Crank, rumble rumble, stall.. Bad spark?
So I know I was involved in a forum post about this before, but I cant find the post again to enlighten ideas. The guy even put a video up. Anyway, here is my problem and I am almost 90% sure it just needs spark plugs.
First off, my car as usual takes forever to crank. When it starts, the thing sounds like it has a stage 3 racing cam on a big block 454... too bad the power doesnt come with the sound. It sounds like its running off 3 cylinders. I give it gas, it goes NOWHERE! And after about a minute it stalls after backfiring. I was thinking its not going to go anywhere firing only about 3 cylinders which is probably also making it sound like it has an AM cam, its also not going anywhere because the engine is probably flooding from no spark, and it back fires when a spark finally does happen, than finally stalls because of a major system malfunction, ie. everything listed, and clearly is telling me to go **** myself. So I just wanted to get some input on other ideas just in case Im missing something. Along with the spark plugs, Im going to change the wires and coil packs and starter finally and with the started comes all new cables, terminals, and terminal points. I JUST changed the fuel filter. The fuel pump will be the pay check after I replace all of the above. Just let me know if Im missing anything.
Mods include one simple thing - CAI with the breather filter.
Thank you =]

Is this the one you were referring too?

I really think you have a bad coil, IME a car usually won't start at all with a bad fuel pump. Have you tried removing the plugs off one coil and see if it runs the same? If there's no difference on one of the coils if the plugs are off that's the bad coil.

Im actually afraid to check the plugs. HAHA. The last time this happened in the cavy and it was the plugs, I found 2 of the plugs shattered.

Right now the car doesn't even want to start at all now because the starter is just about gone at the same time so I cant check it that way.
I haven't pulled anything off yet because I have been surprisingly busy. Lastly, I was going to replace the coil packs, but I ended up needing a new front bumper thanks to the hurricane.

Ill be pulling everything off either this evening or tomorrow morning and Ill let you know what happens. Luckily Ill be getting some free plugs. That bosche plugs give away on here where they request you to do a whole detailed review just contacted me and said they were sending them out. So hopefully that is the problem and I can have a decent review for them as well as a decently running Camaro.

Im nowhere even near one of those anymore. I might be able to catch a ride to one though. Im not good with abbreviations though. Thats the Idle Control Module you are referring to right?

Well I pulled out a spark plug and wire just now. Decided to save the rest for when the Bosch plugs get here for the review. I sent my itouch off to apple so I was left with my webcam to take pictures and needless to say, they are pretty horrible pictures.
Heres the spark plug.

(apparently html doesnt work here so heres the link to the pic)
Like I said, its a horrible picture. but basically the spark plug, is burnt and rusted out like crazy.
Here is the spark plug wire.

Again, you cant see it well, but the walls are completely rusted and the wire is so old its dry rotted.
Lastly, I dont have a picture of it, but the coil packs aren't in much better looking condition. I haven't pulled off the ICM yet so Im not sure about that. But after seeing what I have, Im pretty sure it was the spark plugs. Cant wait to get my new ones.
Also, I dont know if you can tell, but does the gap look wrong to you? I cant read gaps well to tell if they are good or not, but if I had to guess from a new one, than look at this one, this one looks pretty corroded away.
