Car shut down while driving would not restart and had bad spark knock. It is an 84 firebird with 130,000 miles.

So far I have replaced timming chain ,gears, and Electronic Ignition Module. Still no start.

I set upper gear with "dot" at top of gear with # 1 cylinder at TDC. This is what 2 seperate repair manuels said to do.

I am being told by others that the repair manuels are wrong and the top gear should have "DOT " at bottom of gear.

I spent 12 hours to do the chain and gears please tell me the repair manuel did not lie to me.

Car will turn over, and before I changed the Electronic Ignition Module, it started to fire up but would get spark knock and die.
with the new Electronic Ignition Module it wont even try to spark.

Thanks

 

Either position of the "dots" is correct. Both are #1 TDC. The one the manual referred you to (with both dots at 12:00) is #1 firing. That other one ("dot to dot") is the other instance of #1 TDC, where the #1 exh is just closing and the #1 intake is just opening, and it's also #6 firing. IMHO it's easier to assemble the motor using the "dot to dot" position, then rotate it to the other to put the motor to #1 firing and drop in the dist or check timing or whatever; but either is correct, as long as you understand which is which. I'm guessing and hoping you didn't remove the dist for any of this, so it's still lined up with the can correctly.

Sounds to me like you've done a bunch of work on stuff that wasn't broken, but now you've accidentally broken something by working on it incorrectly. So, it's time to quit just randomly changing out parts, and get the motor back to where it at least runs, and go from there.

I'd suggest verifying your module installation carefully. If it still doesn't spark after that, put the old one back.

I'd strongly recommend a compression test somewhere along the line. Go to Auto Zone and "rent" a compression gauge; disconnect the 12V feed (big pink wire) to the ignition system; pull all 8 plugs; block the throttle wide open; and test all 8 with a good hot battery, letting the cyl under test get pressurized about 5 or 6 times before taking the reading. Post the numbers here if you can't figure out yourself what they're telling you. I'm going to guess that you'll find one or more cyls with very high compression.
