hello,

i have a ?.
i have a 1988 gmc s15 jimmy with the 4.3l engine.
my question is is that when i have the car started and look at the Ignition coil.i can see a spark.is that normal

If the spark is jumping out of coil or wire you have a problem.

Start with checking the coil and plug wirres.
Make sure spark plugs are good cap and rotor are good to.

hello,

yes its coming out of bottom of the wire that is on the ignition coil and hitting the metal wall of the ignition coil..
is there supposed to be any open spark anywhere.
because i have one there and it goes tick tick tick tick tick tick real fast and every time a spark comes out.
if i can i will try and get a little video of it.

so what could that be and what should i replace.

when i lifted one of the wires up on the distr. cap white powder poured out of the one.and some wires inside have the metal inside them rusted.and the distr. cap has white residue on some of the little poles sticking up. would that cause it

see this pic.

where the arrows come from at the bottom of where the wire would be.thats where the spark comes from.and hits that metal post that the arrows point to but on the bottom wheer the spark plug ends.across from there on that metal wall on the ignition coil.

is that normal?and if not what could be causing it

Check and replace the plug and coil wires and check dist cap and rotor and plugs.

If spark can not go threw wires and cap and plugs it will find a way out some place.

so there is not supposed to be a spark at the bottem of the wires that sites on the ignition coil. like i showed in picture.

It should not have spark there.
Replace the plug and coil wires and check spark plugs and dist cap and rotor.

If spark can not go from coil threw wires and cap and rotor to plugs it will burn threw and jump out the weakest point.
Which it is doing now.

If after good plug wires and cap and rotor and plugs it still jumps out there replace the coil but only after good wires cap and pulgs.
