Replaced battery and now won't start

Hi,

The battery in my car started to struggle a few days ago and yesterday did not have enough juice to turn the engine over. I went and go an Optima red top to replace it and after installing it the car turns over like a champ but suddenly will not catch. It is as if a solenoid shut off is tripped or there is no spark at the plugs. All I did was remove the old battery and attach the new one. Any thoughts?

Thanks!

Any chance you crossed the cables? Now think real hard and be honest? If so you might of shorted the BCM.

Okay, you did not cross them? Next you have to check to see if there is a fuse installed where the short pin should go in the fuse box under the hood. If so remove the fuse and you should be good to go.

Well lostinmars,

Looks like you are a winner! I definitely did not cross the cables. But I think your second theory is spot on. I spent a ton of time checking every fuse and in so doing noticed that one fuse was cockeyed and would not seat properly. Further examination showed that the fuse diagram did not show a fuse in that position. I removed the fuse on a lark and problem solved. But I am still puzzled about the whole thing. I do not really know what this slot is. When I replaced the battery I did not touch the fuse box so this fuse had to be in there since I bought the car a year ago. So why did it suddenly become a problem only after installing a new battery?

In any case, sounds like you figured out exactly what the problem is and had I not bumbled into the solution you would have solved my problem.

Thanks!

I presently have the same problem after changing the battery. Now my problem is that I cannot identify the short pin. Can you pass along any information in locating the short pin in the fuse box? I do not know what the short pin is.

I could not locate the what was the short fuse. No-one seemed to know what I was talking about when I asked them. I re-read the note that mentioned he looked at the fuse diagram and then he removed the fuse that was in a location that was not marked on the diagram. I then triple checked and on the top row at the right end there was a fuse that was not marked on the diagram. I removed it and the car started immediately.
