FiTech EFI system

Sorry i dozed on this, been slammed the last few days.

i'm assuming you switched the input from Tach to 2-wire? is it reading any RPM? check for spark?
Yes, switched from Tach to 2-wire (don't think it is called that anymore). Does have spark as it tried to fire a couple of times before backfiring thru the throttle body.
