Drove no problem, parked it. Next morning nothing. Cranks

Customer Question

Drove no problem, parked it. Next morning nothing. Cranks but won't start. No spark and no fuel. I have the no bus and gives me the 920,921 and 999 codes. I've swapped clusters, nothing. I've replaced crank, cam, Tps and output shaft sensors. The battery is a year old and reads good voltage. I replaced the the pcm with a brand new one today. I know the asd relay and fuel pump works because if I unplug the ecm plug(black plug on far right) the asd goes heywire and fuel pump will run non stop till I plug the end plug back in

Hello and welcome! My name isCustomerand I can assist you with your question. Does the TPS have a 5 volt reference going to it with the key on? Can I start by getting your VIN? Thank you!
