Just take thick gauge wire from the starter and connect it to the distribution block and you should be ok.

It just so happens I found the broken wire today. The wire is hot (12V \10 gauge) I can see that the terminal is broke off. But I am not sure where it broke off from; maybe the starter. I was thinking I would take this wire and extend it to the fuse block but add a fuse\circuit breaker just to be safe. I am just not use what amp fuse to use 30 /40/ 50 /60 any recommendations?


It also appears that I fixed the misfire. I think the optispark was the problem. I only ran the car for a few minutes since I am still working on the cooling system.

There's no need to add a fuse to that wire. I used an 8-gauge wire from starter to junction box.

Well, as I stated before, the opti is almost always the source of misfire.

Close the spark plug gap.

I should be working on the cooling system later this week and can run the car longer; hell maybe take it for a spin. Hopefully the misfire is gone but if its not, I will re gap as suggested. If I recall correctly they are at .55 the factor gap for the plugs I got.

Hello all,

The BMW electric water pump is installed.... I ran the Fiero for 5 minutes and no misfire. YEPPP.....

I wanted to run the fiero for longer but I realized

1. I forgot to plug in the lower vacuum tube for the Optispark and I can't get to it now with everything installed. I'll need to remove the Crank pully.
2. The belt is not aligned correctly. There is a 1/4 inch difference in alignment causing the belt to ride on the inner part of Crank pully.

Question: Can I have a machine shop take 1/4 off the crankshaft the rear of the crank pully to get the belt to align? See pic 2 for reference.




This second pic is for illustration only; not my crank pully.


LaFiera,
I had a harder time getting the water pump installed because I didn't have that much room as you. I still have the front tube and my battery is located up front.
But thank you very much for the help and the pic's.

Just shim the alternator/AC bracket with washers/shims to align the belt

My pleasure my friend! Did you get the controller also?

That's a great idea; but there is latterly no room for me to remove the bolts without dropping the cradle. Thus, I was hoping to remove material from the crank pully. Is this an option?

The crank pulley bolts to the crank hub.

So you would have to shorten the crank hub, which is possible, but I don't know if doing so would create an interference between the crank pulley and optispark distributor.

I don't know how your setup is, but on mine I have no problem removing the alternator without dropping the cradle.
