Hi guys,let me explain what's happened.

This morning a 6 o'clock my blazer started very well to go at my work.After my work day at 4 pm It wont start.crank,crank and crank absolutely nothing.We had a big snow storm during the day.When I opened the hood I realize that some snow introducing in the battery and computer area.Can it be something in relation with the moisture ?I think that yes because I remember a month ago it do the same thing in a rainy temp,start,start and start but finally for this timeit started...but not today.

about 9 pmtonight I return to my shop for a retry...It almost start but not.(it do some effort),compartively at 4 pm=no effort.

I would like fix it right in my parking shop before calling the towing...$$$
I planned to install a new cap and rotor first Sunday.

What do you think of that guys?
Any suggestions?

Thanks very much!

 

Quick and easy, try a cap, and rotor. If it does this in the wet weather, it sounds like that will fix 'er up. But if that does not fix it, you will need to check fuel pressure, and spark. Korey

 

From what it seems like is that it only happens when there is water (rain) or snow that gets under the hood right?

If so this could be a sign of a cracked cap. Try removing the cap and drying it off (inside the cap) if there is water under there. Then the cap might not be sealing right or it could be cracked. Visually check it and if it is cracked then replace it.
