I have.

Ithink my problem is that the ecu is not getting a tach signal. Just don't know how to fix it.

Mine had the exact same problem. No tach signal, bad ECU. It will start and run for a brief second from that initial shot from the injectors but die immediately after that. Check your blue tach signal wire. Maybe you have a bad connection.
