lb9 no spark problem

as title says my engine wont start because of no spark what are some reasons for this. I put a new ignition module but that isnt it. What are some other reason for no spark. It feels like its not turning over as fast as it did when it was running

Re: lb9 no spark problem

In what ways could i test the pick up coil. I've never seen it but its somewhere on the bottom of the distributor right. One thing i might add is that sometimes i am able to get it to turn on if i let it crank for a long time (about a minute) it starts with a sputter hear and there and then it will run for about 30 seconds. And a little more background, it died when i came to a stop light. it was the first time it had ever seen snow since i had it ( first time i had seen it in my life, im from austin) the battery turned out to be bad too but that is replaced now.

Re: lb9 no spark problem

So you have checked to see your not getting spark for sure? mine was doing the same sort of thing, it was because i was getting flooded pretty bad, bad enough to where gas actually came out when i took the plugs out and they were soaked in it.
