Etec 250- E250DPLSOC
Put a used Powerhead on, along with a new adapter plate. Got everything hooked up and got it started on the muffs (hard to start, figured it was air in the fuel lines from having it apart. Idled rough once it started but seemed to smooth out some the more it ran. Took it to the lake tonight and again very hard to start, turns over would fire and run for 2 seconds and die. Primer bulb was soft so squeezed that and got it firm. Cranked and fired several more times before it finally idled. Idled rough again. If I increased the rpm slightly it wasn't so rough. Tried to get on plane but wouldn't get over 2000 rpm and seemed very boggy. If I put it in neutral it would rev up better but not great. Pulled plugs and they are very dark and sooty, they were new and indexed when I mounted the Powerhead. Assumed it's from the fogging oil I put in the cylinders before ever turning it over.
To me it seems like it's out of timing (put my EMM from my blown motor into this used Powerhead)
I did upload the dat files for all the injectors
When I had it running on the muffs I dropped spark a cylinder at a time and on #4 when I did it the motor stopped, on the others it just sounded off and wanted to die.
Not sure where to go from here so any help is greatly appreciated.
