This problem has been baffling me for weeks. I'm trying to start my supra but all it does it crank with the tachometer moving. I've tried to start it up with starter fluid which brought it to ~550rpm before dropping back down to cranking. My timing is correct, TDC, CPS, and cam gear position should all be good. I've checked the spark plugs and they're okay. There's good gas in the tank and I can hear the gas pump running. Fuel sprayed out when I took off the cold injector tube. I've checked the EFI fuse and it's not blown. I tried different grounds with no luck still. Any advice would be greatly appreciated. I've tried to ask people on mk3 supra facebook for input and followed their advices and I'm still stuck.
