Desparate for help!!!
please, I need some help with spark issues
<HR style="COLOR: #666666" SIZE=1>I'm new to this site, I hope I am posting my question in the correct arena. I own a 87' Big Bronco. The other day it started blowing black smoke, so i changed plugs, wires, rotor and dist. cap, coil, and idle sensor, because the idle was fluxuating up and down. Now the truck will not start at all. It turns over fine. However, when I checked the spark from the coil, there is Very little spark to be seen, just a small blue flicker. Can anyone advise me? I am lost. Thanks, Scott in TX

The engine is a 302. When I replaced the wire, I would pull one cable out at a time and install a new cable. The coil: Duralast c839 from autozone. Both the old and new coil show very little spark.......Scott

you say its blowing black smoke eh? well that means ur burning real rich. (too much fuel) i had a problem like this a while back. i was driving down the road and i accelerated and it sounded like something gave way or like i had hit a wall. anyways i was blowing dark blue smoke all over the place. it would turn over just fine. but it would start. but then eventually it wouldnt start anymore. what had happened (and i should have realized this before hand bc my gas mileage had dropped a little bit) but there is some pressure valve or somethin on the gas line near the intake manifold and it had gone bad, therefore allowing too much fuel to go in to the engine and burning dark. this valve thing is 2" round and bout 1" thick. this thing was broken on my truck and its cheap to fix. i hope this helps. it probly wont start b/c its flooded. let me know how it goes
