Throttle Body Fuel Injectors not spraying.

15

Asked by Jul 11, 2014 at 01:00 PM about the 1997 GMC Sierra 1500

Question type: Maintenance & Repair

Injectors not spraying into throttle.  I have verified fuel all the way from tank to the injector housing.  These are new (re-built) injectors.  Back story is that the vehicle quit running a block from the house.  The obvious issue was the lack of spray from the injectors henceforth I replaced those first.  Hindsight revealed the improbability of both injectors dying at the same time.  Reexamination revealed that direct introduction of "starter fluid" into the throttle fails to start the engine.  I am now looking at a "no spark" issue and considering replacement of coil pack and TPS.  
Any advise out there?
