My TBI 1991 305 does not fire when cranking. Until the battery starts going dead. Which is then turning over at a slow revaluation. But it's still yellow (no fire). Is it my pick up coil? Or timing?

Question type: Maintenance & Repair

Sense I'm going to a 305. From a
350. Or just wire a knock sensor into
the original ECM.

Not sure what you got there on the new wiring. Do you have spark at the plugs? How is the fuel pressure?
