Nope, ECM doesn't have an impact. Did the PO use the right electric fuel pump or one with too higher fuel pressure? Getting fuel flow right is a big step in getting the Weber to work properly.

Negative it has a brand new mechanical pump. He installed it when he started throwing parts at it trying to get it to run. I've already got a electric pump and regulator on the way. I'm struggling to find a wiring diagram for the ignition. It's getting intermittent spark. And the tach jumps while engine is off but key is on. And the dist. Pickup hums. I'm thinking he has is wired up to get 12volts thru the ecm and it's possibly wired incorrectly.
