Sorry it not for my SC, but I can't find help anywhere else. I have a 95 Lumina 3.1 V6 and the fuel injectors aren't opening. The car just died one day and I towed it home. I have 47lbs of fuel at the fuel rail. I changed the fuel filter,fuel pressure regulator, and new injectors. Nobody can get a code either. I started the car with starter fluid and its getting spark. My friend said it might be the cam sensor or crank sensor not telling the injectors to pulsate for fuel. Can someone help? I'm getting low on money to be guessing on parts. The worst thing is that I'm spending money on a Lumina instead my SC! Thanks.
