I have a 88 ef which had a b16 in it but I have recently switched it out to a gsr. When I got it in and tried to start I got no spark and the fuel pump isnt coming on. Maybe ecu problems? I changed out the main relay because when I turn the key over the check engine light comes on but never goes off like norm but didn't fix anything. I have looked over the grounds under hood and it all loks tight but could this be a wire issue somewhere or ecu prob? Thanks for all the knowledge and help. Nick
