I recently changed the distributor cap on my 95 chevy blazer. Vortex engine (4.3 L V-6)

i mislabled the plug wires coming off the cap and had to drive approx 5 miles with it misfiring to get it home. I have since got the correct firing order and rewired the plug wires to the cap. It wont start.

im getting fire from the coil to the cap, from the cap to all six wires. Plugs still look good and smell strongly of gas after ive tried to turn it over and then pull the plugs.

not sure what I did but any suggestions on where to be looking would be super (im not a huge car guy so please keep that mind and use "idiots" terms with me)

What color is the spark? It should be Bright Bluish/White.

You may also need to replace the plugs they may have gotten fuel fouled. Or try removing them and let cylinders and plugs dry out.

Yeah ive checked fire from cap to plug, and its good.

Ive pulled three of the 6 plugs and they are good

ive got the same print out sitting right next to me

plugs only smell of gas after ive tried to turn it over a few time, indicating im getting fuel to the plug, they arent wet and ive been on it for like 3 days so im sure any flooding would have evaporated by now

Yes, however, continuous flooding without a start can Fuel Foul Plugs.

Also have you check the fuel pressure and regulator?

One other thing that may or may not have an effect, you said you change the Cap did you also change the Rotor Button.

Ok, the rotor button is under the cap it spins around to fire each plug in time. It looks like this...

That is what I thought u were talking about, no I didnt change that, should I have? Or were you asking to make sure I didnt adjust it (which would throw off the firing order right? Again just trying to learn)

im gonna swap plugs out, and see if that helps

Yes, when ever you change the cap you should change the rotor button.

And no it won't through the firing off it will only go in one way and there is no adjustments for it either.

And we are here to assist in your learning, no matter how long it takes.

Got it working

it appears that whoever put the distributor in put it in backwards? The fiing order is the same as the diagram but the number 1 plug is in the number 4 posistion (and yes I double checked the diagram to make sure I wasnt looking at it backwards)

thanks for talking me thru this and helping me learn more about automotives

So, you were looking at it backwards/upside down and sideways and just don't want to admit it. LOL

Anyway I won't tell.

Glad you got it going.
