1998 Dodge Ram Truck won't start

Hello,

I had a dead battery, so I tried to charge it with the 225amp jump starting setting on my battery charger. No go, so I just put in a new battery.

Since then, I have not been able to start my truck. Never had any problems before with starting. Switched around the relays and checked all the fuses. Went ahead and changed the Fuel pump cause I had been getting some incorrect fuel level readings. I even got a new computer box as someone said it might be that. Still no start - it'll turn over, but won't start.

The only other symptom I'm noticing is that with the key on, the gauges are not registering any information like fuel level, battery voltage, temp/oil pressure.

I'm thinking I fried something trying to jump it with the 225amp jump, but not sure where to look.

Thanks,

Julian
