I reinstalled the factory 305 back in my Camaro. The cars turns but no spark to the coil. I’ve replaced the ICM, rotor is good, replaced the coil and check those cables to make sure they are good and they are.

Still not getting spark, anyone have another place to look

What’s the acv from pu coil to icm ? Icm has power to it ?

ACV?

yes, ac voltage while cranking from pickup coil !

Would I test it from the wire from the coil or from the ICM?

From the pickup coil, unplugged from the icm. What has your testing consisted of ? The ignition coil primary and secondary windings were ohmed and determined faulty ?

So far, replaced the ICM

I’ve taken the coil wire out and attached a spark plug to see it sparks and no fire

so you don’t know if the pink wire at coil has power key on engine off or cranking .Or power at the icm ? Sounds like you’re just loading up the parts cannon hoping to find the issue.

I have 12v to the coil

When switch is off the pink wire has no power, when I turn the ignition I get 12v

hei coil in cap or divorced coil hei ?

It’s a stock Distributor,

all stock for what ? Your vague answer doesn’t help you diagnose

Sorry, not trying to be vague and really appreciate your help. Just have trouble articulating the answer to your questions.

so not even tpi, your in the wrong section.
unplug the jumper from coil to icm see if pink wire has power key on and cranking. If it does ohm or test pickup coil while cranking pu coil ohm.500 to 1500 ohm range

I have 12v on the pink wire when, not losing power there

I’m checking the pickup coil now

What should it read so I have the meter on the right setting?

ac volts

It doesn’t read anything when I put it on ACV

if you were cranking the engine theirs your problem. You could ohm it to double check.

If that’s the problem does that mean you have to replace the pick up coil or the whole distributor?

You can just replace pickup coil, you have to remove and disassemble the distributor. It looks relatively new but despite it’s looks it should give a ohm reading and ac voltage while cranking.red lead on the com seems to be in the wrong spot.

So rather than get and replace the pick up I just went with a brand new distributor with everything and it still does fire. Any other suggestions?

Doesn’t fire

Your jumping the gun, vom lead was in the wrong position. If you remove the icm to coil lead does the white wire have continuity?

Yes, wires test good

How was spark tested ? Coil wire have really high resistance or open. By saying the wire ohms good how much resistance?
any change if tach is unplugged and test for spark ?

When you say VOM is in wrong position can you explain? What does VOM stand for? Sorry for the basic question…

Thanks again for your help

When I touch the white wire it comes up with .3 ohms

Vom is a volt ohm meter, the lead in read is in the spot for reading amps dc.

I went and bought a better unit,
When I reinstall the plug with the Ingnition switch still on, I hear the fuel pump kick in.
I’m getting gas just no fire.

As for trying to get spark, took a spare spark plug and hooked it to the coil plug to see if I got a spark. That’s how I checked it.

Does the ECM need to be reset?

The spark plug was grounded when cranking the engine? The ecm doesn’t need a reset .

Yes, and had no spark

If the coil wire is good, you have checked acv on the pu coil. Ignition coil ohms good primary and secondary windings. It is possible that the new distributor has a bad icm.

If you short the two meter leads while in an "ohms" scale, does the meter indicate zero?
