ok so im in the process of selling my supra :cry: (court fees :3d_frown: ) and the car was running flawlessly for months. so i get a call and someone wants to see the car. i put my ecu back in and replaced the battery and now? it wont start. and after careful examination i have found that i have no spark. i checked all my fuses checked my ecu everything is working but i have no spark. i dont have any extra ignitors or coil packs so i cant really check those. i also have a safc neo and avcr they both seem to be in working order. i just cant figure it out. and it was running mins before i messed with the ecu. i just dont understand.:icon_evil

check for codes

also, by the alternator, is the 2 wire cam position sensor. See if it is wet, dirty, wiring frayed, or anything else that looks out of the ordinary.
