I have 91 Camaro 3.1 L V6 FI that won't start.
Fuel pump works ok. Fuel Pressure on intake is 45 psi.Cheked FI wires, they all get the voltage.If I spray Carb Cleaner to TB it will start. I need some helps.....Thanks

 

Could goto a U pull it junk yard and get a used set of injectors to try. $10 maybe.

I find its best to pull what you need and then ask. Don't say what you need ahead of time just go look and find it. Make a pile of crap on the ground and say can I get this stuff for $20??? The answer is yes 99.9% of the time.

Someone else will need to chime in on which ones but you can steal injectors from many brands of cars. even fords.

 

go down to the parts store and buy what's called a noid light, you plug it in instead of the injector and crank the engine.

2 things could be happening, you could be getting no RPM signal to the computer(bad ignition module probably, they go bad all the time), or you could be in clear-flood mode. Make sure that the the signal voltage going to the ECM isn't close to 5 volts.

My best advice would be to take the ignition module out and take it down to AutoZone and have them test it. That's what i think it is.

BTW, do you get spark?
