Question about 2000 GMC Sierra
Appears there is no problem with battery. engine wants to turn over but only sputters slightly, will not start or run.checked small pressure valve at injectors and seems to have plenty of pressure and fuel. tank is half full. before romoving truck from flatbed wrecker with truck on incline position, it started but was certainly starving for fuel and could not accelarate without killing motor. 3 or 4 days prior security light came on during starting and went out.
It sounds like ou may have a weak fuel pump. if all it does is sputter then its starved for fuel. you might also check for water in the tank if theres enough water built up it wont run right
