I have a k1500 chevy pickup with a 350 motor It will not start all the time and shuts off when coming to a stop sometimes.
There is no ground single coming from the ecm to the injectors. I have replaced the ecm and throttle position, air idle, and map sensors. I also checked the ground wires and cleaned the conections.
I had something like this happen to my 1500, it also died when i put it in reverse. I changed the knock sensor and the rotor button on mine. It turned out the the cam gear ate up the distributor gear, so you may want to check that out.
