i just pulled the #1 wire and put a good plug in and no spark. so i dont think the distributor is getting power. any ideas?
2007-01-14 13:42:11 · update #3
when i pulled the distributor i marked where the rotor was pointing on the cap and marked where the distributor was and it is in the right place. but i dont think it is getting any spark. could there be a bad power wire or something?

try new plugs and cords, disturber cap, or the battery needs to be charged.

Sounds like you have not arranged the timing for the valves correctly.
Check the manual and make sure the cam wheels are in the correct position. On some engines you could end up bending the valve heads if you get it wrong.
Have you connected the spark plug cables back corectly? If they are in the wrong order it wont run.
To check for a spark, remove a plug, still connected. Lay it on the top of the engine. Start the engine. You should see a spark.
Dont dont dont, go near the hole where the plug fits. Its petrol vapor coming out of there and its explosive.
Just realised, a 79 might not have electronic ignition. If it has the old style distributer then the spark timing might be wrong as well.

Pull the number one spark plug, reconnect the wire, lay it down on some part of the lower block and have someone turn the motor over, you should see spark.

pull a spark plug wire and put a good spark plug in to see if your getting spark i am willing to bet you have the timing off and or the firing order wrong

Maybe the Spark plug had some damage. Try a new one

first of all, you need to make sure the fuel and spark are present.
Next, you'll need to check if the cam timing are set correctly.
When all of this are done correctly, pay attention when you install the ignition distributor, make sure it is pointing at cylinder 1 firing position while the cam timing for cylinder 1 at combustion stroke.

Distributor could be 180 degrees out.

if it's getting gas and spark it's gotta go, check and make sure you have spark before you start tearing everything apart again.
