Did you disconnect CSV? It could be stuck and flooding itOriginally Posted by Bitsyncmaster
It's better to turn off fuel pump (via inertia switch), and try to start car with ether to verify integrity of ignition system and the engine itself.

It would only loose vacuum for the one cylinder.
...normally only a few inches when while cranking.

Well I ordered a compression gauge. Can't hurt to check it anyway. Never had checked it.

Mine only engages the CSV after one second or cranking. But I have also tried it with the hot start jumpered so it engages instantly.

I though of another possible cause. Timing chain broken. I would think I would hear a problem when cranking but I don't.

Dave,
Maybe you have already checked this. After cranking pull a couple of plugs and see if they are wet or dry. Knowing if it's flooding, or starved ,helps focus the troubleshooting.

Will try that today. Second thought on timing chain. Can't be that since I tested two plug wire for spark and distributor turns from the cam shaft.

Plug is dry after cranking. Tried a lot of starter fluid again and still no hint of any fire. All I can think off is it's not drawing any fuel into the cylinders. Don't really know what would make fuel condense on a plug. I'm going to try another ignition coil. I remember with my lawn tractor, I got spark on my timing light but that turned out to have a bad ignition coil.
Tried another coil. No change.

If timing chain broke, the engine would be locked up.
Try pulling plugs and ground on head and see spark color with helper cranking. Also make sure your plug wires are right.

All I did was pull the FD first time. Then second time I pulled the top half of the mixture unit to clean that roller bearing. Plugs and ignition distributor have not been touched. I did try stock ignition ECU, Stock Idle ECU and stock RPM relay just because those units use the ignition signal.
