No Spark?

just did a bit of beach wheelin' and i was crawling through a bigish hole(water just over the tires) the engine died. crawled throuh it cus i was having problems with the motor not wanting to stay alive after driving quickly through small holes, and water filled ruts. anyway, it didnt suck water into the intake, and the distributor was dry. i pulled the cap, and spayed a bit of wd40 in it, checked all of the terminals, checked battery posts, any wiring, fuses, and whatever else came to mind. then i pulled a spark plug, and no spark. any ideas??? all new ignition stuff, except, im still using the original coil. bad coil maybe? if its the coil, why would it decide to go out while i was in the water? and what about the motor not wanting to stay alive after the other water holes, and ruts? really need some help, but i guess thats nothing new...

ignition module would be my guess...

got sidetracked...

those symptoms sound like a module freaking out to me.. maybe a hairline crack in it... pretty sure you can get em tested at the parts stores..

did it get better or worse when hot before it crapped out?

what do you mean by "hot"? like drying out/warming up? before it crapped out, if in fact it is the ignition module, i would go through some water, and the motor would barely stay alive for a few seconds, and then die. start it back up, it would do the same thing. couple more tries and itd be fine, like nothing ever happened. so instead of getting any speed before entering the water, i would just crawl tough it, and no problems. that is untill the big hole. so i think something with the ignition is getting wet. ive got the msd 6a mounted near the top of my inner fenderwell, but that was going to be temporary untill i got around to making some longer wires, and putting it in the cab. i thought they were supposed to be sealed though? but maybe its got a crack in it somewhere like you said

Hey Rich.

If you haven't already you may want to go to msdignitions.com and have a look. Click on TECH SUPPORT, click on TROUBLE SHOOTING, click on CHECKING FOR SPARK. There is a small amount of information that may help or give you some ideas.

You may want to just look everything over carefully in the morning. Make sure your mounts are tight and dry. No loose wires, good ground.

The only real limitation I can find on mounting is not mounting it upside down. Sorry I couldn't be of more help.

Good luck, Jim.

If I lived close by I'd be happy to help you get it out. Maybe someone on this forum is near you and can help out. You never know.

Good luck!
