Most likely its a fuel pump issue
should check fuel pressure
Install fuel pressure gauge.
Turn ignition on, with engine off.
Fuel pump relay may need to be commanded on a few times in order to obtain highest possible fuel pressure.
Do not start engine.
Command fuel pump relay on with a scan tool. Observe fuel pressure gauge with fuel pump commanded on.
Is fuel pressure within 55-62 psi (379-427 kPa)?
If not fuel pump is at fault
