do i need the stock 8 spark plug distributor in order to get both coils to fire on z22 ?

do all of my wires appear to be on correct posts ?

 

i did swap the positive & negative on the new coil that is not working,

and new coil is still dead

(so i am going to move those wires back to where they were )

 

the other new coil fires great

and engine started right up  

but same 2nd coil has no spark like before 

 

so either the distributor is only for 4 plugs

or the thing inside distributor that spins

is not touching? (but when i swap coil to cap wires at dist cap... the good coil fires in either hole on dist cap)

 

or i have something else wrong

 Find the wire that has the 12v supply with the ignition on. That wire goes to the middle terminal. The other two don't really matter as they go to the coil negative terminals.

[720kingkab]

find the key-on wire

of the 3 inside the distributor ?

[720kingkab]

[720kingkab]

is it possible the ign module thing with wires hooked to go bad ever ?

could i move the wires inside this harness block

so both coils share the mount posts of the coil that does work ?

 

the bottom one (farthest to right in pic) with black wires is my main hot 12v that is also on center inside dist on ign module  correct ?

Yes, I think it should be the middle terminal.

Yes, but best to be sure the old one is bal or not wired properly

 

I see 3 wires correct?

Not likely. They have different diameter lugs to prevent mixing them up.

[720kingkab]

i see post size differences now 

once you point it out  

[720kingkab]

should both coils be firing at all times

regardless of rpm ?

or 2nd coil fire  just under certain throttle or acceleration positions? 

 

 

[datzenmike]

Both fire together at all times. The 4 wire module can shut off one coil under certain conditions.

[720kingkab]

with key in ON posotion

when i test each lead inside the dist block with 3 different size lug posts

all measure 11.44 volts are greater 

 

 

each of the 3 lugs inside the dist itself on the ign module

also measure 11.44 volts and fluctuate a little with key in run position 

 

with key off none of the posts have any voltage 

[720kingkab]

let me measure voltage at the dead coil posts now

[720kingkab]

with key on

each post on dead coil measures 11.44 on dmm

when 1 lead of dmm is on either coil post

and other lead of dmm is grounded to truck metal 

[720kingkab]

let me reconnect everything

then try swapping out coil to cap wires on both coils

to see if 1 coil to cap plug wire is bad 

[datzenmike]

Pull the wires off the module terminals and test for 12v

[720kingkab]

ok still nothing. 

 

the good coil fires perfectly regardless of which hole in top of dist cap i put wire in.

 

i measured ohms on each coil to cap plug wire

and they both measure same impedance 

 

so the coil to cap wires  are good

i did that with key on and off 

all wires have 11.44 volts when tested 

 

let me get a photo posted 

hang on
