Re: Help With Searay alarm
Finally started to make good head way. I got two new mefi four ecms from Az speed and re pin mefi 3 harnesses to mefi 4 computers and ddint use jumper harness. Everything seems good. the only problem I am having is the boat starts and stalls and unless i use the throttles. Once started the boat will idle fine. No codes no alarms. I been reading on this forum about IAC muffler. I dont think mine has that. I have the 7.4 with flat top plenum. The flame arrestor comes out the side of plenum. This problem is nothing new, the boat has done this even on the motor that always ran. I dont think it has to do with the new computers. I did replace the Iac becase the old one was frozen shut.I have a Gm IAC stepper motor test it didnt do anything. Any one have suggestions. Thx Again.
