My 96 2.2L sonoma pickup quit dead.When restartig it just cranks and wont hit at all. Checked and had spark. Got some fuel when I loosened line on engine side of original fuel filter.Downloaded computer with "CarChip" but got no info. Im going to start with a new filter and maybe try to checke fuel press. Does anyone have a similiar experience that might help? thank you for any help
check fuel pressure-make SURE it's up to spec's. Unsure exactly what that number is on a 2.2 but someone out here will! Suspect fuel pump but troubleshoot first as there are other possibilities. JP
Try a squirt of ether on the air cleaner. If still no go, it may be a timing problem. Slipped or broken timing chain (or belt?).

i HAD THE SAME PROBLEM, IT WAS MY FUEL PUMP. i DID THE SAME BY CHECKING THE FUEL THE FUEL LINE ON ENGINE SIDE AND i HAD SPRAY. bEST WAY TO TELL IF YOU HAVE FUEL DELIVERY IS TURN THE KEY ON WITHOUT ENGAGING THE STARTER, IF YOU HEAR A WHINING SOUND IT MEANS THE PUMP IS WORKING, (THE REST I LEARNED FROM MY BUDDY WHOM IS A GM MECHANIC) THE NEXT THING TO CHECK IS CLOGGED FUEL LINES FROM FUEL FILTER TO INTAKE. tHE WAY T DO THIS IS TO LOCATE THE FUEL DELIVERY PRESSURE RELEASE WICH IS LOCATED ON THE FUEL LINE/RAIL WHICH RUNS HORIZONTALY ALONG THE FRON OF THE ENGINE. IT WILL HAVE A BLACK CAP THAT YOU WILL UNSCREW TO UNCOVE WHAT LOOKS ALOT LIKE A TIRE INFLATION VALVE. WITH THE KEY ON USE A SMALL SCREW DRIVER AND PRESS THE CENTER OF THE VALVE, IF YOU GET A IST OF GASLOINE THEN YOUR LINES ARE CLEAR. THE NEXT STEP IS TO HAVE THE FUEL INJECTORS CHECKED, I STRONGLY SUGGEST HAVING A CERTIFIED MECHANIC DO THIS AS THE IMPROPER REMOVAL F THE INJECTORS WILL DEFINITELY DAMAGE THE JETS MAKING THE INJECTOR COMPLETELY USELESS. HOPE THIS HELPS
