SOURCE: v6 blazer/code 300/changed plugs,wires,coil,vaccum

Wet weather starting and missfire problems are almost always in the ightion system. The cap and rotor are the most common reasons and the coil is next. Code 300 is random multicyclinder missfire. The coil wire even if it's good can get intotroble. Something that's fun to do if you can is to watch the motor while your trying to start it in the dark. Sparks should'nt be ging anywhere so if you see some those parts are bad.

My Blazer cranks over and over...killed the battery : morning the second time I tried cranking it over it made a poof sound and started but with a lot of chugging. Can anybody help please?

Lynda, If it is the 4.3 V6, they are prone to getting moisture in distributor which causes the symptoms you are talking about including the poof. You can have scanned to see if trouble codes are stored, you may get multiple misfire.
If continues doing this have cap and rotor replaced and if wires and plugs are old do them to. Check the attached links,instruction and guides, Good luck

Can moisture get in the cap and cause the vehicle to not start?

This is a very peculiar malfunction with your car that cannot be fully diagnosed over a computer. Contact a mechanic.-----------------------------------------------------------------------------------

I have high voltage at the coil out put....ICM test ok have not checked crank sensor... will not start fuel supply ok

High voltage at the coil means nothing. Hook it to a plug and hook a timing light to that cylinder. If during cranking the timing doesn't flash, you still have ignition problems. Note, it must flash during cranking. Hold trig down.

96 chevy blazer won't start

When you say it doesn't start...Does it crank over? Does it need a jump??

Assuming that it cranks, but doesn't start...

If it's a moisture problem there could be a problem with the distributor cap. If there's a crack in it, or it it just isn't sealed well enough. It'll crank-n-crank-n... Until it's warm for a day or so. I just went through the procedure on how to replace it for the novice, same vehicle. Take a look at that. In the interim there's a spray "wire dryer" that might help, or he could spray some WD-40 on the cap.

Another way to check is to wait until it gets dark and get a helper. One person cranks the engine, the other looks at the cap and wires. If there's any sparks from the wires, or a crack in the cap, it's a lot easier to see.

My 1994 jeep sport 4l won't start it won't start for the first time when I washed it at the car was washed under neath and under hud, left it runnung, then shut it of and it would'nt start. next day it...

You should never wash your engine. It can really mess with the computer sensors. However since you now have a problem in the rain, I'd change the wires, cap and rotor. (likely old and sensitive to humidity) Also, look at your ignition coil in the dark...if you see any spark or electrical "haze" where the coil wire goes in, change the coil.
