Haha no biggy on the homer moment.

Haven't rewired the pump, but here is an interesting tidbit, which may be relevant.


Occasionally, at idle, I see my fuel pressure drop down to like 30 psi (normally it's at 36 psi).

This happens maybe 1/50 times that I look under the hood while it is running, even with a brand new fuel filter.

So, I figured maybe something is up with the pump voltage.

Checked voltage from hot side of pump to ground side of pump and hot side of pump to chassis, and both give 12 V.

I then repeated this when I "caught" the car at low fuel pressure at idle (30 psi) and the voltages were the same.

So I don't believe it's a voltage to the pump issue.

Really strange here...

EDIT:

as for the weak pump....I am saying if the pump is weak up top to the point where it is unable to still provide enough flow/pressure to keep the pressure in the rail at say 62 psi, then you will have to use more injector duty than you thought you would have had to.

This might be wrong, but it seems like a possibility to me. I really need a digital FP gauge, but don't feel like spending the $$$.
