hey guys, just tryin to figure out what the firing order is. as i took off the spark plugs, i wrote down....1-6-5-2-3-4 but it is missing and backfiring. since all i could find in my 85 shop manual about firing order was for the 4.3, i tried that....1-6-5-4-3-2. that didnt work at all.

1-2-3-4-5-6

that's it for the FIero's 2.8

this might sound kind of dumb, but which post is that order starting at? the one bewtween the two screws on the distributer cap?

Try this, it should be close enough to work.

PLEASE, PLEASE, PLEASE, tell you don't own a Fiero without owning some type of manual that has answers to question like this. I mean you could have picked up the book and found the answer yourself in the time that in take to connects to the internet ? !! ?? DUH

You need to check and see if the engine is timed correctly. Take out the number one plug and turn the engine with a wrench until air comes out under pressure. At that point turn the engine no more than 1/2 turn until the timing mark lines up with the timing tab about the 10° mark (the tab has numbers on it, wipe it off to see them if you need to). The timing mark is the wide groove, not the two skinny grooves. At this point you should be able to see the piston at the top of the number one cylinder. Now remove your distributor cap and see where the rotor is turned. It should look like this:

Note the orientation of the six pole "fingers" to each other, and the direction the rotor is pointing. Whatever plug wire the rotor is under right now is the number one plug, and the firing order from there is 1-2-3-4-5-6 clockwise. If the rotor is pointing somewhere else don't worry, just make sure the number one wire is over the rotor and the rest of the wires are on in the correct order.

odd that the FSM would list the firing order for a 4.3, considering that the Fiero never came with one...
