Engine Performance problem
1999 GMC Suburban V8 Four Wheel Drive Automatic 151000 miles

backed into a level parking stall to wait for wife getting fast food and decided to turn off engine to save gas. Of course she comes out 2 min. Latter. Now truck cranks wont start. Will start briefly with starter fluid dies when fluid burns off. Checked fuel pressure at test fitting 42psi need 60-66 could not do a complete test with cut-out on return line. Oh what to do

thanks johnny j

Could be the injector/s, fuel pressure regulator and fuel pump check valve leaking dropping the fuel pressure if not the fuel pump is weak
