FiTech EFI system

When you crank it over, and it momentarily runs, does it show tach on the handheld? sounds like it fires, then loses tach signal.

I'll check it again later when I get back home. It was showing tach, both in the selection and the actual tach rpm reading.
To be clear, it doesn't run then shut off, it fires intermittently, sometimes in succession.
I'll make sure to take note of the rpms on the handheld and when/if it shows a value.
