I just tried to prime my GT3 after the winter and ran into a strange circumstance. When parked, everything was fine and battery fine. All my cars are on battery tenders.

To prime the engine, I pulled the fuel pump fuse (row C, slot 4). Before pulling the fuse, I turned the key to accessories and everything was fine. Strong lights on the dash, etc.

Once I pulled the fuse, I saw dimmer lights on the dash and the car won't turn over. Nothing. I assumed the battery was fine and it looked fine initially.

I put the fuse back in and I still get very dim dahs lights and the car still will not turn over. I'm now charging my jumper box, but this is confusing.

What could have happened when I pulled the fuel pump fuse?? I just wanted to prime the engine before starting.

Any help would be great. So frustrating.

 

Correlation is not causation. I am thinking there needs to be another explanation. My first thought is the battery is the real culprit.

 

I'm thinking the same thing and will be attempting a start later today.
Thanks.
