22 years later, How to restart after my own garage find. '73 1.7 Options

[914CLE]

So after 22 years in my garage, I can finally get around to restarting. At this point, drained the gas, replaced all fuel line hoses and most vacuum lines, plugs look good, spark looks good, fuel is spraying from all injectors. Adjusted lifters. Car won't start. Any suggestions as to trouble shoot? I've ohm'd out coil (it's fine), voltage to coil is 10V (I think it's enough) as it main supply sparks, all cylinders has sparks. Turns over, no firing. Changed points to Petronix II. Still nothing even with staring fluid ( I would think if it was fuel delivery, it would at least fire for a few seconds with starting fluid).

It ran before I garaged it.

Any suggestions, check lists to follow??

Do I need to hook up air filter and vacuum lines to get it to even start at a rough idle?

10V to coil is not sufficient unless that 10V was measured during cranking. When cranking, voltage will drop. If you have 10V with just the ignition on, it will be substantially less when cranking causing a weak or non existent spark. 2 volts of voltage drop between battery and coil is pretty high. Is battery fully charged and cranking swiftly or just slow cranking?

Be sure you have the spark plug wires routed correctly to match firing order.

You mention you have spark on all cylinders but is it a strong blue spark or just faint,weak, and yellowish? Likewise you mention you have injectors spraying but are they spraying a mist or just dribbling?

After you've tried cranking - are the plugs wet?

Also have you checked compression?

If engine has spark, fuel and compression occurring in the proper sequence, it will run. You're missing one of the three.

Lack of air filter wouldn't cause issues. However, I'm not sure what vacuum lines you've not connected. If they directly feed to the throttle body, or the plenum plug them to prevent mixture from being lean. The fact that starting fluid doesn't at least cough sounds like you're not getting spark when cranking.

You mention you have spark on all cylinders but is it a strong blue spark or just faint,weak, and yellowish? It seems to be strong and blue.

Likewise you mention you have injectors spraying but are they spraying a mist or just dribbling? I took 1&4 out and pointed upwards and cranked and a fine V mist.

After you've tried cranking - are the plugs wet? Black and wet.

Also have you checked compression? I check #1 so far and had just over 100, I'm going to check the rest this week, but need to get the grommet in my socket so I don't lose the plugs again under the tin...

The fact that starting fluid doesn't at least cough sounds like you're not getting spark when cranking. That's what I'm thinking, I ordered a new coil, what provides voltage to the coil, a relay or through a relay in the ignition switch, bad ground, bad + lead?
