Engine was running a little rough found a faulty injector, I replaced all 3 injectors and spark plugs and now the engine just cranks and won’t start. I have spark and I have fuel, connecting to it with Suzuki software shows timing is at 7 degrees BTDC when key is on and cranking. While cranking from time to time it will back fire. I have tried using brake cleaner to fire it off and it still won’t crank up. Does anyone have any ideas on what could be the issue?
