First off I would check fuel pressure .... more times then not changing the fuel pump will correct this ...... use an 85 vette fuel pump ......

I understand you changed everything on the ignition but did you check if its working? Stick a screw driver in the wire, hold it an 1/8 inch away from metal and have someone crank the car.
You said you saw the injectors squirting fuel so the car should spudder if the ignition was working. You might have a bad oil pressure sensor or a bad coil. Or a simple wire could of fell out on the distributor cap

good suggestions, he has fuel, his ignition module probably quit...mabye

Did you check the computer for error codes? Does sound like ignition or computer.

Make sure you have spark as suggested.

Check the fuse in the battery compartment near the ECM (computer).

I tested the fuel pressure. when iI turn the key on there is no pressure when i turn the engine over the pressure increases to 8 psi. I have ordered a new fuel pump for an 85 corvette fron the USA won't be here for 3 weeks.

that's a long time. how much pressure is needed for the car to run? don't want to see you wait 3 weeks, put new pump in and still no start...

LastC3AZ

needs a minimum of 9lbs but to run properly closer the 15lbs. the OEM pumps usually run close to minimum new ..... so no room for weakness ... the 85 can be set up at 13 - 15 lbs that will give the CFI all it needs ....
This may not totally cure the no start issue .... but its always a good place to start

Doug1

agree, has he confirmed spark for sure, either with a screw driver or another spark plug leaned on the ground?

Doug1

there is a fuse that can prevent it from having spark?
my wife's 350z has some kind of circuit that detects water levels(but not in the radiator cuzz I changed that out) and will prevent it from starting, self preservation kind of thing.

The fuse shuts off the ECM. The ECM controls everything.

It does sound like the fule pump. You need a minimum of 9 PSI. But if its squirting gas, even a little it should start and stall. Bottom line is if you were to pour gas down the the TBI's it should start even with a bad fuel pump. It will run for a second or two. While you are waitng see if you can get it to run by pouring a bit of gas in the TBI's.
