Quick question
Installing a used EFI system on a previously carbed 502. Everything is working correctly as far as fuel pressure, spark, etc. with the exception of injector pulse. We have checked to make sure the computer is good on another boat, we can probe the harness at the dizzy and get the injectors to fire, but can't seem to get them to hit while we turn the motor over. We have the pictures connector left with no where to plug in, does some thing on it need to be jumped or connected? [ATTACH=CONFIG]561500[/ATTACH]

Zero power to injectors, fuel pump is good, relay isn't sending power down small pink wire from relay. But if back proved through the purple/white from back of dizzy injectors fire, but won't stop firing until you try to crank it, then they stop and won't start up again

You haven't mentioned if OE Mercury fuel injection or not, but if Mercruiser, have you looked at wiring diagrams ?
