Hard starting and sputtering

When I went to work last night my Jimmy was hard to start. Usually it fires right up, but last night it took a little longer and it sputtered after it started. Once I left for work it ran fine. This morning when I left work for home it was harder to start and sputtered longer. Once I got home I shut it off and restarted it. It fired right up and didn't sputter.

Check your fuel pressure and scan for codes. It depends on what vin you have for fuel pressure if it's tbi it's 9-12 psi and if vinW then its' 55-61 psi. If it's a 2.2l then its' 41-47
