i have a 95 suburban with 5.7 tbi..its getting fuel to the throttle body,has spark,will start and run for few seconds on starting fluid.i replaced the ign module in the dist,,still no injector pulse,,book called for checking the ecm/pcm for problems,,replaced that and still no pulse,,i have 12 volts on hot wire to injectors with key on .wire that goes to ecm to ground injectors was checked with power and test light,,it flashed when cranked over but still no pulse with noid light hooked up... anybody have any ideas on what kind of problem this may be? i,m about ready to put it out of my misery.
