So I went to drive my pick up and I dove about 100 yard and died. I checked my fuel pump and was getting no power to it. So i checked my fuses my relay and bot a new computer. Nothing. There is no power to my b+ on my diagnostics. If I jump my fuel pump off the battery and it turns on. Any Ideas. Please help

 

I had a similar problem on my 89 pickup. I finally found that there was corrosion coming out of the EFI relay fuse. So the EFI relay was not getting enough power and at the same time not opening power up to the fuel pump. I just bypassed with another fused line going to the EFI relay. I hope this helps.
