Question about 1991 Chevrolet Camaro
Starts but doesnt run on all cylinders. installed new ecm prom distributer temp sensor and coil. sometimes will start and run fine but not for long period of time. has 55 psi fuel pressure. can leave injector fuse out and car will stay running. has weak injector pulse. i think its a bad wire or ground. dont know where to start looking.
Mine had a similar problem, there is a wire that goes from the computer to the fuel rail and this wire sends info on how much fuel and when to inject the fuel... if that wire is grounding out then this will cause the lack of cylinders to fire and also explain the inconsistency. So i would start with the fuel rail..hope this is of some help
