hello!. I am having an issue with my 1982 280zx turbo, I have no pulse to the injectors. Previous owner connected the battery backwards and burned the ECU and a fusible link. I have replaced both and the car started and ran for 20 mins then shutoff on its own. The fuel pump works and i have fuel in the rail. i have it connected directly with a switch. i have spark to the spark plugs, if i add starter fluid to the intake the car runs. i have replaced the crack sensor too just in case but no luck. i also cleaned all the ground connections i saw in the bay. i have tested the injectors and they work, they just aren't getting pulse from the ECU or what ever triggers it. please help.
