Looks good to me. Paint the large timing mark with some white paint if it isn't already, and you should be good to go.

Put it on, now on to timing. What should the engine rpm as I set the timing?

Buddycraigg made some good videos on setting the timing on the Fiero. Make sure to jumper terminals A and B of the ALDL connector, or the timing will jump around all over the place since the computer will be adjusting it.





On my four cylinder I take the average of cylinder 1 and 4

At idle. As RWDPLZ stated, you must jumper the A-B terminals on the ALDL harness under the trim plate where the cigarette lighter is in the center console. Common practice for timing on a V6 is to clip the inductive lead for the timing light to the plug wire for cylinder 1, set the timing, then check the timing on the plug wire for cylinder 4. If there is a difference, you need to split the difference between the two cylinders so they register the same timing. I find it much easier to clip the inductive lead to the coil wire and you can set the timing for all cylinders at once.

But they all don't fire on the timing mark. How the hell do you know you're setting it to the correct flash?

this may be a waste of a post, but sometimes I can see where people ask the questions, but never give a result. Well here is my result...I followed the instructions for timing after installing a new harmonic balancer. After a small mishap with the serpentine belt not being in the correct grooves on the alternator (Didn't know it needed be pushed all the way to the alternator to be properly aligned) I was able to jumper the computer, and set the timing. The car starts immediately and is very responsive when the throttle is pushed. One other note, the idle stayed high for a couple of minutes, then I could hear the computer taking over the idle and brought it right into spec. I believe I read somewhere that when you take the battery out, the computer has to "learn" the idle again. Now I just need to move onto paint and figure out why the tachometer only works sometimes and I think I am ready to post some photos of the "all stock" restoration.

Cheers to all who have helped me in this thread!

You read and remember correctly. Ideally, it would be good to take the car for a little drive so the ECM can fully adjust. Anytime you start the car from a cold startup, it will idle high for a while, then you can tell when the ECM takes over and it idles down. Hope you get to enjoy the spirit of the road soon.

It'll just flash more often but that won't matter because you'll still see the white-painted mark at the appropriate times (IE, at cyl. 1 and 4). The mark will be out of sight 120 degrees away from the timing tab on the other flashes and thus you won't notice it. Unless of course your timing is advanced or retarded by 120 degrees but then again it probably won't run that way at all.
