Re: 4l60e 1-2 shift does not happen at WOT

Well, I'm assuming something in my fuel line is restricting. I thought I read that the amperage for this fuel pump was 25-30? Obviously I read that wrong.

The ground is good. The only wiring issue I could have is the the pump is running through my ezwiring truck harness(fused). I know these harness's are wired a little different but didn't think it would cause an issue.

I'm going to pull the filter between pump and rails to see if something got through and is restricting flow. If nothing is restricting that line I was going to run a separate wire from pump to relay.... Hoping it's something as simple as that.
