Is the fuel pump sometimes not priming when you turn the key to ON(II)? Start by measuring the fuel pressure and checking whether you have bright white-bluish spark at all four plugs. The mechanical timing is also something that you should check, as we mentioned above. When you see P0976 engine fault code on your engine code reader this description will help you.

The Transmission Control Module (TCM) uses Shift Solenoids to control the hydraulic pressure in the transmission which is needed to apply the various clutch packs in the transmission that provide the different gear ratios needed to efficiently propel the vehicle down the road. When the TCM detects a pressure control solenoid is not performing as desired, it will set code P0974.
