I just got a 79 k5 blazer with a 350 2 days ago, its got the original 350 in it, the original 650 carb, all that. Anywho, I know of this service road thats rutted up and had some good mud spots on it. I took my blazer through it to test out the 4x4 a little, and it made it fantastic, didn't even put it in 4x4 the first pass through. Anyways, I drove down the road, lest I catch attention, and about 1/3 of a mile away, it bogged down and died. I thought it was just water in the carb, so I got a push home, tried every now and then for about a day. After a day, I got worried. I tried carb starter, didn't help. I pulled the distributor off and wiped the prongs and the bug off, tried again and it didn't start. My dad said I could pull a plug out with the wire still attached, and if it didn't spark at the end of the plug, then I wasn't getting electricity. Indeed there was no spark, but there was also a skip as it was trying to turn over. The distributor doesn't have a coil wire, just some wires that stick up the driver's side.

I dunno if the spark plug bit indicates anything, but thats all I've tried thus far. Any help is appreciated.

 

Does it have the distributor with the coil on the cap? Sounds like the coil has gone or it isn't getting 12 volts to it.

 

Yeah its the electric ignition. I just took it off and checked the coil. Its all dry. Thats not to say something inside its not fried.

Today I tried to put gas in the carburetor, that didn't work. Its got gas and its getting gas to it. I was wondering how or why it only ran that little of a distance. I was thinking I may have hit something and disturbed that gas flow. I'm not too farmiliar with this coil business on top, my 87 silverado just had a coil wire. Does that big circle thing in the coil hold a charge? I also thought it mighta only had enough charge to push me that far down the road and then went out.

So at this point, I know its still gettin' gas to the carb, its still crankin over, its just not firing at the plugs. All my plugs look fine, the plug wires look pretty new, so I'm guessing I either messed up the coil or one of the wires goin' into it.

 

replace coil, they are cheap. then let us know if that fixed it or not. if you have gas, then there is probably no spark, which could be coil, ignition module. also, with key on, check to make sure there is power at the BAT wire on distributor cap

 

Okay so... I've taken the distributor off, removed the coil, compared it to one at an autozone. It looked okay, the coil and everything was okay. While I was there, I also compared my rotor bug to a new one. The brass arm in the middle on mine was a little farther down than a new one. So, even though I thought it couldn't and wouldn't help, I bent that arm back up, slapped everything back on, and after about 30 seconds of cranking it started firing and spewing some white crap out of the carb. Then it started coughing and sputtering and crappin' out the tail pipe, and after about 2 minutes it was able to idle on its own. Now it runs almost as good as it did before, cept I messed a plug wire up seriously and pulled its' innards out and had to jerry rig it up to make it home. I'll also have to put some Heet in the gas, but in any case, it now starts and runs.

I dunno if taking the coil out and moving it around moved some water (didn't see any in it), or if it was what I did to the bug (it wouldn't make sense that something like that would happen from running through water), or if it just needed that much starting and pumping to work the crap out of its' system. But anyways, its now running. I'll be sure to let you guys know how it goes. I'm gonna throw some platinum plugs, wires, that stuff in it, and get some new valve covers with a pcv eliminator, and to get rid of that odd inch wide pipe comin' out of the rear passenger's side.

Thanks for all your help and insight guys!
