1984 corvette not getting fuel to the injectors already replaced fuel pump and relay, also not firing tried spraying starting fluid still doesn't try to start what could be the issue

You have wasted a lot of money buying stuff that is not needed.
Check the pulses from the crank shaft sensor.

Need to connect a fuel pressure gauge and see if you are getting sufficient pressure to the tbi

Here's a link peter. 1986 Corvette Fuel Pump Relay replace

Sounds like the Fuel pump relay.. When you turn on the key you should hear the relay click.. then 1-2 seconds later it will click again and turn the pump off until the car starts. This pressurerises the system so the car starts.. if this does not happen there is no pressure on the injectors.

Fuel pump relay may be weak. Try removing the connector from the oil pressure switch and connecting the terminals together so as to bypass the switch.
if this works, replace the relay.

fuel pump relay. ther 11.99. if thats not it check your fuel injectors. im 99.99% sure its your relay.

If the engine fired on ether it means that you have a fuel supply problem, check the fuel pump.

Fuel pump may be getting weak. If pressure is not high enough the injectors wont open.

Jim; have you confirm the fuel pum[ is working? If it is, you should get something out of the fuel rail. Sadly. Pump is a dealer recommended repair cause the pump is more than likely in the fuel tank. Thry should changre you filter at the same time.
