Just bought the car. Told that it was an electrical problem, has fuel pressure at 40-45 psi. Has spark at each plug, changed plugs, new battery two days ago, had the alternator tested yesterday. Can hear fuel pump buzz when key turned on, checked OB1 codes just throws the number 12. Looks to have new coil packs, the plug wires are correct. New radiator with hoses, has been sitting for a about a year. The fuel tank is full of fuel. Starts then stall instantly.

try cleaning throttle plate on both sides and iac hole with choke cleaner. Also if any holes in air duct from air cleaner to throttle will cause that. code 12 means everything is normal sensor wise

Replaced the I.A.C with a new one and changed the fuel filter and cleaned the intake. It'll run maybe One to two seconds then stalls
