Question about 1988 Chevrolet K3500
You should have over 9psi while cranking with injectors working to start. if there is not enough presure it will not start. The computer tells the injectors to open, it actually controls the ground side of the injectors with power side always hot. the computer NEEDs the map sensor or it will not start, it needs crank and cam location sensors from the distributor, the TPS, etc. Plug all sensors in, check fuel presure, clear codes and start over, checking codes to determine what isn't working.
