Their is no codes either that pop up. Check engine light doesn't come on. But I can't get my truck to start it only cranks.

IP is Injector pump


ok open the T-valve and have someone turn the key on and fuel should pump out it


here other way but not sure if do it 96

Shown are jumpers on the 97+ Burb & truck makes it real easy to purge the filter after a replacement, also for force run to test lift pumps 12v to connector forces the run.
