when we went snow running on friday i had a little electrical fire. i burnt 3 plug wires on one side and a few vacuum lines. it still ran so i was able to drive it down the mountain. it did run real rough and at lower rpm it would die. i got it home and replaced the plug wires. it wouldnt start. i pulled the plugs and cleaned them. a few were pretty fuel fowled. i put them back in and still no fire. im looking for either a confirmation that the plugs are too fowled after cleaning and need to be replaced or something else that im not thinking about. like i said it did run and start after the fire. any input from anyone will be greatly appreciated. thanks.

i checked the wiring and cant find any that are burnt. the troubling thing is that it ran after the fire. i replaced the plug wires and now it wont start. we were on the 41 road and i drove it out and over to 4 corners and down into orchards withe the damaged wiring. now no spark. it sounds like it wants to but it just wont light.
Does it have points, may want to see if you fried them? Long shot but easy check.
Also could you explain what its doing like, just clicking when you turn the key, or is it turning over, or does it pop while turning it over like it wants to fire. Try pouring some gas down the carb if it has one. If no ignition then backtrack from plugs to coil to distributor.....Check fuses and connections as well.

it turns over but no fire. it does backfire after a while of cranking on it. its getting plenty of fuel. its electronic ignition. i did double check that the firing order was correct. it sounds like it wants to start then nothing.

ok here is the situation. i checked the firing order. ok. i checked TDC. ok. i replaced the plugs and the wires. it wants to catch but then nothing. its getting plenty of fuel. it seems like its not getting enough spark. it stumbles like it wants to start for a second then nothing. could it be the cap and rotor. they were new in march of this year. i did drive it from the 41 road to orchards on 5 cylinders and vacuum leaks. now with new plugs and wires and the vacuum lines fixed it wont start. my cell is 360-326-5813. please call if im overlooking something. it seems like after the initial stumble the ignition shuts off. thanks guys.
is your burb fuel injected? If so... then disconnect the battery.. charge it.. and try again.. will do two things. fuel injected needs GOOD power.. And... that time disconnected will reset the computer which may have adjusted for the bad running condition and will need the reset to get it running.. ( would readjust itself IF the truck would start and run for 10 minutes )
no need to respond.. just a couple more ideas for you. Dave.

ive been talking to mudmadness and we think that its the cap. i will be changing the cap,rotor and the coil. hopefully that will do it. i appreciate all the feedback from everyone. its been helpfull. i really need to get the truck going so i dont miss any more runs.
I have had trouble with caps on my chevy truck as well. I am running a MSD 6AL box with the accel hi fire coil. When I was driving it daily I would go through a cap and rotor about every 8 months or so. I would melt the striker right off the rotor and just shut off and wouldnt even fire after that.
I would try the cap and rotor and make sure there is no wires you missed if they got burned and fell behind the motor. Good luck.

Wyldman: The Cowbell... If you are a club member and you're on one of our wheelin' trips. If you get stuck on an obstacle and have to be pulled out by your winch or someone elses winch/strap. You earn the Cowbell.

poorboy: Wyldman, I got to see the passing of the bell at the meeting and learned quite a bit about the tradition.
