So yesterday when I started the car, it cranked but didn't fire. It did start on the 2nd try. Odd, I thought. So then on m way home, I was steady at 35 mph when, for about a second, the fire went out. I had nothing. Then it came back and all was well. So I was thinking that maybe the opti was having a bad day.
Fast forward to today and the car wouldn't start. Cranked, but wouldn't fire....didn't even try. I noticed I couldn't hear the fuel pump priming. I banged on the tank with a rubber dead blow and tried again. This time I heard the fuel pump prime and the car fired, but then quit. That was the last time I could get it to fire. I also noticed the fuel gauge is pegged full. Soooo, time to cut an access above the tank? |

If you have to turn the key on, off, on a couple of times to get it to load up enough pressure to start, points to a pump. If it's not spinning up at all on key-on, that also points to a bad pump, but I guess it could also be a bad relay. I've rarely seen a bad relay, at least in the 94-96 Impala SS environment anyway. I don't have a lot of experience with the F-body LT1s, so those more-experienced will hopefully speak up here.
