Our garage ministry has a 93 Chevy Lumina 3.1L Fuel Injected v-6 we are working on. The engine will crank but will not start. It has spark and the fuel pump cycles when first on and after every crank. Tried a shot of starting fluid in the intake hose but nothing happened. What next?

Try disconnecting the air intake hose from the throttle body spray in there it should fire up if your getting spark.

Okay, just tried spraying inthe throttle body but still nothing. I also checked the spark on two of the plugs and both fire well. ? How do I best check the fuel supply?

Hook up a fuel pressure tester to the fuel pressure test port on the fuel rail

If you've sprayed the fluid in the TB and have spark it should combustion and immediately stall-

Verify the valve and ignition timing before the fuel system-something is wrong here
