85 vette fuel problems
Hello , I have spark and the fuel rail is full of fuel. It turns over good but won't fire. All the fuses in the main fuse block are good. Are there any other fuses or sensors that I should be looking for ? Or does anyone have any other ideas? Any help would be very much appreciated, I'm ready to pull my hair out & I can't afford to lose anymore. lol Help please

Did you test your fuel pressure? I know you said that the rail is full of fuel, but pushing in the tap can tell you if there is pressure, but it might not be enough. Should be about 43 psi primed.
Ohm your injectors. They should all be about 16 Ohms. This is common and there seems to be a rash of injector problems here lately. It's caused by ethanol in the fuel we use now.
Let us know.

The rail full of fuel means nothing. Under 40 psi, and it may not even start no less run correctly. Put the gauge on the schrader valve, turn key to on, and you should get a 2 second prime from the fuel pump. Tell us what the reading is and we'll go from there.
