Re: Fuel pump and digital dash Questions

I'm thinking maybe you have a loose wire or a blown fuse somewhere. Since you can get the pump to work on the test circuit it's not the pump.

I would start tracing your wires from all fuel injection circuits and see if maybe something was missed!

I replaced the computer with a new one and the truck started right up,no digital dash though and the brake light is on.I pulled the dash out and there is power to the speedo and when i give power to the speedo it comes on but when i put the dash back in ,nothing works
