1990 solerado just changed fuel filter truck has been sitting 3 yrs and old gas was never drained but new gas added today.when started it didn't want to run then started revving and wouldn't stop.
Fuel injectors may be partly clogged and streaming instead of misting. Fuel injection cleaner may get it but may need to be removed to clean them, but either way I would put some good fuel injection cleaner with additive to remove water from condensation too. Like Heet Gas-Line Antifreeze and Water Remover and some fuel injection cleaner. I guess you do not want to drop the fuel tank but it would be best to confirm its not rusted and drain it but you already put good on top of bad fuel.
