you

 

Lets break it down,

your engine needs to crank over, create spark, get fuel, have compression

somehow you are not getting one of those. if its cranking over and your getting fuel , you're most likely not getting spark. on these 350s they are very simple. it can be as easy as 1 wire not getting power to your ignition coil.

did you take 12 volts to the distributor?

i would throw a new fuel pump on there too.

 

I can't seem to find the problem.............im getting ready to sell it

 

Having spark and having a properly timed spark can often be the difference between a vehicle that doesn't start and one that does. Have you tried changing the timing by rotating the distributor?

 

I am no master mechanic or anything but how come no one said anything about the engine getting the proper amount of air into the Carb? Spark, Compression, Fuel, and of course air....

If the Carb isn't taking in the proper amount of air or maybe one of the Air/Fuel ratio needles isn't set properly it wont run....

He said it was starting to bog down while driving, maybe the carb is clogged and cant suck in any air....

Try to ***** the carb with carb cleaner and check the air/fuel ratio adjustments

If your getting Fuel, Spark and compression the only thing left is air....or maybe it's time for a new carb

 

Good point. I have experienced a lot more timing related problems with older vehicles I have fixed than carb problems which is why I directed more attention to that area. But really, it comes down to a process of elimination and every process has to start somewhere.

 

How can I find out if the truck is out of timing?
How can I find out if the truck has a bad head or motor?

 

With a timing light.
With a compression tester.
