The engine will start for a few seconds then dies. Dies even faster if you try to give it throttle. Any advice?

Check the fuel pressure to rule out the fuel filter/fuel pump if okay try cleaning out the idle air control valve/test the TPS and MAF sensors and see what happens.

Ok already took every fuel/air sensor off the vehicle and had them tested and cleaned. Fuel pressure is 61 psi just replaced fuel pump, filter, cap and rotor sark plugs and wires and all wiring on the fuel pump 6 hours ago. Ran when all that was done then recently started this little trend.

Is this a CPI or TBI fuel system

If its a CPI the pressure should be 60-66 psi and TBI 9-13psi
