Im looking for a wire diagram for a 1968 camaro it had a coil but now im useing a vacume distributor and dont know how much i can get rid of preferably a free diagram

Is distributor turning?
Is there power to dist?
Is there power to coil?
Is there a resistor on the coil, is busted?

1-8-4-3-6-5-7-2

TDC on #1 compression stroke,not exhaust

Number 1 on the dist cap-- is at about 7 o clock,
as you face the motor from the front

2-4-6-8
1-3-5-7

1&2 are at the front-- as you face it

The base of the carb location sounds like the vacuum spark advance for the distributor. Look for a (possibly broken) approx 4mm pipe on the distributor body.

Are you getting power to the coil from the key switch ?
Do you know if the distributor shaft is turning ?
Have you checked the computer for trouble codes?
Did you use a new spring and button for the rotor ?
Let me know what you have checked so far and the results.

HEI distributor and burning coils,it in you connection first make sure you install primary and secondary prorperly as it comes out of the cap , and inside the cap wire from modules dont make contact if you are burning its from primary circuit, this is the (B+) or (battery most likely), your secondary is your tach and that need to switch from postitive to negative for it to create spark obvously if tach was grounded or applied power you wont start,but there are times the condensor in the distributor does stays fixed and shorts out the coil (replace that condensor its for suppression) when the condensor is replaced run a fused direct wire at B+ (from ignition) run the vehicle and monitor the tach wire and check to see if that get hot

1968 I was 3!I would say you are most likely going to have to find out from Chevy.If a dealer can't find out,probably a call to Detroit.Good luck! Greg

fuses and plugs check your grounds while your att it

also is the distributor button or rotor brush turning ??
i know it's a stupid question but i have seen the gears fall of the distributors

you are right the green should be the hot wire or positive just check with a auto parts store to make sure but im almost certain you will be ok.

ok,bring your #1 cylinder up to where both intake and exhaust valves are closed and your harmonic balancer timing marks are on 0 degrees,drop your distributor in where the rotor is pointing to #1 cylinder leave a little loose where you can turn it while running,mark where the rotor is pointing on the intake so when you put the cap on you will know where to put #1 plug wire,of course hook up all wires,now just behind the distributor on the firewall there is a brown single wire,unplug that wire while you use a timing light to set it at 8 degrees(while its running)once you set it to where it needs to be then tighten the distributor and plug that wire back in,its for the computer for electronic advancements.if the engine pops or bangs when you try to start it,then the timing is 180 degrees off,then all you have to do is lift the distibutor out and turn it exactly 180 degrees...NOW im only going through all of this not because i dont think you know what you are doing,its because i dont want to miss anything on the timing order to avoid complications for you.

Yes you can use the same tank, not the same filters though. I dont' know what year of car it is, but if it has an in the tank filter, if you ever have to change the fuel sending unit get rid of that filter. Some filters for FIs need constant pressure or they get air pockets. Also you may have to change out the sending unit in the tank depending on how new it is. The FI sendign units may require more "pressure" to **** gas through, though a electric fuel pump over a mechanical pump will probably work fine with it. As far as the distributor wires, depends on the dizzy you have. There should he a ground, and a live somewhere from the coil to the cap, and big red wire going to the coil. If you need to find the wired, and they are on the car, start at the source, start at the alt, and work your way back, there shouldn't be a direct wire from the battery to the distributor, unless someone intentionally jumped the wire. Good luck.
