I have a 1989 k 1500 Chevy Silverado 350 motor I just had the motor rebuilt. It turns over fine but it tries to start but will not fully run. I've set the timing to TDC. I'm still using the original throttle body and all the sensors our original also except for new PVC valve and O2 sensor and so on but all my sensors are old from the old motor do you think it could be the computer control module? Or something else? Have I forgotten something?RockyOct 02, 2021
