Why does my weedeater have no spark but a brand new plug?

Question

when you try to start it there is no spark but there is a brand new plug in it

Answer 1

Maybe the coil has gone bad...

Answer 2

Sorry I cant give you a definitive answer there's too many things that it could be like a bad ignition switch, a bad coil, a bad wire, a bad spark plug boot. You have to narrow all those things down to find and correct the problem. I would recommend bringing it to a repair shop.

Answer 3

Brandon - I have a question for you when you say 'there is no spark'. First off, are you making sure you are keeping the threads of the spark plug in contact with the engine (grounded) when you perform this test? If not, you'll never get a spark.

If you are keeping it properly grounded, and it is a new plug, it could be that during the removal and replacement of the spark plug wire, the wire may have gotten pulled to hard and broken. The next item, as others has mentioned, is the coil may be bad.

Just a thought! Good luck!

Answer 4

The coil is bad. if you have any mechanical ability and a good amount of time on your hands it is a simple fix. My experiences have been, that you have to pretty much remove most everything off of the engine to replace it. Good luck

Answer 5

Bad coil or plug wire.

Answer 6

You probably hit somthing very solid the last time you used it.This could have caused the 'KEY' to to be sheared. If you are somewhat mechanicaly inclined it is a easy repair.But if you decide to take it to a repair shop,make sure you ask to see all the parts that they say they replaced!!!!

Answer 7

If you used a spark tester, and are able to determine there is no spark, then it's likely a bad ignition coil or plug wire.

Replace both.

If you didn't use a spark tester, then I would recommend doing so before blaming the ignition system. There could be dozens of reasons your weedeater isn't turning over.
