1993 no spark or fuel
1993 suburban 1500 5.7 tbi no spark or injector pulse, jumper fuel pump, pump activates, 12 volts to coil and ignition module. Any ideas as to what may control spark and fuel? Any help would be greatly appreciated.

Pick up coil in the distributor sends the negative trigger to the fuel injectors and the coil. Verify that you have power on 1 wire to each injector.
