dneufeld Posted May 11, 2005 Share Posted May 11, 2005 allrighty guys heres my problem. first off how can you tell an ecu is turned on an funtioning?, i have all the power leads to a constant 12v, is there one or two that need to be an ignition source?. im having a little trouble with my swap and i thiink the problem is the ecu isnt coming to life. now the final question is what pins need power, ground or a switched source to make the ecu work. thanks in advance guys Quote Link to comment Share on other sites More sharing options...

85Sub4WD Posted May 11, 2005 Share Posted May 11, 2005 what year car is it? follow the proceedure for reading codes, if nothing happens, the ECU is toast the best help I can give you for 87+ cars is here: http://www.finleyweb.net/default.asp?id=142 however it is not complete on the info for turbo cars Quote Link to comment Share on other sites More sharing options...
4WDFrenzy Posted May 11, 2005 Share Posted May 11, 2005 Also, make sure that there isn't a pungent burnt circuit smell. If this is present, time to catch the magic horsepower genie in another ecu. Quote Link to comment Share on other sites More sharing options...
