When you are able to finally start the engine, does it idle poorly and smell like hell (super rich mixture smell)? Do you have to go really gently to get the rpm's to rise?
Why do I ask? Those were my symptoms - fixed after replacing the ETA.

If you get a rebuilt unit, plug it in to the harness, and test it for operation, before installing it (just in case it is DOA - don't ask how I know to do this).

Good luck!

PS: Jim's webpages have a lot of useful info...spend some time there.
