I've recently changed knock sensors, fuel injectors and the connectors, fuel pressure sensor, and spark plugs. I started it up and it idle rough and was smoking really bad. Went back in and realized some stuff got left unplugged. Fixed that and the car idle got smoother. However when I drive it. It drives good and idles fine, but when I cut the car off it won't start again. It turns over and trys to start but won't. I can hear the fuel pump cut on but it still won't start. Reset the ECU it starts right up and takes about 10 minutes and it idles smooth. When I cut it off it won't start.
